Depends how hot it is/how quickly you want to reload. I usually take two good pulls with the vape turned off. It'll still be fairly hot after that. If I want to reload quickly, I'll pop it open and blow on the crucible while it's in the slot. That'll usually do the job. If I have time, though, I'll just leave it open on my desk (with the mouthpiece pushed down and the vape placed far away from my stoned ass, of course).
