Well,
I'll admit that I'm not a pot connoisseur, but I do know that it's a mild hallucinogen and that, as so, it has the ability to induce panic or anxiety.
Everyone reacts to drugs differently; as I've mentioned before, there is no panacea for anxiety or depression. I used to smoke pot regularly (3-4 times/day), while in High School, but stopped smoking because it was making me increasingly insecure. Now, it seems, I have epic panic attacks when I smoke. When the bowl is finished, while everyone else is slumping into their chairs or stuffing their faces, I'm running around, like a basketcase, trying to find focus and some sense of meaningful occupation -I doubt that people like to get high with me as I can be kind of a buzz kill...
I've frequently used alcohol to cope with anxiety, but it's truly a bad idea, for me, as hangovers make me anxiety-prone.
Opiates are my favorite coping tool.
You just have to be careful that you use whichever drug you choose as temporary solution -although this is difficult, considering most drug solutions are addictive substances...
