I am not an expert on the risks of marijuana overall.I see people become somewhat paranoid or unmotivated, but a quick search of the medical literature did not seem to comment on whether those are recognized risks in larger samples than the patients I've seen.A substance use expert could comment better on that.They are literally using the herb to control their mood. Often they use very tiny amounts, but usually daily.They usually seem to stop using if we have success controlling their mood with typical mood stabilizers, as though they found the drugs better than the herb.These are very anecdotal observations and should be interpreted as such...
