yea, it left a wierd smell. You have to watch what type of butane you use.

I found a way to test if your butane is pure or not.

Spray a spurt on a mirror and if after it dries there is a "smelly crusty" residue it is not the type of butane you want to be using.

The "type" of butane you want is "N-BUTANE"

the cheap "toxic" type is "ISOBUTANE"

some brands that are good:
COLIBRI, NEWPORT, CORA, CTC, COLTON, DUNHILL, DAVIDOFF, FACKELMAN, WIN, NIBO, SAROME, CALOR GAS MATCH, UNILIGHT, K2, SUPERGAS, VENTTI, VECTOR


Also, here is a guide for how much butane to use with how much skuff ot bud

Plant Material-|-Recommended amount Butane-|-Estimated Yield
1oz High quality bud-|-12oz-|-3-6g
1oz Average bud-|-10oz-|-2-4g
1oz low grade bud-|-9oz-|-2-3g
1oz high quality trim leaves-|-12oz-|-3-5g
1oz trim & leaves-|-10oz-|-2-4g
1oz fan leaves-|-8oz-|-1-2g
