Doesn't aluminum need to be heated to several thousand degrees to put off carcinogenic fumes? Otherwise cooking on aluminum foil would be deadly...
Cooking doesn't usually go much higher than 200 - 250C (400 - 500F). Cigarettes (and I assume joints similarly) reach 900C (1650F) when puffing. I'm not sure at which point aluminum produces fumes, but I dont think the cooking argument holds up.
