There has been alot of controversy and discussion on this toppic. but i would like to end those. i have a fact that will prove it.
(please sticky)
Smoking Using Aluminum Foil
Most brands of aluminum foil (Renoyld’s Wrap with the anti-stick coating and similar brands being the exception), are untreated and remain 99.9% aluminum (again with the .1% being residues and other agents in the manufacturing process)
In order to inhale aluminum it would have to be changed from a solid to a vapor. This requires a lot of heat. More heat than what it produced by a butane lighter. A butane lighter is not even capable of melting aluminum, if a lighter fails to melt the aluminum, it will not be able to change the aluminum into a vapor.
Conclusion
I put this together so individuals can make an educated decision on if they want to use aluminum foil for smoking marijuana.
