I would actually try a little without the xanax cause how awesome would that be if it was better. It really is a different high than combustion. Maybe just vape a tiny amount, see how that feels. Of course, it will still be awesome either way.
They feel much, much better on the lungs. For some people, sometimes a big rip of smoke feels like your lungs are burning, makes you cough, a lot of the time smoke tastes nasty (That's probably the best thing about a vape that I haven't mentioned yet. Every hit of weed tastes like you got greens.) smoking can be really nasty sometimes. I think I already mentioned this, but it really conserves your weed. It's crazy how little you need to get so damn high, even when you have a serious tolerance. You can ever save the weed that's done (I swear it smells exactly like burnt popcorn). There's always a tiny bit of THC left. It doesn't take that long to accumulate an oz between a couple roommates, and an oz of vaped weed can make some strong brownies. Also, if you have no weed and can't get any, you can pack a huge bowl of already used weed and you can get high.
I would most certainly try someone else's vape first though. You gotta try a good one though, cause the good ones a really good and the bad ones are really, really bad. You might hate vapeping, some people do. Doubtful though
