Hm, well I'm not sure 'metal' fumes, that kind of comment doesn't really make sense. Metal isn't going to 'fume' at the temperature of a lighter. *snip* you think that somehow 'fumes' from heating a piece of aluminum foil is absolutely awful for you, but the cornocopia of street drugs you take isn't. If you smoke anything that just fucking rekts your health, so not to make any assumptions on your DOC, just to point out *snip*.
It seems there's a lot of ignorance around here. I didn't enjoy the DMT, I'll try one more time later with a higher dose, but the whole alzheimers thing is a total myth (it's usually most commonly used in the meth smoking world, they are always having to vape their stuff off foil). Aluminum foil companies even said it doesn't cause it (and then add 'please don't smoke meth with out shit'). I bought a common tobacco/weed pipe and load it with cigarette ash.
