nope
even with gc/ms, i really doubt they'd look for it. unless they try to pick apart every non-blood chemical? idk if that's even possible unless you get a team of scientists, pay a month;s salary, and set them to work lol
not to mention salvinorin A's absurd potency... i imagine it'd be cleared from the body rather quickly
if you ever test positive for salvia, don't quote me lol. i haven't looked that much into pee testing. i hate pee testing, too many people get false negatives and false positives including me
