Welcome back to the Deep Dive.

Today we're going to involve a bit of a mental shift.

Usually when we talk about health, you know, we're talking about biology.

We talk about cells, viruses, broken bones, clinical stuff.

Exactly.

The clinical stuff.

But today we are orienting our compass specifically toward the nursing students out there, the future community health nurses, and of course, as always, our dedicated lifelong learners.

The learner.

To talk about something much, much messier.

We are tackling a subject that is, wait, it's often misunderstood.

It's heavily stigmatized and it is absolutely critical to the health of our communities.

It really is.

We are diving into Chapter 30 of Community Health Nursing, a Canadian perspective.

This is the fifth edition.

The chapter is titled Substance Use and it's authored by Abe Altshorn and Victoria Smy.

And it is a dense chapter, but I think it's dense because it's so important.

It really challenges a lot of the preconceived notions people might have about, you know, drugs, alcohol, and the people who use them.

It really asks us to move beyond that purely biological view of addiction,

which is often where we stop, and to look at the social fabric that surrounds it all.

This is all about the street level reality of health.

I love that phrase, street level reality.

And to set that scene, I really want to describe the image that opens this chapter because it's a very specific choice by the editors.

It is not a picture of a hospital bed or a stethoscope or a clinic waiting room.

It's this gritty, realistic photo of an alleyway.

There's a red fire escape ladder climbing up a brick wall, some debris on the ground, lots of shadows.

It feels very urban, very street level.

It does.

Why start a nursing textbook chapter there?

Well, that visual context is so intentional, right?

It signals immediately that community health nursing doesn't just happen in these sterile environments with fluorescent lights.

It happens in the alleys, in the shelters, in the parks, and in the living rooms of the community.

It completely sets the tone for a discussion that's going to look at the reality of health where people actually live, not just where we wish they lived.

It frames the entire conversation around the social environment rather than just the clinical one.

Okay, so with that in mind, what is our mission for this deep dive?

We want to help you, the listener, understand substance use not as some kind of moral failing, but through the lens of social justice and equity.

Yes.

This isn't just about saying no to drugs.

It's about understanding why people say yes and what happens to them when they do.

Right.

And if you take one thing away from this whole discussion, one key concept to kind of anchor your practice, it should be the concept of praxis.

Praxis, okay.

The text references Kagan, Smith, and Chin to define this.

Yeah.

And praxis.

I mean, it isn't just a fancy academic word to throw around in an essay.

That's what I was about to say.

It means practice that is intentionally aimed at social justice.

Intentionally aimed.

I like that.

That's powerful.

Exactly.

It's all about disrupting structural inequities.

A community health nurse or CHN,

they're not just treating a symptom.

They're looking at the power dynamics and the structures that shape why that person is sick in the first place.

You're not just pulling the person out of the river.

You're going upstream to see why they fell in.

That's the one.

If you were just treating the wound, but you're ignoring the weapon, you are not engaging in praxis.

It is about combining knowledge, reflection, and action to transform the world, or at least your corner of it.

I love that.

Actionable social justice.

Okay.

So here is our roadmap for the next hour or so.

We're going to start by cleaning up our language, defining our terms, because words have so much power.

Oh, absolutely.

Then we're going to take a trip through Canadian history to see how our laws have evolved or failed from the early 1900s to today.

We'll look at the four pillars strategy.

Then we'll get into the heavy stuff.

Intersectionality, the link between trauma and use, and the crushing weight of stigma.

And finally, we will break down the specific levels of prevention from broad policy all the way down to protecting patients from the medical system It's a comprehensive journey, and it all starts with the vocabulary.

Right.

Language matters.

The chapter makes a huge point about this right out of the gate.

We are seeing a major shift away from the term substance abuse.

A huge shift.

And I think a lot of us group with that term, drug abuse, substance abuse.

Why is that leaving the lexicon?

Well, we're seeing a hard pivot.

