the only way it would truly be 'bad' for u is if the foil was heated to its burning point...which u shouldnt be able to do with a bic light hittin a bong, true its not 'good' for u, but when u consider ur already inhaling smoke.. its really not all that bad

dont quote me on that...im high
Grava Flave Reviewed by Grava Flave on . Aluminum Foil bad for you? I made a gravity bong today, and i used a socket for the bowl. Then i had to make a filter so the weed wouldnt get sucked into the water...so i just got aluminum foil, and put it inside the socket and pocked tiny holes in it. Would it be bad to smoke it?
