The vape was a success

lol so i bought my dad a vape for his 50th birthday, they used it a few days early, and they said it got them super messed up. So here's the problem, they are having issues with using it, since they're not quite sure how everything goes, they dont really have the hang of it.

So could a couple of you experienced vape users give me some hints or tips to pass on to them?

tell them to vape it up their ass it gets you super messed up

what kinda vape did you buy? a volcano? what kinda issues are they having?
