Understand substance use. Support people. The public deserves to know, too.
Understand substance use without reducing someone to it. Learn about dependence, shame, choices and safety—and practise a different response.
For adults who use substances, do not use, support someone, or simply want to understand. No personal disclosure, sign-in or promise to change is required.
7 modules · Learn at your own pace · Plan around 40–55 minutes, including reflection; this is an estimate.

Module 1 / 7
Use is not a diagnosis
Separate substance use, physical dependence and a substance use disorder.
Start with the person, not a label
People use substances for different reasons: enjoyment, social connection, relief, treatment or avoiding withdrawal. Some use occasionally; some do not want help or a change. Asking a question does not mean someone has a substance use disorder. Do not impose a trauma story, a recovery identity or a prediction of rock bottom.
TRDP teaching interpretation
Physical dependence does not establish a substance use disorder
Physical dependence means the body has adapted to a regular substance supply; reducing or stopping it can bring withdrawal. This can happen with prescribed medication without a harmful pattern of use. A substance use disorder involves a pattern of clinically significant problems and requires appropriate assessment—not a judgement from a neighbour or a quiz.
Source-based explanation
Try it in everyday life · fictional scenario
A colleague mentions a medication they take every day. Someone says, ‘That means they have a substance-use problem.’
Try: ‘Taking a medicine regularly doesn’t tell us their diagnosis. Their health information is theirs to share.’
Address the assumption without asking the person to defend or disclose their medical history.
See the answer and explanation without taking the quiz
Their body has adapted; this alone does not establish a disorder. Exactly. Dependence describes adaptation, not a character judgement or an automatic diagnosis.
Keep this: Describe what you actually know. Leave diagnoses to qualified assessment.
Notice conditions and practical barriers without treating them as a person’s destiny.
Look beyond willpower
Canadian workforce guidance considers biological, psychological and social influences together. Health, mental health, relationships, housing and income can shape risk and protection. This is a framework for understanding complexity, not proof of what caused one person’s substance use.
Source-based explanation
Ask about the next practical need
A missed appointment may leave a person without care, but it does not tell you why they missed it. A phone, transport, food or a place to wait might be useful. Ask what would help, offer only what you can deliver, and do not promise services or access you have not checked.
TRDP teaching interpretation
Try it in everyday life · fictional scenario
A friend misses an appointment. You are tempted to call them ‘unmotivated.’
Try: ‘Do you want to talk about what got in the way? I can help look up the next appointment or a bus route.’
A question leaves room for information. A concrete offer avoids both blame and an unrealistic rescue promise.
See the answer and explanation without taking the quiz
The reason is unknown; ask before drawing conclusions. Yes. Separate the observed event from your interpretation.
Keep this: Respond to the barrier you can identify—not a story you have assumed.
Recognize public, structural and internalized stigma while keeping accountability possible.
Shame is not a safety plan
PHAC describes how stigma can be internalized as shame and social avoidance, and how fear of judgement can become a barrier to care. These pathways help explain possible harms; they do not establish that stigma caused every difficulty or that every person feels ashamed.
Source-based explanation
Be specific about harm; protect dignity
A person can owe money, break trust or cause harm without becoming a disposable person. Name the behaviour, the impact and the boundary. Avoid gossip, insults and a permanent verdict about their worth. Respect the terms a person chooses for themselves; do not impose a label on someone else.
TRDP teaching interpretation
Try it in everyday life · fictional scenario
Someone has not repaid a loan. A group starts spreading details about their substance use.
Try: ‘The unpaid loan is a real issue. I’m not lending more, and I’m not sharing their health information. We can discuss repayment privately.’
Accountability and privacy can coexist. You do not have to provide money, housing or unlimited support to treat someone with dignity.
See the answer and explanation without taking the quiz
‘I can’t lend more money. Let’s discuss the repayment plan privately.’ Yes. It names the boundary and preserves privacy without a character verdict.
Keep this: A behaviour may need repair. A person still deserves care and dignity.
Practice permission, listening and clear boundaries.
Listening leaves room for the other person’s choices.
Ask before giving advice
Person-centred guidance emphasizes a person’s own goals and choices. A useful opening is: ‘Would you like information, practical help, or just someone to listen?’ Someone can want information without wanting treatment. A change of goal is not permission for others to take control.
Source-based principle and TRDP script
Safety, choice and trust
Trauma- and violence-informed guidance emphasizes safety, choice and personal control without requiring a trauma disclosure. Explain what you can offer and what you cannot. Do not demand a story as the price of respect. If a conversation becomes threatening, you can step away and seek appropriate help.
Source-based principle and TRDP application
Try it in everyday life · fictional scenario
An adult says, ‘I’m not ready to stop, and I don’t want a lecture.’
Try: ‘Okay. Would you like any information about risks, or should we leave it here? I’m still not comfortable riding with someone who is impaired.’
You can accept a person’s decision about the conversation and state a firm boundary about your own safety.
See the answer and explanation without taking the quiz
Respect the refusal; keep your own safety boundaries. Yes. Voluntary participation and clear boundaries belong together.
Keep this: Permission is useful even when your concern is sincere.
Recognize the limits of this course and find emergency or clinical help.
An emergency is not a teaching moment
A suspected opioid overdose needs emergency help. Naloxone can temporarily reverse opioid effects; it does not replace emergency care. Use the emergency response link below, follow the exact kit instructions and the dispatcher. Do not wait to finish this module or identify the substance.
