typically i just let my oil dry out until it's crispy. often takes a week or two. but i have a vacuum pump and i was bored so i went ahead and vacuum purged a dish of honey. it was fun.
they say it gets all the butane out. i can't see how there would be a lot trapped to begin with. and if any were left, wouldn't it simply burn off when the oil is smoked?
yea but when it burns its usually being funneled into your lungs. but i guess i can see how it get the butane out, pulling out the gas trapped inside? but who knows. looks like a fun process none the less.