In 2017, the U .S.

Office of National Drug Policy actually recommended that all departments stop using substance abuse.

And the reason is because it carries a massive load of judgment.

Think about that word abuse.

It implies a willful, violent, or malicious act.

It puts the blame on the person.

It implies that the person is the problem.

It assigns blame.

Instead, the recommendation is to use substance use disorders.

So it shifts from a moral accusation to a medical description.

Precisely.

Yeah.

It neutralizes the stigma, or at least it's an attempt to.

Okay, so let's deconstruct these definitions that are in the text because they are distinct.

And as a nursing student, you really need to know the difference.

First up, we have just plain substance use.

Right.

This is the generic umbrella term.

It covers everything.

If you drink a cup of coffee to wake up in the morning, that's substance use.

Guilty.

If you have a glass of wine with dinner, that is substance use.

If you use illegal drugs, it's still substance use.

The text really emphasizes avoiding this binary language here.

It's not automatically good or bad.

It just is.

It's just consumption.

We all engage in substance use in some form.

Okay.

Then we have problematic substance use.

This seems to be the sweet spot for nursing intervention.

Exactly.

This is the key focus.

Use becomes problematic when it leads to adverse consequences.

Okay.

And those consequences can be physical.

They can be legal, social, or interpersonal.

The focus isn't on the substance itself.

It's about the impact.

Can you give me an example of that distinction?

Sure.

You could have someone who drinks a glass of wine every single night and functions perfectly well.

That's substance use.

Right.

But you could have someone else who drinks the exact same amount, but maybe it interacts with their medication and causes them to faint, or they get behind the wheel of a car and get arrested.

That is problematic substance use.

So same volume, different consequence.

Exactly.

The volume might be similar, but the consequence is what defines the category.

If your use is causing you to miss work, fight with your spouse, or get arrested, it's crossed over into problematic.

Got it.

And how does that differ from dependence?

Dependence is progressive.

It affects the physiological and the cognitive dimensions.

The key markers here are tolerance and withdrawal.

So tolerance means you need more of the substance to get the same effect.

Your body adapts, and withdrawal means your body reacts negatively, you know, shakes, nausea, anxiety when you don't have it.

You can be dependent on something without it being a disorder, then.

You can, though they often go together.

Think about caffeine again.

Many of us are dependent on it.

We get headaches if we miss our morning coffee, but for most, it doesn't cause a disorder that disrupts our lives.

That's a great example.

Okay, and then there's the big one, the really loaded word, addiction.

The text actually notes that addiction is a contested term.

It's been removed from some medical diagnoses, including the DSM -5, because it's so hard to define, and frankly, it is loaded with stigma.

Right.

It's often used as a slur or a judgment rather than a clinical description.

When people say addict, they usually have a very specific and often negative stereotype in mind.

But the term is still used sometimes.

It is.

The text notes, we do still see the term used in what are called process addictions, like gambling or shopping, where there's no substance involved, but the behavioral loop is very similar.

Interesting.

Okay, now the chapter provides a really helpful breakdown of the DSM -5 framework.

That's the Diagnostic and Statistical Manual of Mental Disorders.

They list criteria for substance use disorders.

Let's walk through some of those signs, because this is what nurses are actually looking for during an assessment.

Sure.

The DSM -5,

it taking larger amounts than you intended?

Did you say you'd have one drink and you ended up having 10?

Okay.

Have you tried to cut down but failed?

Yeah.

Are you experiencing cravings?

Crucially, are you failing to fulfill obligations at work, school, or home?

The disorder is largely defined by how it messes up your life.

Yes.

It's functional.

Another big one listed is using despite physical hazards, like driving while impaired.

Oh, for sure.

Or swimming in dangerous conditions, things like that.

Right.

And continued use, despite knowing it's causing physical or psychological problems.

But, and this is a fascinating part of the chapter, there's a critique of the disorder label itself.

