yeah, you would know if you were smoking salvia. Salvia is a really fucked up trip...you'd be lucky to get more than one phat hit before you lost your mind and didn't know where you were at for a minute. That shit is getting really popular lately. But what people don't know is how it effects you long term. A good friend of mine had his brain turned to mush because of Salvia. that stuff is bad news, i recommend staying away from it.
