Fucking Combustion (mostly) Since February 2017
Are we sure it's healthy? I often feel the bad taste of the lighter gas.
Are you trying to hit it while heating? Otherwise there is no chance you are inhaling butane.
I've been using Dynavap vaporizers for a couple of years now, and I've never tasted butane.
What kind of butane are you using? What kind of torch?