The text calls it the disorder debate.

Let's unpack that.

This is really interesting for critical thinkers.

The text argues that labeling something a disorder might pathologize behaviors that aren't actually problematic in all contexts.

It brings up the role of culture.

How so?

Well, think about a business culture, maybe high finance or advertising, where heavy drinking at lunches or dinners is not just accepted, it's expected.

It's a networking tool.

Right.

Is that person disordered?

Often, society says no, they're just doing business.

But if you take that same amount of alcohol and you put it in a different setting.

Exactly.

Compare that to someone using an illegal opioid who gets criminalized.

The behavior in similar, but the label disorder is applied very differently based on social acceptability and legality.

So disorder isn't a purely objective biological fact.

No, the text wants us to be aware that it has social edges.

It's constructed.

That really highlights how much of this is social, not just biological.

And that leads us perfectly to the distinction between licit and illicit substances.

This is simple, but so vital and often misunderstood by the public.

Licit just means legal,

prescription drugs, alcohol, caffeine, tobacco, and illicit, illegal heroin, cocaine, and until recently, cannabis.

But the text makes a critical point here.

Legality does not determine harm.

Say that again for the people in the back.

Legality does not determine harm.

Alcohol is fully licit, fully legal, yet it causes massive widespread harm, liver disease, accidents, violence.

Just because you can buy it at a store doesn't mean it's safe.

Conversely, some illicit substances might have lower toxicity profiles than alcohol.

The nurse needs to focus on the health impact, not just the legal status.

That is the perfect segue into part two, the Canadian context and history.

Because what is licit and what is illicit has changed wildly over time.

It's not some fixed objective list.

It has.

I mean, if we look back to the early 1900s in Canada, substances were largely unregulated.

You could buy patent medicines with opium or cocaine in them right at the general store.

The first big piece of legislation in Canada was the 1908 Opium Act.

And the text points out something really interesting about that act.

It wasn't really a health law, was it?

It wasn't written by doctors who were concerned about liver failure.

Not at all.

It was a moral issue and is deeply political.

The debates in parliament at the time condemned opium as evil and unchristian.

A moral panic.

Totally.

But if you scratch the surface, as the text does, you see it was tied deeply to the politics of religion and race at the time.

Specifically, anti -Asian sentiment in Vancouver following labor riots.

It wasn't about public health.

It was about social control of a specific population.

So our entire foundation for drug law in this country is moral judgment, not medical science.

That's the root of it.

Then we move to the prohibition era from 1918 to 1920.

Right, the temperance movement.

This was led by them, yes.

They believed alcohol was the root of all societal ills.

Domestic abuse,

poverty, laziness.

They thought if you banned the bottle, you'd cure society.

How did that work out?

Well, we look back on it now as a failed legislative strategy.

Failed is putting it mildly.

The text says it actually increased organized crime and alcohol Exactly.

It completely distorted the market.

When you ban something that people want, you don't stop the use.

You just drive it underground.

You create a black market.

And then there's no quality control.

None.

So the alcohol became more dangerous and you empower criminal organizations.

That lesson is so pivotal when we talk about modern drug policy bans, often create more collateral damage than they solve.

Which brings us to the war on drugs era.

This is the enforcement heavy approach that really dominated the late 20th century.

Mandatory minimum sentences, harsh policing, the just say no campaigns.

The text notes that critics define this as an approach that disproportionately affects racialized youth and indigenous peoples.

It fills prisons.

It's incredibly expensive.

And the data shows it hasn't stopped drug use.

It treats a health issue as a criminal issue.

So moving into the modern era, at least the early 2000s, we saw a shift toward the four pillars approach.

This sounds more structural, more balanced.

What are those pillars?

The four pillars are harm reduction, prevention, treatment, and enforcement.

Imagine a table.

It needs four legs to be stable, right?

So prevention is stopping it before it starts.

Treatment is helping people quit or manage their use.

