What are the risks?

As it is the case with most of the smoking psychoactive drugs, some users report about unpleasant feelings in their throats and lungs, as well as about headaches and mild irritability.

Contraindications

•    After having taken Salvia divinorum, users should not drive vehicles or operate machines.
•    Salvia divinorum should not be taken without sitter since some of the users attempt to get up and walk around. The presence of a sitter minimizes the risk of hurting or other problems.
•    Users who experience emotional or psychological difficulties in their life should be very prudent when choosing such psychoactive drugs as Salvia divinorum since its use may evoke worse problems.

•    People with Schizophrenic family members or those suffering initial psychiatric symptoms should avoid using Salvia divinorum since hallucinogenic drugs (as well as all powerful psychoactive chemicals) may evoke latent psychological or psychiatric problems.
