Yea, also check out www.erowid.org they have some pretty interesting thigs about salvia. Some people can take 2 hits of 5X extract and be totally gone for like 15 minutes. But the trip seems a LOT longer; "Depending on dosage, the Salvia experience can vary from a subtle, just-off-baseline state to a full-blown psychedelic experience. At higher doses users report dramatic time distortion, vivid imagery, encounters with beings, travel to other places, planets or times, living years as the paint on a wall or experiencing the full life of another individual. Needless to say these can be extremely powerful experiences and should only be attempted with a sitter. While most people remain unmoving during the experience, some individuals will attempt to get up and walk around while in a completely dissociated state."
