Cannabis in Canada

Get the facts!

Did you know that using cannabis can have negative effects?

Cannabis use can:

  • Make it harder to learn and remember things. After using cannabis, you may have problems paying attention, remembering or learning things, and making decisions. Using cannabis can reduce your ability to perform well on the job or at school.
  • Affect mood and feelings. Cannabis use can cause anxiety or panic.
  • Affect mental health. Cannabis use can trigger a psychotic episode (not knowing what is real, experiencing paranoia, having disorganized thoughts, and in some cases having hallucinations).
  • Be addictive. Close to 1 in 10 adults who have ever used cannabis will develop an addiction to it. This statistic rises to about 1 in 6 for people who started using cannabis as a teenager.

Lower your risk:

  • To avoid health risks simply abstain from use.
  • Using occasionally has less risk to your health than regular use.
  • Cannabis can impair your driving skills. Impaired driving is against the law. Don’t use and drive.
  • Vaporizers or edibles reduce the risk to your lungs. When using edibles start with a small amount and wait (onset can take up to 2 hours)
  • Strains with high THC may cause more harm.

When to think about NOT using:

  • If you’re young. Using cannabis can change the way your brain grows and develops.
  • You have a family history of psychosis or other mental health problems.
  • During pregnancy
