I smoked when my partner grew his own, about 10 years ago. We smoked about once or twice a month. If I was depressed or stressed in any way, it was great - it put me into a happy, joyful hypomanic state. We broke up 6 years ago, and I'm not sure where he moved to.
Let me stress that he grew his own, so we knew what we were smoking. Some of the stuff you buy on the street is very different and can be mixed with who knows what.
About two years ago I tried some marijuana my step-daughter bought and it was just plain wierd - my vision got really acute, but nothing else happened. I don't trust stuff you buy on the street anymore.
