Harmful Materials to use as bowls.

Why is Aluminum so harmful? I feel I should know this as I've taken a lot of Chemistry and such but haven't ever heard of Aluminum being overly harmful.

Manufactored metals tend to have chemicals on them that will release once burned. I believe there are links to aluminum foil chemicals (when burned) and alzheimer's as well.

Soft metals are just best to stay away from.

if it's a 'soft metal' it's not safe to use... soft metals include (but may not be al): carbon(i think that's a metal), lead, copper, and alumamumum.... that i know of.

what about those c02 cartridges? I've been using them to make homeade pipes and bongs for a while, I'll get one (empty obviously) and cut off the neck with a part of the main chamber for a bowl.
Is this harmful?

I'd think that was brass, maybe. I haven't seen CO2 cartridges since 8th grade, when we built little race cars in Technology class.
