^^ comes in tablet form, as well as little squares that dissolve on your tongue (my favorite, i'll eat like 2-4 tabs a day, makes bupe feel great as well as oxy). but no you can't smoke it i dont believe... and prepare to get flamed.. smoking anything besides pot, crack, tobacco, meth or heroin usually results in the person getting attacked hardcore... HOWEVER, "cheese" heroin is cut with diphen and i think ppl smoke that shit, but its like 2% heroin and 10% diphen... the rest is probably old cheese lol. but no, dont smoke it, smoke your H and eat the benadryl, be safe!!
