You can get a gram of pure(well relatively) JWH for like $40 on the internet, and that's enough for like 50 doses.
Yeah I knew a guy who came in to class a lot on some synthetic nonsense. He looked messed up, and he said he didn't even enjoy it. (He got drug-tested by his parents).
Depends on who the 50 doses are for. The first time I smoked jwh-018 I got fucking blasted off of 4-5mg, but after about a week and a half of smoking it a few times a day it would take me 50-60mg to get just as ridiculously high. I would give most people 5mg doses and they would love it, so that would be 200 doses for 40$
Christ the 1st time I smoked JWH it was pure powder out of a chillium, I was fucked, could not walk, barely talk. Apparently I was also shaking like violently, I didn't even notice until we started playing chess and when I'd go to grab a piece of the board I could visually see how much my hand was shaking.
