I've heard that people actually build up a reverse tolerance to salvia...meaning the more they smoke the lower their tolerance gets
There is more evidence suggesting that your tolerance does indeed go down with prolonged use, than the vice versa.
I used some 20x and didn't get much of an effect. I thought it was because i had built a tolerance from using alot of 10x the past few weeks, but i guess that wasn't the case. Even on 20x i have never gotten a real salvia trip. Do some people just not get as effected? if thats the case, is it something biologically with me, or mentally?
My guess is that you're either biologically insensitive (sorry) or you're not holding the hits in for very long. With something like Cannabis, you can inhale and exhale (or cough it up), that easy. With Salvia, it takes 20-30 seconds for your lungs to completely absorb the stuff.
