theoretically it should be enough, but it depends on whether its pure, and if its cut (which it probably is) what its cut with

IMO coke is rubbish, ive done it a fair few times if someone sorts me out a free line..... then the only time its done me any favours is when i was on acid and mushrooms feeling a bit timid in central london, doing a bit of chazz gave me some confidence (probably a placebo effect).... all the other times i found it pointless

but still some of my freinds stick it up their nose every night, some one or two lines, some 3 grams a day..... when will they learn?
