Undeniable facts:

* Cannabis is a common psychosis trigger to those with an existing disposition (even if they don’t know it yet).

* Legal access to cannabis increases the number of people using it. This sounds obvious, and it is, but the most bandwagonny drive-by harm reduction advocates will deny it.

* There is a lesser frequency of psychotic episodes in heavy users because plenty of people learn to stay away from their psychosis triggers once they know what they are. Those that continue, are somewhat less likely to present to a hospital (voluntarily).

All of these things are true, yet this article is still pearl clutching bait.