Enforcement is dealing with the organized crime element.

And harm reduction.

That's about keeping people alive and safer while they are using.

That makes sense.

It sounds comprehensive.

It started gaining a lot of traction in the early 2000s, especially in places like Vancouver that were facing a massive HIV and overdose crisis.

But then history took a weird turn.

In 2007, something happened to that table.

This is a critical historical detail the authors include.

In 2007, Canada's strategy was renamed the National Anti -Drug Strategy.

And the federal government at the time removed one of the pillars.

They took out harm reduction.

What?

So they just kicked one of the legs out from under the table?

Essentially.

The focus shifted almost entirely back to enforcement and abstinence.

It was a regression.

Critics at the time pointed out that while the rest of the world, Europe, Australia was moving toward public health and harm reduction, Canada was moving backwards.

Back to a war on drugs mentality.

It was an ideological shift, not an evidence -based one.

And where are we now?

What's the current state?

The pendulum is swinging back, thankfully.

We're seeing a return to a comprehensive public health approach.

We've seen the legalization of marijuana.

And now there are active debates about the decriminalization of other substances to reduce the stigma and the legal harms.

We're slowly learning that you can't arrest your way out of a health crisis.

Holy.

It's fascinating how these laws just reflect the morals of the time more than the science.

Now I want to move to part three.

Intersectionality and the upstream view.

The authors use a great analogy here.

The river bank.

I feel like this is a staple in nursing education.

It is because it works so well.

Imagine you are standing by a river.

You see people drowning, so you jump in and you pull them out.

You do CPR.

You save them.

That's downstream care.

Right.

The immediate problem.

Treating the overdose, fixing the broken leg, detoxing the patient.

But eventually, if the bodies keep coming, you have to look up.

You have to ask, why are so many people falling into the river in the first place?

You have to go upstream.

You have to go upstream.

You need to see who is pushing them in or if the bridge is broken or if there's no fence.

Community health nursing is about working upstream.

And when we look upstream, we find this concept of intersectionality.

This is what helps us see that broken bridge more clearly.

Right.

Intersectionality explains how different aspects of a person's identity, their race, their class, their gender, their history, their ability, they all overlap to create unique experiences of oppression or privilege.

It's not just one thing.

So you're not just a woman or a person who uses drugs.

Exactly.

You are the intersection of all of those identities.

And that intersection creates a very specific reality for you.

The text references a specific study by Smy and others from 2011 about indigenous people on methadone.

What did they find there?

This study is a perfect example of intersectionality in action.

They looked at indigenous men and women on methadone maintenance treatment.

And they found that their barriers to health weren't just about the addiction itself.

It was poverty plus race plus gender plus HIV status.

All of these factors combined to create barriers that a single issue lens would totally miss.

So what kind of barriers are we talking about?

Well, for example, racism in the health care system made accessing their methadone daily very difficult.

They felt judged or unsafe just going to the pharmacy.

Poverty meant they had unstable housing, which makes keeping a strict medication schedule almost impossible.

And separate them.

You can't treat the substance use without addressing the poverty and the racism.

They're tangled together.

That connects directly to the statistics on violence and trauma that are presented in the chapter.

And these numbers are.

They're staggering.

They explain a lot of the why.

They're heavy.

The text states that 50 % of Canadian women and 33 % of men experience sexual or physical violence.

Half of all women.

Half.

That is a massive amount of trauma in the general population.

And there's a strong undeniable link between adverse childhood experiences, what we call ACs and substance use later in life.

So the substance use is often a coping mechanism for the trauma.

Precisely.

If you are in pain, emotional or physical, you seek relief.

If you don't have other tools, if you haven't been taught other coping mechanisms, drugs or alcohol become that relief.

It's self -medication.

It is.

And this leads to what we call concurrent disorders.

This is when mental health issues and substance use overlap.

The text emphasizes that they almost always overlap.

