Yea right dude! When you take this special weed that grows in caves (giving it hallucinogenic properties) then you take out the THC it makes salvia, which is why it is legal (no thc).
Hahahahaha...I really hope you aren''t serious...It's in no way related to weed except kids use it as a "weed substitute" when they cant smoke cause they are getting drug tested...they generally tend to do this once because they didnt realize how intense a salvia trip is...all the youtube videos of kids getting fucked with while they are on salvia are really fucked up...those kids are laughing simply because of the drug but inside they are tripping hard and mentally unstable because they were ill prepared for how intense it actually is...
