I'm glad someone felt the responsibility of informing others about the harmful effects of smoking with foil. I feel therefore, it is my responsibility to caution everyone to avoid using copper in the assembly of homemade smoking devices. I don't remember the exact damage it does to you, but speaking from personal experience, it fucks up your lungs.
As tempting as the plumbing aisle of your local hardware store is, do not use copper fitting or pipes! Steel, stainless if available works best, but as a general rule if it is colored, stay away.

Peas out
LonerStoner Reviewed by LonerStoner on . FOIL! i'm quite concerned that people are being advised to use foil when making bongs and pipes. DON'T! it is a major contributor in giving you altzhiehmers and it makes white spots on your lungs :eek: . try using the metal casing from those small 'tea light' candles instead. it's more solid, and doesn't give off carcenogenic fumes.
