Canada's lower-risk cannabis use guidelines

Cannabis products are used by many people, yet use comes with various health risks. As cannabis use and distribution are becoming legal in many countries, including Canada, a group of international experts developed the Lower-Risk Cannabis Use Guidelines.

These guidelines are based on scientific evidence, identifying behaviours in the user’s control that influence the risk of health consequences from cannabis use.

This group of experts conducted a systematic review of up-to-date evidence and translated it into concrete recommendations on how to practically reduce such health risks.

The guidelines include 10 concrete recommendations, such as age of cannabis use initiation, use frequency or patterns, cannabis products (i.e., low- vs high-tetrahydrocannabinol content) used, and cannabis use and driving.

These guidelines can be distributed by health authorities as a science-based information tool for cannabis users to modify their use toward reducing at least some of the health risks. The scientific version of the guidelines have been published in the American Journal of Public Health (August 2017, Vol 107, No. 8).
