Health Condition of Cannabis Consumers in the Canadian Population

Study Overview
=================
Brief Summary
-----------------
This study evaluates the health condition and its evolution with time of Cannabis consumers in the Canadian population.

Detailed Description
-----------------
In Canada, legalization of recreational use is likely to have decreased the perception of risks associated with Cannabis use, and means that the reported adverse effects of Cannabis are not so important, suggesting that Cannabis may be useful for their illness as an alternative or complementary therapeutic. More Canadian physicians prescribed Cannabis for their patients. Both Recreational and medical use of Cannabis increase and will continue to grow up in the next coming years. Regardless, the typology of Cannabis use, more information on the health condition of Cannabis consumers may be helpful for the medical prescription of Cannabis, in particular in older adults who are more at risk of side effects.
