As far as I know, you just put the 'crushed' weed into the bulb, and hold it over a flame.

It should become hot enough to release the THC, but not hot enough to ignite.
TooFarGone Reviewed by TooFarGone on . Lightbulb Vape Okay, everyone, I need some info. I have a lightbulb vape that I made a loooooong time ago, but I don't know how to use it. I mean, do you just grind up the weed almost into a powder, put it over a candle until it fogs up, and then inhale? I just don't get it :confused:. Anyone who can vouch for the effectiveness of a lightbulb vape? Any other info? HELP ME, PLEASE! Thanks, Jake Rating: 5