So they can't be treated in silos.

No.

Sending the depression to one clinic and the addiction to another, it just doesn't work.

They feed each other.

The trauma fuels the substance use and the substance use makes the mental health symptoms worse.

It's a cycle.

Another area where this intersectionality plays out is chronic pain.

This is a huge issue in nursing.

A huge issue.

It's another vicious cycle.

We know that trauma actually changes the way the brain processes pain.

So people with trauma histories often have complex chronic physical pain.

Okay.

But here's the barrier.

When they go to a doctor or a nurse complaining of pain, particularly if they look poor or have a known history of use, what happens?

They get labeled immediately.

They get labeled as drug -seeking.

The clinician suspects drug -seeking behavior rather than pain relief -seeking behavior.

That's a huge distinction.

It is.

And this leads to the undertreatment of pain, especially in homeless populations.

The text argues that our concerns about prescription misuse shouldn't stop us from adequately treating pain.

This is where cultural safety comes in.

Okay.

Define that concept for us.

Cultural safety is about respect and power.

It's about the practitioner, the nurse, reflecting on their own power and their own biases.

It's about ensuring the client feels safe and that their history and identity are respected.

In pain management, it means listening to the patient's report of pain and not immediately dismissing it because of their appearance or their history.

It means treating the person, not the stereotype you have in your head.

That leads us right into the absolute heart of the problem.

Stigma.

Part four.

The text has a box dedicated to defining stigma, referencing the sociologist Goffman.

Yeah.

Goffman defines stigma as an attribute of difference that is deemed less desirable.

It's a mark of disgrace.

It turns a whole unusual person into a tainted, discounted one.

And link and feeling break this down into five processes.

I think it's really important to walk through these because it shows how stigma is constructed.

It's not just a feeling, it's a machine.

It is a process.

Step one is labeling.

We apply a label like junkie, addict or crackhead.

We identify a difference and we name it.

Step two.

Stereotyping.

We link that label to undesirable characteristics.

We think, oh, they are dangerous or they are lazy or they are weak -willed.

Yeah.

We fill in the blanks with negatives.

Step three.

Othering.

This is the US versus them mentality.

We separate ourselves from the labeled group.

We think, I am normal.

They are different.

It completely disconnects our empathy.

Step four.

Status loss.

This is discrimination in action.

The person loses social standing.

They're looked down upon.

And finally, step five.

Power dynamics.

The stigmatized person is denied access to resources like housing, jobs or health care because they lack the power to fight back against the group that's doing the stigmatizing.

Now, here's the part that might be uncomfortable for some of our listeners, especially those in the profession.

The text discusses stigma in nursing.

It turns the mirror on the nurses themselves.

It does.

And it's brave to do so.

It discusses an uncomfortable truth.

Nurses often view substance use among their own colleagues as willful misconduct rather than as a health issue.

Wow.

Even within the profession, there's a lack of empathy.

And if nurses judge each other that harshly, imagine how they judge patients.

There is a critical thinking exercise mentioned in the text that I love.

It asks the reader to check their gut reaction to two different phrases.

Pregnant methadone client versus coffee drinker.

It's such a powerful internal check.

When you hear coffee drinker, you probably feel neutral or maybe even warm.

It sounds normal, relatable.

But when you hear pregnant methadone client,

what do you feel?

Do you feel judgment?

Do you feel fear?

Do you feel anger?

That gut reaction is stigma.

It's your implicit bias.

And you have to know it's there to fight it.

Exactly.

As a nurse, you have to recognize it to dismantle it.

If you walk into a patient's room with that judgment, the patient will know, and the therapeutic relationship is dead before it even starts.

Let's move to part five, harms and harm reduction.

We need to talk about the scope of the harm because while we want to reduce stigma, we can't ignore the real damage that substances do.

And again, we have to challenge our assumptions about where the harm comes from.

What do you think is the leading preventable cause of death in Canada?

