Tell me how it is, I've never tried one but I want to ;-;
It's healthier than smoking, because you're really just "cooking" it.
Basically, it heats up the weed into a nice steam of straight THC, no carcinogens to be found.
Also, "Less is more" goes quite nicely with a vape. Imagine an ace of hearts card, then bend it into a "v". Fill the heart in the center with weed and that's good enough for 4 people to get ripped as forget.
If you want one, spend over $100 or it isn't worth it.
