Yeah man, smoke it in a bulb with a cap on the end. It'll seal it in (less waste) and i think it vap's faster with a cap on it.
I once blew a line of dope that was 7 inches long, I was asleep in my passenger seat 3 hours later. So, yeah bad way to do it... Though that was probably me OD'n now that i think about it...
Then again, a week after ^^^ I licked a bag and i was twacked out for like 14 hours.
Personal preference is to vap it. No matter how much of it i have.
I dont use needles so... yeah... wouldnt even know where to begin.