I think most people's first guess would be opioids, given the news.

And that's a huge crisis.

But the answer is tobacco.

Cigarettes.

It cost the economy $16 .2 billion in 2012 alone.

Billions with a B.

Billions with a B.

And alcohol.

Alcohol is deeply involved in accidental deaths, boating, snowmereeling, driving.

The text notes that almost 40 % of boating deaths involve alcohol.

It's a massive public health hazard, yet we celebrate it in commercials.

Right.

And when we talk about illicit drugs, the text makes the point that context and geography really matter.

Yes, absolutely.

Fentanyl is often discussed as an urban, hospital -diverted issue, whereas crystal meth is frequently a rural issue because the labs are easier to hide in the country.

The geography of harm varies, so a nurse in downtown Toronto sees a very different landscape than a nurse in rural Saskatchewan.

So given all these harms, what is the harm reduction philosophy?

We heard earlier that it was removed from the national strategy in 2007, but what is it actually?

The core definition is this.

Policies and programs that aim to reduce negative consequences without necessarily requiring the cessation of use.

Okay, that last part is key.

It's the whole ballgame.

There's a mantra the text cites.

It's not what's nice, it's what works.

Exactly.

It's pragmatic.

It contrasts so sharply with the abstinence model, like Alcoholics Anonymous.

The abstinence model says, you must stop completely to get better.

Harm reduction says, let's meet people where they are at.

So the question isn't, how do we make you stop?

No, the question is, if you are going to use, how can we keep you alive?

How can we keep you from getting an infection?

It's a fundamental shift in the goal.

So what are some concrete examples of this?

Needle exchange programs.

So people don't get HIV or hepatitis C from sharing dirty needles.

Supervised consumption sites, where medical staff can intervene if there is an overdose.

Loxone kits to reverse overdoses.

Even e -cigarettes for smokers are a form of harm reduction, replacing smoke with vapor.

And wet shelters.

Wet shelters.

Shelters where you are allowed to drink alcohol are another example.

It keeps people housed and safe, even if they're still drinking.

The politics of this are so intense.

The text tells the story of Insight in Vancouver.

This was a legal battleground for years.

Insight is North America's first legal supervised injection site.

The federal government, during that anti -drug strategy era we talked about, wanted to shut it down.

What was their reasoning?

They called it a failed experiment that encouraged drug use.

But the advocates and the scientists fought back with data showing it was saving lives.

The Supreme Court of British Columbia and eventually the Supreme Court of Canada stepped in.

And what did they rule?

They ordered the government to let it stay open.

They ruled that closing it would deny citizens their constitutional right to life and security of the person.

It was a massive win for public health over political ideology.

There is also a research box spotlight in the text.

A study by Wallace, Barber, and Pauley called Sheltering Risks.

This one really highlights the complexity of implementation.

It shows that just saying you do harm reduction isn't enough.

This is such an important study for students to understand.

It looked at shelters that were trying to do harm reduction.

So they gave out clean needles to residents.

That's good, right?

That's harm reduction.

Seems like it.

But they still had a strict abstinence policy inside the shelter.

You couldn't use on -site.

So you give them the needle but then you tell them now take this outside into the alley.

Exactly.

And what happened?

People didn't want to go outside in the cold or risk losing their bed if they were leaving so they used in the washrooms or they hid their use under blankets.

Well, that's more dangerous.

It actually increased the overdose risk because they were using a loan and hiding.

If you overdose in a locked bathroom stall, no one can save you.

The text calls this suboptimal implementation.

You can't just do harm reduction halfway.

It can actually create new unintended risks.

That is a perfect example of how the details of a policy can have life or death consequences.

Speaking of real lives, let's talk about part six.

The ethics case study regarding pregnancy.

This is perhaps the most emotionally charged part of the chapter.

This is one of the most heart -wrenching sections for sure.

We're talking about neonatal abstinence syndrome or NAS.

