hey, well about two weeks ago me and some friends got some pretty decent bud, about half O. well, me and my friend split it. although, when i was at his house and we were gonna go smoke his stuff (two weeks later/lastnight) we found this white stuff all over it and it seemed like some type of mold or something. I know this isn't good but has anyone seen anything like this? what are the effects? has this happened to you guys? i am pretty sure they are not crystals cause weed doesn't crystalize by itself
