Yeah, that's what I heard. If you actually light the aluminum and get all those nasty fumes and stuff and inhale that, say "bye bye" to your brain, but just letting the smoke go through it (like a bowl) is pretty harmless.

I'm pretty sure that brass is safe.. just wanted to make sure. By the way, don't tell me anything like: OMG!! DONT SMOKEG OUT UF ALUMINIUM!!1 iTS BaD 4 U OMG!! I know that. That's why I'm using brass, thanks. Rating: 5
