yeah very high percentage THC in nearly every variant of weed these days, for me having a joint with tiny sprinkles of weed completely fucks me up, I just choose to have hash with lower THC percentage, plus hash tastes nice.
I think that the really strong stuff should be for medical patients, or people with really high tolerance, because for a teenager that doesn't know what it can do, it can really ruin them if they keep having it, especially since the strong stuff is more addictive aswell.
