  15. Brennan Sisk, the former cannabis coordinator for an NGO based in Fredericton, New Brunswick, argued that legalization has opened the door to peer-reviewed research on the health impact of marijuana and the development of industrial uses. Elsewhere in Canada, cannabis is permitted at age 19, except in Alberta, where the legal age is 18. Legally aged adults may possess up to 30 grams of cannabis when in public. They may also gift up to 30 grams of cannabis to another legally aged adult. Adults across the country can grow up to four plants at home, except in Manitoba and Quebec, which have banned home cultivation altogether. In most of the jurisdictions, the age of majority for cannabis possession and consumption is 19, save for Alberta and Quebec, where it’s 18, although Quebec’s new CAQ government recently announced plans to raise it to 21.

But what about for depression? Although anxiety and sleep are commonly cited reasons that people use cannabis, people also sometimes use it to lighten their mood, or to feel better. Another question that I hear, but which I see less addressed in the current literature, is also an important one: If I or a loved one suffer from depression, what impact does marijuana use have? Below, I’ll do my best to answer this question.
