The article you sourced is a very good one, well researched, and from one of the most highly-regarded sources there is. Thanks for the link. It reminded me to read it more carefully...I only scanned it, and it deserves more careful reading.
Ok, so there are a lot of people with serious mental problems who have been smoking pot for a long time.
My question to the data is, do these people have their mental problems CAUSED by smoking cannabis, or did these people already have mental issues that pushed them into cannabis as “self-medication”?
It’s sort of like saying “drinking alcohol causes stress” when in fact a lot of people drink alcohol as a sort of “coping mechanism” to stress.
