i have severe anxiety/agoraphobia and i agree cinderella 99 is pretty good with it.. clear headed energetic sativa high.. but smoke too much and you will freak out, with major paranoia and racing heart..probably influenced from the haze. but 1-3 hits and im goood, anything more and i cant stand it. growing c99 sort of sucks though, depending on pheno, they dont produce very much and can get quite stretchy and lanky(very tall) they usually smell really fruity, but it doesnt taste as good as it smells imo.
hands down the best of the best that i have had and grown is rks from reserva prevada. very similar to the high from c99 but much more calming and forgiving, not so racey.. but also clear headed. it smells a bit lemony and has some minty undertones. it grows pretty nice and produces a pretty good amount also. the smoke is very soft and smooth, very little lung expansion and tastes the same as it smells.
as far as kush strains, you couldnt pay me to smoke them.. very bad with my anxiety. usually indicas for me are no good at all.
the best for me a sativa skunk strains