This is when an infant is born physically dependent on opioids because the mother was using during pregnancy.

The baby experiences withdrawal tremors, feeding issues, sleep problems.

It's incredibly distressing to watch.

It sounds terrible.

And the instinct for society and maybe even for some nurses is to want to punish the mother to protect the child.

But the text describes something called the apprehension trap.

This is a devastating systemic failure.

Women are not unaware of the stigma.

They know that if they admit to substance use, there's a very high chance that child protective services will take their baby away.

So what do they do?

They avoid prenatal care.

They hide.

They don't go to the doctor because they're terrified.

And the consequence of missing all that prenatal care is often worse for the baby than the substance use itself.

Lack of nutrition, lack of monitoring, undetected complications.

That causes massive, massive harm.

And then the baby is apprehended anyway.

Right.

And the mother, now traumatized and grieving the loss of her child, returns to the street and uses substances to cope with that new pain.

And the cycle just repeats with the next pregnancy.

Apprehension often fuels the addiction instead of solving it.

So what is the nursing role here?

How do you break a cycle that's that vicious?

The text suggests a mantra.

Caring, not curing.

The goal is to build trust.

You want that mother coming in for checkups.

You look for subtle signs, missed appointments, little weight gain.

But you approach with support, not punishment.

You play the long game.

You focus on her parenting capacity, on her strengths.

If she fears you, she won't come back.

And then you can't help the baby or the mother.

You have to prioritize the relationship over the judgment.

Caring, not curing.

That's a powerful shift in perspective.

OK, now we're going to get into the real textbook core of the episode, the five levels of prevention.

This is likely what will be on the exam for the students listening.

So listen up.

We need to walk through primordial, primary, secondary, tertiary, and quaternary prevention.

These are the standard levels of public health prevention.

But they're applied here specifically to substance use.

Level one, primordial prevention.

This sounds ancient.

Think of it as before the beginning.

This is the biggest picture possible.

This is about preventing the risk factors of the risk factors.

So what does that look like in practice?

We're talking about broad social and economic policy, housing first strategies,

guaranteeing annual income, anti -poverty legislation.

If you reduce poverty, you reduce the stress and trauma that so often lead to substance use.

This is about changing the very structure of society.

So this is the ultimate upstream work.

The furthest upstream you can go.

OK, level two, primary prevention.

This is what most people think of as prevention.

It's about preventing problem use before it starts in individuals or communities.

This involves education and guidelines.

A great visual from the text here is Canada's low -risk alcohol drinking guidelines.

Right, I have that graphic in front of me.

It's very specific.

It is.

It sets clear limits.

For women, it recommends no more than 10 drinks a week, with no more than two on most days.

And for men?

15 drinks a week, with no more than three on most days.

And it also has these zeroes the limit situations.

Right, when you're driving, pregnant, or operating machinery.

Primary prevention also includes things like school anti -racism programs.

Because preventing racism prevents the trauma that leads to drug use and parenting programs.

It's all about building resilience in the population.

Got it.

Level three, secondary prevention.

This is early identification and treatment catching the problem when it starts to develop.

This is where screening tools come in.

Nurses use questionnaires to identify risk.

But the text notes a major constraint here.

The treatment gap.

Yeah, this is the harsh reality.

The treatment gap is the fact that wealthy people can get into rehab tomorrow, and poor people get put on wait lists for months or even years.

The system is not equitable.

So you might identify a problem.

But if you can't offer a timely solution because the bids are full or unaffordable, secondary prevention fails.

Okay.

Level four, tertiary prevention.

This is for people who are already using and perhaps have a disorder.

The goal is to reduce harm and treat the condition.

We've already talked about a lot of these needle exchanges, supervised consumption, managed alcohol programs.

The text also lists alanine here, which provides support for families.

Interestingly, the text mentions child welfare as intended tertiary prevention.

It's known to reduce harm to the child.

