most people will say it's a waste and not to do it and it doesn't work but i dont smoke weed, i smoke cigs and if im going to smoke an "alternative" i smoke blue lilly and blue lotus and i HAVE sprinkled some on top of some blue lilly in my bowl in the past and smoked it and it actually worked that way, you get a head rush and then you're benzo'd out.. i haven't tried ever smoking it off foil. i've never smoked anything off foil, H i used to get is east coast powder since i live in New England but i was mostly into OC's but im off track.. try sprinkling a little on some trees or tobacco or your smoke of choice and it's a hit or miss thing, works for some, others it doesn't. good thing is there's no binders or fillers to fuck up your lungs since it's pure powder (hopefully).. have fun. be safe. start low and work up. remember you can take more but you cant take less once you've taken it, and avoid the urge to keep redosing on phenaz because you WILL black out and usually they dont end good.
