I was talking last night with someone who's been involved in social work as a graduate-degree professional in the SoCal area for about twenty years. She told me that what she's seen over the past few years is that everybody is now high. The strength of the materials available on the street is intense, more so than people using them realize. And in her clinical work, she's seen a massive increase in paranoia in the people she deals with, which she considers to be likely to be a result of the drug use.
It occurred to me that this might partly explain some (obviously not all) of the extreme behavior observed coming from the left, as the "legalized" marijuana is generally prevalent in leftist strongholds.
Any SMEs around who can address the actual paranoia effects of marijuana use, and any other evidence to support or refute the hypothesis?
My area of expertise is in how machines work. Brains are not mechanical engineering, so I'm seriously out of my lane beyond here.
