There are many argugents for and against how aluminium can cause alzheimers and if the lighter is hot enough to vapourise it bla bla.

Im sure smoking out of a can is something a lot of people have done when new to smoking (me included). If you are really worried about it dont do it. But IMO it wont hurt to do it a few times.
dean0000 Reviewed by dean0000 on . smoking through a soda can? I have heard that smoking through a soda can is bad for your brain and causes some type of mental problem or something. Whatever it maybe, is using a can bad for your health, or is it just a common misconception. I use this technique when im really desperate and i dont have a piece, but even then is it still bad for u? Rating: 5
