Salva Divinorum is nothing, NOTHING like mushrooms, psilocin, from mushrooms, is a 5HT agonist, and salvinorin-A is a potent kappa opioid agonist, I haven't yet grown any, but I just havent got round to aqquiring a clone. Salvinorin A is shockingly gram-potent, active at around 250 micrograms, very physically disorienting, and becomes active almost instantly on inhalation of vapor or smoked salvia extract, I have actually experimented with its antidepressant properties, me and my fiancee have had some success using it.
many people get no effects from salvia, even highly potent extracts, as salvia very often "protects" those who aren't ready to breakthrough, even when smoked with the correct type of high-intensity jet flame lighter, I have heard of people even accidentally taking a hit of 5x extract, by accident, they mistook it for a friend's somewhat more common, and illegal herbage, inhaled, yet experienced no effects.
She wasn't ready to breakthrough, and so, did not.
