Safer and Responsible Use

Cannabis affects everyone in different ways. Understanding the health risks and potential benefits of cannabis and guidelines for safer use can help you make decisions that are right for you.

Canada's Lower-Risk Cannabis Use Guidelines provide 10 recommendations on safer cannabis use, if you choose to use cannabis. These recommendations focus on non-medical use of cannabis but should also be considered if you use cannabis for medical purposes.

  1. The most effective way to avoid the risks of cannabis use is to abstain from use.
  2. Delaying cannabis use, at least until after adolescence, will reduce the likelihood or severity of adverse health outcomes.
  3. Use products with low THC content and high CBD: THC ratios.
  4. Synthetic cannabis products, such as K2 and Spice, should be avoided.
  5. Avoid smoking burnt cannabis and choose safer inhalation methods including vaporizers, e-cigarette devices and edibles.
  6. If cannabis is smoked, avoid harmful practices such as inhaling deeply or breath-holding.
  7. Avoid frequent or intensive use, and limit consumption to occasional use, such as only one day a week or on weekends, or less.
  8. Do not drive or operate other machinery for at least 6 hours after using cannabis. Combining alcohol and cannabis increases impairment and should be avoided.
  9. People with a personal or family history of psychosis or substance use disorders, as well as pregnant women, should not use cannabis at all.
  10. Avoid combining any of the risk factors related to cannabis use. Multiple high-risk behaviours will amplify the likelihood or severity of adverse outcomes.
