Smoking salvia causes hallucinogenic experiences, emotional mood swings and a change in perception of reality, according to the National Institute on Drug Abuse. Salvia is a plant that is part of the mint family and people commonly refer to it as sage, explains Wikipedia.
Body sensations and a feeling of detachment are also symptoms of smoking salvia, reports the National Institute on Drug Abuse. These effects do not seem to last long, reportedly ranging from less than one minute to less than 30 minutes. There is insufficient evidence to prove that salvia causes recurring psychiatric issues in humans. The Controlled Substances Act does not regulate salvia, but there are laws in many states and countries regarding the use of salvia.
