Does anyone have any concrete evidence? Studies, etc...


It's not that I doubt it, but I'd like to know just how bad it is for you...
OatWillies420 Reviewed by OatWillies420 on . Is Aluminum Foil bad? Is aluminum foil bad even if you only use it like twice a month tops? i always use some aluminum foil for a nice gravity bong but never on custom pipes. I was wondering if it would be bad to put it on a homemade bong and use it as the bowl or should i find a better bowl? Rating: 5
