I would imagine a similar trend is occuring in other major metropolitan cities, but from what I gather, cannabis is passé with the millenials, cocaine is what the cool kids are doing now.

As far as cannabis, one of the benefits I hope to see with its legalization here in Canada is for better data to be available for the understanding of the medicinal properties of cannabis. There is a lot of positive talk about CBD for instance, but the information still relies mostly on anecdotal evidence .

The science is still in its infancy.