But notes that it often fails due to systemic racism and the overrepresentation of indigenous children in the system.

And finally, level five, quaternary prevention.

This one might be new to some people.

Quaternary prevention is a fascinating concept.

It's about protecting the client for the medical system itself.

It's about avoiding over -medicalization and labeling.

Can you give an example of that?

It's about letting the community or the individual define if their use is problematic, rather than the nurse walking in and immediately slapping the label addict on them.

It's about avoiding the harm that we as healthcare providers can cause with our judgments, our rigid protocols, and our stigma.

It's first do no harm, but applied to the social side of care.

Exactly.

A crucial and often overlooked part of nursing ethics.

That is a crucial addition.

Now, to bring this all to life, the chapter concludes with a case study about a man named Daryl.

Daryl's story brings all of these concepts together in one human being.

It's so powerful.

Daryl grew up in the cod fishing industry in eastern Canada.

When the industry collapsed, which is a structural economic event, a failure of primordial prevention, his family fell into poverty.

A huge upstream factor.

Huge.

And he started drinking at age 13.

And by the time we meet him in the case study.

He is homeless.

He's been kicked out of shelters for drinking.

He is drinking non -beverage alcohol, specifically mouthwash, because it's cheap and has a very high alcohol content.

Wow.

He's in the ER constantly for intoxication or injuries.

He's getting arrested for public nuisance.

He's sleeping rough.

He is the very picture of problematic use.

So what was the intervention for Daryl?

A managed alcohol program, or MAP.

This is a residential program that actually gives Daryl a controlled dose of wine or beer at regular intervals throughout the day.

Now, to the average person on the street, giving alcohol to an alcoholic sounds completely insane.

Explain the why.

Explain the logic here.

It's counterintuitive, but it is so effective.

First, it stops him from drinking toxic mouthwash, which was literally destroying his stomach lining.

OK.

Health benefit number one.

Second,

because he gets the alcohol as part of the program, he doesn't have to steal or beg to buy it.

So the crime and the nuisance calls to police, just stop.

Benefit number two, for the community.

Third, because he is stable and not going through the violent cycles of intoxication and withdrawal, he stays out of the expensive emergency room and the jail system.

Which saves the system an absolute fortune.

A fortune.

And most importantly, it creates stability.

He has housing.

He has a bed.

He has dignity.

He starts reconnecting with his family.

This is a perfect example of tertiary prevention.

It reduces the harm without demanding abstinence first.

It treats Daryl as a person, not a problem to be solved.

It meets him exactly where he is.

It's an incredible example.

So as we wrap up, let's look at the conclusion and the nursing practice implications.

The text introduces something called the EQIP framework.

EQIP is about equity -oriented care.

It summarizes four key dimensions for community health nurses to take into their practice every single day.

What are they?

One, inequity -responsive care.

You have to address the social determinants, the poverty, the housing, the racism.

Two.

Two, trauma and violence -informed care.

Assume trauma is present and act accordingly.

Don't re -traumatize your patients.

Three.

Three,

contextually tailored care.

Customize your care to the local reality of the specific patient.

What works in Toronto might not work in a remote community.

And four.

Four, culturally safe care.

Respect the person's history, their identity, and their lived experience.

And the final call to action for the nurses listening.

Nurses have to examine their own biases.

We all have them.

We have to advocate.

Advocacy is part of the job description.

We need to be pushing for those primordial policies like guaranteed income at the same time as we are handing out the clean needles for tertiary prevention.

You have to work at both ends of the river.

You have to.

And you have to remember that substance use is not a moral failing.

It is a complex health and social issue.

We have journeyed from the moral judgment of the 1908 Opium Act all the way to the compassion and pragmatism of managed alcohol programs.

It is a long road, but one we are hopefully walking together.

It connects the biology to the sociology.

It's the deep dive way.

Indeed it is.

Thank you for diving deep with us.