Health Canada guidance
No home withdrawal plan here
This course does not teach dosing, tapering, diagnosis or withdrawal management. Alcohol or benzodiazepine withdrawal can be dangerous when physical dependence is present. Seek medical advice before changing use, and do not stop prescribed medication without speaking with the prescriber. In Ontario, ConnexOntario can help locate services; a listing is not a guarantee of immediate access.
Source-based caution and scope boundary
Try it in everyday life · fictional scenario
A person cannot be woken and is not breathing normally. You are unsure what they took.
Call 911 now. Use the existing emergency response guidance and follow the dispatcher. Do not delay for an online lesson.
The urgent task is getting emergency help—not diagnosing the person or debating their choices.
See the answer and explanation without taking the quiz
Public education and links to appropriate safety and service guidance. Correct. The course supports learning without replacing emergency or clinical care.
Keep this: Education supports preparation. It must never delay emergency care.
Separate a source fact, a personal account and an untested interpretation.
Listen without extracting a story
People with lived or living experience can identify assumptions and access barriers that a draft misses. Invite voluntary review, agree on the role and compensation, and get permission for quotation or attribution. One account is valuable evidence of that person’s experience; it is not a prevalence estimate or a story you own.
TRDP contributor practice
A course is not proof of impact
This course is intended to help readers recognize stigma and respond with greater dignity. Reading it, getting quiz answers right or sharing it does not demonstrate stigma reduction or lives saved. Useful feedback can include confusion, exclusion, unintended harm and what someone found helpful. Record actual feedback and revise the exact version; do not turn a compliment into a clinical outcome.
TRDP interpretation and evaluation boundary
Try it in everyday life · fictional scenario
A learner says, ‘I liked the course.’ Someone wants to advertise that TRDP has reduced stigma.
Try: ‘We can report that feedback with permission. We have not yet measured a change in stigma.’
A positive response is a response—not a tested effect. Honest limits make corrections possible.
See the answer and explanation without taking the quiz
You worked through its educational material—not professional competence or a measured health benefit. Exactly. Keep learning, permission, competence and measured outcomes separate.
Keep this: Be willing to say: ‘That is what we know; this is what we still need to check.’
Understand reward learning, adaptation and stress—and the limits of a brain explanation.
TRDP teaching schematic based on alcohol reward-learning concepts. Not brain anatomy, a scan or a universal pattern of substance use.
1. Dopamine: learning, not just pleasure
Dopamine is a chemical messenger involved in learning and motivation. Alcohol research shows how it helps link cues—such as people or places—with expected effects. A cue can attract attention before drinking. Dopamine is not a pleasure meter or a measure of character.
Source-based explanation · NIAAA; alcohol-specific example
2. Tolerance, dependence and withdrawal
With repeated exposure, the body and brain can adapt. Tolerance means the same amount has less effect, or more is needed for a similar effect. Physical dependence means reducing or stopping can cause withdrawal. Neither tolerance nor withdrawal alone establishes a substance use disorder. Adaptation is not a reason to recommend a larger dose; this course gives no dosing or withdrawal-management plan.
Source-based explanation · CAMH; public safety boundary
3. Reward and relief can both reinforce behaviour
Alcohol use disorder research describes interacting reward, stress and decision-making circuits. Both pleasure and relief from withdrawal discomfort can reinforce drinking; repeated patterns can become habitual. This model does not describe every substance or person. A learned urge is not a command or proof of lost agency.
Source-based model · NIAAA; TRDP interpretation about agency
4. Plasticity is possibility, not a promise
Plasticity means the brain can change. In alcohol use disorder, some brain changes and related functions can improve with sustained recovery; the extent and timing vary. This does not promise a complete reset or a universal recovery deadline. Do not generalize an alcohol finding into a prediction about one person or another drug.
Source-based explanation · NIAAA; explicit limits
5. The person is bigger than the mechanism
A brain explanation can help replace blame with understanding. It cannot tell us why a particular person uses substances, what they enjoy, whether they want help or what support fits. Housing, relationships, pain, health care and personal goals still matter. Do not assume trauma, a permanent “broken brain”, inevitable decline or a need for treatment from substance use alone.
TRDP teaching interpretation; not a diagnostic or causal conclusion
Try it in everyday life · fictional scenario
An adult says, “Sometimes I’m looking for enjoyment; other times I just want the withdrawal discomfort to stop.”
Try: “Those are different experiences. Would you like me to listen, or help find medical information? I won’t guess what you need.”
This fictional example illustrates reward and relief, not a diagnosis. Seek clinical help for withdrawal concerns; do not use the diagram to plan self-treatment.
See the answer and explanation without taking the quiz
Learning and adaptation can affect behaviour; they do not diagnose a person or determine their future. Yes. Use neuroscience to understand possible mechanisms, while keeping individual context, dignity and uncertainty visible.
Keep this: An explanation can deepen empathy. It must not become a verdict or a self-treatment instruction.
Choose one action: replace a character label with a specific observation; ask permission before advice; check a practical barrier; or learn where emergency guidance is kept. You do not have to become someone’s counsellor to respond with dignity.
You can return to any module or finish here. No score or disclosure is required.
If you send feedback, identify the module, what was useful or harmful, and a source for a factual correction if available. Avoid identifying other people or sharing private health details. You can review without telling a personal story.
