Dangers of Tinfoil?

get papers -_-

what brass cones are bad?
ah well probably... :)
how about lighter gases? are they bad? :)

To be entirely honest, I'm pretty sure smoking ANYTHING is bad for you somehow. I say if you can't afford a nice piece, then get some papers and learn to roll, bro. Keep your lungs clean for the green.

Here's a little info that may help, glass is best, but we can't all afford it(it's all I smoke out of) if you must use metal, steer clear of the following, foil-not only does it burn away and end up in your lungs, but there are chemicals coating it(hold a lighter to a piece for a couple seconds and look at the smoke that comes off)
NEVER SMOKE OUT OF GALVANIZED STEEL!!!! I can't stress this enough, when galvanized steel is heated, it releases cianide gas, bad juju there.
Copper is also bad
Brass and steel are your best bets as far as metal goes.

This is what I've been using (when I can't use my pure glass bong, because of "security" risks)..

Sobe bottle with fish tubing, a pen for the tube under the bowl, and a ratchet head/ pipe screen combo. It works great, and when you blow the smoke through a doob tube, ain't nothing but laundry smell.

what if you smoke out of a wooden bowl is that bad for you?
