CANNABIS COMMERCE: Study Shows Commercial Sales, Not Decrim, Boost Usage and Psych Issues

Here's the kicker, mate: a new study says it ain't decriminalisation that drives up cannabis use — it's commercial sales. An international team dug into data from 2000 to 2025, and found that when cannabis goes on sale commercially, more people use it, and mental health issues like psychosis tick up. Decrim or strict regulation? No big change there. It's the business of selling that turns up the volume.
