If you're burning your stuff, don't worry about it. The smoke you are inhaling with your THC is much worse than the unburned carbon from a lighter.

But, for vaporizing, if you have a butane power source, everybody is crying about butane taste.

I am trying to get them to use a couple of neurons.

A lighter flame can give off unburned carbon, but not butane, it never makes it past the blue part.

A torch lighter will give off pure, tasteless, odorless heat.

FREE YOURSELF FROM THE PLUG!
