I tried salvia again using quid method yesterday and became high within 5 minutes. Sometimes when i try salvia using quid method I don't notice anything until after 20 minutes or 30. In all cases where I became high early and had intense trips I had a lot of saliva in my mouth and started chewing as soon as I rinsed my mouth with mouthwash(listerine). So if the quid method doesn't work out well for you drink loads of water on the day that you intend to trip and if your mouth is still pretty dry chew some pepper for a few seconds.
I get high like 30 seconds after a hit of salvia. I dont know why it takes you so long. Also it is fun to play the abc's game. You try to say your abc's untill you trip and cant go on.
