new plan for u
1) hang out with some of ur experienced stoner buddies who u TRUST
2) buy a LOT of weed off one of their dealers [4grams approx]
3) smoke it ALL AT ONCE, or little breaks between every 2 bowls or so, go do somethign stupid, eheh
4) be high

BTW i got high my first time cuz we smoked an eighth of really really REALLY good bc bud, and man.. i was trippin.. but make sure u trust at least one of the ppl you're with really well
