Did you know that the rate of cannabis or marijuana use is two times higher among Canadian youth aged 15-24 compared to adults? One in five teens aged 15 and 19 have used it in the past year (Statistics Canada, 2016).

Not to alarm you but with the legalization of marijuana, your teen might be wondering whether it would be ok for them to start using it too. While you can still say that “You can’t do it because it’s illegal” to your kids younger than 19, your legal-aged kids may begin showing interest. They may think that, “It’s now legal, so how bad could it be?”

The first thing to remember is not to panic. It’s actually great that your kids are initiating the conversation. This means that they look to you for guidance and your opinion matters to them. If they did not raise the question, there is value in talking to them while it’s still a hot topic. The more informed they are about cannabis and its effects, the less likely they’ll be swayed by peer pressure. The possibility is also higher that they’ll make good decisions.

Here are a few things to remember when talking to your kids about marijuana:

  1. Be open

    Don’t just say “No, you can’t use marijuana because I say so.” Everyone knows this never works. Using an authoritative tone will scare your kids away. You will lose a great opportunity to educate them. They will also be less likely to ask you for help in the future in case they have questions, are pressured into taking marijuana and are confused, or if they get high and need help to get home. It can place them in grave danger.

    Encourage honest and open dialogue. Listen to the reasons why they might want to try using marijuana. They might just be wondering why people take it and are curious about how it feels to be “high”. This is normal. Some might say that they heard from a friend that it can help them cope with stress or anxiety. Take this opportunity to ask why they might be feeling this way (what’s stressing them out?). Suggest healthier options to relax or let off steam. Avoid judgement and the tendency to lecture. Stay objective.

  2. Know the facts

    Learn more cannabis facts so that you can provide accurate information. More often than not, kids have a hazy idea about the effects of cannabis. They get information from peers, movies, and popular culture where marijuana is depicted as a harmless and fun drug. Newcomer kids can be especially vulnerable. Some may not be familiar at all with marijuana plus, they can be easily swayed by peer pressure because of their desire to fit in.

    Here are some important facts about marijuana and its effect on young people:

    • The earlier you use marijuana, the worse it will be for your body, specifically your brain. The prefrontal cortex, the part of the brain that controls reasoning and impulses, does not fully mature until around the age of 25. With early use, THC, the substance which gives the “high” in cannabis, affects the same machinery in the brain that directs brain development.
    • Scientific evidence shows that the use of cannabis during teen years can interfere with school performance and well-being. Young cannabis users are likely to experience the following:
      • difficulty holding back or controlling emotion
      • preference for high-excitement and low-effort activities
      • poor planning and judgement (rarely thinking of negative consequences)
      • more risky, impulsive behaviours, including experimenting with drugs and alcohol
    • Adolescents are 16% more prone to being addicted to cannabis. Sustained and regular use poses more danger to their health:
      • They become more prone to developing mental illness (such as schizophrenia, depression and anxiety disorders) especially if they use it frequently or if they have a family history of mental illness.
      • Prolonged use could also damage lung health and lead to bronchitis, lung infections and chronic (long term) cough.
    • Cannabis, combined with alcohol and other drugs can be lethal. The dangerous combination increases the likelihood of negative side effects (psychologically and physically) and when used before driving can greatly increase the risk of getting into a car accident.

  3. Be clear about your goals and stay positive

    Your goal should be clear to your kids: You want to support them and keep them safe from potential harm because you love them and care for their well-being. This is why you are countering misconceptions and giving them the right tools. The right tools are: accurate information, the freedom to weigh their options, and support to foresee consequences. Let them know that just because it’s legal, it doesn’t mean that it’s safe. They might just be forgetting that alcohol and cigarettes are legal too, and that just like cannabis, using (and abusing) has negative consequences. Be patient when talking to them. Trust that your kids will be smart enough to make the right decision.

  4. Model good behavior

    Children pattern their behavior from your actions. Show them positive ways of handling stress or healthy ways of recreation. If you drink or smoke pot, expect that your kids will you call you out on this. Maybe it’s time for you to re-evaluate the reasons why you drink or smoke. This can also be an opportunity to share what you have learned. Be open, honest and objective. Always communicate that you care for their health and well-being.

  5. Continue the dialogue

    You can have more than one conversation about marijuana with your kids. Look for good opportunities to broach the subject (so that it doesn’t seem like you’re nagging). It could be while watching a TV program featuring a character who uses marijuana, or hearing about news on the car radio. You can ask general questions like: “What do you think about the legalization of marijuana?” or “Do you have some questions about marijuana?” Keep the conversation informal. Let them know that you are always available to talk if they have other questions or concerns.
