When I was 19, I tried pot for the first time. While I've tried it on very few occasions, it never did anything for me but make me feel paranoid! I never got the laid back and relaxed feelings with munchies that followed. Turns out that my father had the same reaction as I did when he tried it. Genetics? Perhaps.
When I was about 20-21, I had a boyfriend who enjoyed hash. Now that was a fun little recreational drug. I've only smoked it twice and then we broke up. I never craved it enough to find a dealer so that was the end of that.
All things considered, I'm glad I had the experience. I never felt compelled to try anything else. I mean, hell, if pot makes me paranoid then coke would probably put me in a coma! No thank you. I'll stick to whiskey and smokes...and an occasional cigar.
