i feel stupid cause i thought i knew alot about weed n such but now all these ppl on here make me look like some fag who slaps 420 stickers on his ass before he goes to school but here it is what is hash ;-)
Hash is extracted THC from bud. Basically, it's what gets you high, without all the plant stuff. Look it up on erowid for more info.
If coffee is pot, hash is expresso. It is a way of removing most of the plant material and keeping all the THC so it is concentrated. Search on here for Ice hash or bubble hash for more info. There are a few ways to make hash but cold water seems the easiest and how I make it.
