When i was 13/14 i mixed with the wrong badass kinda people and i tried grass about 5 times. i smoked ciggerettes a whenever i could get them, sometimes i went out of my way to get them.
Now i'm over it. It's not "cool" to smoke...you're not a man if you do, fuck that. I occasionally smoke ciggerettes, it's bad because i'm fairly athletic but i don't do it much, my last ciggerette was about 4 weeks ago (going on a record here) Last time i smoked weed was for my last birthday (last August) me and two mates camped out and smoked it up the whole night, It was fun as hell! I'd like to do it again! ...but i'm smart enough to know that that's where the addictiveness begins. First you think "oh yeah, i'll do it again, it's fun." then you do the same thing two weeks later...then again, then you start getting into the habbit every week, then you become addicted. I learned from some of my friends' mistakes.
Anyway, i voted for occasionally.
