I've smoked pot a few times, but it was never that enjoyable. I drink moderately throughout a month (maybe like 4-5 chill at home beers), and generally get drunk like 1-2 times a month on weekends or special occasions. I like the taste of beer and whiskey, though, so it's something I'll always do. Nitrous was just a fun little 30 second laugh fest that has popped up at hippie shows I go to. The only drug I'd ever really advocate and the only one I'll do with any regularity are mushrooms. It's certainly not for everybody, but given the right circumstances, atmosphere, etc, mushrooms have really led to some of the best experiences I've ever had and really opened my mind to a lot of new things. That being said, it's been a few years since I've dabbled, but I plan to do some soon. It's always an eye opener.
