Do about 1/8; a baggie of about 10-12 stems with tops should do you if you weigh about 150-200 lbs. expect a mellow gradual build up- it ain't like acid, it won't HIT you or anything. feel real mellow, maybe get the gigglies for 1-3 hours, but feel happy with everything, tough to explain, I did my first just last year, and LOVED it. btw, I'm 46 and have tried most everything else except that till last yr. make sure you have absolutely no place you gotta be, and there are no downer people present, y'know negative idiots don't drink too much, you have much bigger tolerance for booze, until you're off of it, then it'll hit you like ton of bricks. smoking is nice with it, it'll kind of carry it out longer, expect to be high for 5-10 hours noce trippy, mellow high... damn I miss it...
