i've been wondering about something for a while now.THC is the active ingredient in MJ, and when you vape you're getting the THC and leaving the other things behind. is there a difference in the THC (aside from levels) that gives different strains their different highs?

i would think that THC from one strain is the same for another, and it's the other (left behind) ingredients that give different strains their uniqueness. this would mean that all highs gotten from vaping are the same, aside from intensity.

am i totally off base?
