NO NO NO NO NO NO

I can't stress this enough.

ALUMINUM FOIL IS NOT BAD FOR YOU!

It CAN be bad for you and please read ALL OF THIS to understand.

NO STUDY has proven that aluminum foil can potentially harm you through cooking, heating, or using as a heat conduit. ALTHOUGH, if you heat aluminum foil to the point that it begins to evaporate and burn, the FUMES FROM THAT CAN HURT YOU.

Now, for bud usage.

Do you hold your flame on the bowl for 25-30 second? Do you use a torch lighter for 5-10 seconds? Do you start a big bonfire and hold your aluminum foil boil over the fire for the duration of the session?

Do you get black tar like smoke arising from your bowl when heating?

NONE OF THOSE SYMPTOMS = a nice safe happy smoking session.
