Pot had an evolving effect on my mental state. When I first started to use it, the high was dumb, gigglely, mind-altering fun. This was the effect for the first few years, whenever I would partake.
However, I started to have panic attacks on it, where I would get extreme dry mouth and what felt like uneven heartbeat, as well as general unease.
I tried several kinds, of differing strengths, and in decreasing amounts, but I lost my ability to enjoy being high. I can still remember how great the feeling of a good high was, which is a bit frustrating.
I guess there is always alcohol
