dude i've smoked bongs with aluminum foil for years and there's nothing wrong with me...it's not half the damage that cigarettes do to your lungs (which i smoke also)....i've been smokin and smokin and smokin for years and i'm fine, pot is not too bad on your lungs, and the trace amounts of aluminum that MIGHT burn are negligible...if all the resin melts through the holes in it (or if you're just paranoid about that like i am) then make a little bowl for the resin out of tin foil WITH NO HOLES IN IT and sit the bowl of resin down in a spoon filled with water or alcohol....light the spoon up under, let the alcohol or water boil or burn and that will burn the tin foil just enough to vaporize the resin and it'll smoke...but make sure you inhale the smoke!!! if you don't want all this trouble then just try smoking the resin in a 20-ounce bottle with tin foil for a bowl, or roll it up with a joint of some good ganja, or eat it if it's good enough, but it in a shot of STRONG alcohol (like everclear) and let it dissolve and then drink it if you can't find a way to smoke it....
