Not really related, but the other thing I found out recently that cannabis can cause is the worst panic attack I have ever experienced: a DPDR (derealization / depersonalization) panic attack. I’ve had regular panic attacks before. I get one a year, roughly, where I get essentially heart attack symptoms. But this was something else. It felt like something was truly, irrevocably broken with my mind and I couldn’t even describe what. Utterly terrifying. I was a heavy user but dropped it the next day.
