I sort of think, for me, the purpose is comfort and pain control: Vapes do it! Some have really long tubes on them, I'd think a shorter tube or suck harder! You'll either be light headed or whatever it is you want! IN all seriousness, if it helps what you are using it for, that is the best thing! I get high from just lower levels of pain! I can do so much more and am so much happier! Just a thot! Take care and good luck!:hippy:
