Frequently Asked Questions

Is cannabis safe to use?

Studies show that using cannabis under age 25 can affect how the brain develops. The damage can affect the person for the rest of their lives. Using under age 25 can affect memory, learning, attention, judgement, and decision-making—never mind how it affects the rest of the body.

How much cannabis, how often, and how you use it will affect how much and how long it can affect your health:

  • Lungs – Smoking cannabis can damage the lungs. Second-hand cannabis smoke is at least as harmful—or more harmful —than tobacco smoke.
  • Goals and performance – It can have a negative effect on how you do at work, school, and on your hobbies and activities. This is especially true for teens and young adults. Younger users have higher rates of being suspended, skip more school, and drop out more.
  • Memory and learning – It can affect your memory, learning, and attention.
  • Judgment and decision-making – It affects judgment and can lead to risky behaviour and poor decision making.
  • Mental Health – In some, especially teens and young adults, using cannabis often can increase the risk for mental health problems like depression, anxiety, and psychosis.
  • Dependency – Some studies show that early, regular use may be associated with a higher risk of addiction.
  • Other health risks – It can affect both the unborn and newborn baby. Toxins from cannabis pass to the unborn baby, and then in the breastmilk after birth.
