Ive never smoked one but there is a quite easy way to make one
Its called a hit of "t" anyways you need a grinder that takes the keef or crystal nodules of usually dro or just crystally bud... and you just let it build up until you have alot then you can get empty pill capsules from usually the local pharmacy... my cvs carries them, there for making vitamins and shit like that. Anyways you put the nodules in the pill capsule, and pop it, and your supposed to get really messed up off it.
