Yeah I know a woman who owns a head shop and sells pipes/bowls, etc and she was telling me that it is more of a "spiritual" drug, that people are supposed to use with meditation, and only in small doses, etc.
She said that people (younger people) will take it and smoke as much as they think they can, trying to get all fucked up and high, but it ends up being a bad buzz for them. She said it will basically take whatever your mindset is at the time and amplify it by a million, so if you are pissed off about life, or unhappy with your girlfriend, or think someone is so cute you could just eat their face, well, you get the point.
haha
I am not saying these zombie attacks were because of salvia though. Just shooting the breeze about it.
