Talking about Cannabis

Talking to young adults and youth under 18

Have conversations early that reflect your own values toward the use of drugs and other substances such as alcohol and cigarettes.

It’s important to talk about the risks that come with using cannabis before 25. Until then, the brain isn’t fully developed and cannabis use can lead to problems that impact memory, learning, attention, judgment and decision making.

A good approach is to understand the facts. Taking anything that changes the way you think, act and feel could have consequences on major life areas. This could include poor performance in school and dropping out of things you enjoy.

If you know someone who is under 18, and they’re using or considering using cannabis, encourage them to think about where they do it, who they are with, why they are using, and what they are doing while using.

Remember this. Whether or not they express it, youth and teens care about your opinion. It matters and can help with decision making.

If you have children

Consider how to keep children safe in relation to cannabis:

  • Do not smoke cannabis in the home or around children
  • Keep cannabis and all drugs (alcohol, tobacco and tobacco-like products) locked up, out of sight, out of reach and in their original containers

If a child is exposed to cannabis and shows signs of distress, contact Poison & Drug Information Service (PADIS) (tollfree 1-800-332-1414) or Health Link (call 811 or 1-866-408-5465 for internet phone users).
