Ok....well I have experimented with EVERYTHING.....I started smoking pot at parties when I was about 15, when I was 17 I started smoking daily and did until I was 21. I've done coke a handful of times and the same with extasy. I used to follow Phish (the band) around the country when I was younger....at that time I did a lot of experimenting with acid and mushrooms. I loved all of it and I had a GREAT time. Luckily for me I do NOT have an addictive personality. I watched many of my friends screw up with addictions and almost kill themselves. So I stopped messing around with it. I countinued smoking pot for a while.
I'm 22 now and in the last year I've smoked pot maybe 4 times. Which is REALLY good considering I did smoke all day everyday!
And for a while I ate Loratabs everyday. Once you start eating them everyday...you can't sleep with out them so it's hard to stop.
But I did.

Now, I drink occaisionally with friends and have a beer or a glass of wine from time to time with dinner. And if I'm with old friends (from my party days) I might smoke a little pot....but my tolerence for pot is gone and I'm a complete dork after I smoke it..so I try to resist.
