Salvia Divinorum has effects that can't be compared to other psychoactive substances: it gives a very personal experience. The effects can range from subtle to extremely violent. A unique plant!
The duration of a salvia trip is generally relatively short. When smoking, the effect of the extract is noticable usually already within 1 minute after use, and can reach its peak between 5 to 20 minutes. Then the effect slowly disappears, although you may have a few hours a slight light feeling.
