Salvia divinorum: effects and use among YouTube usApril 23, 2010
It appears people posting videos of them tripping on salvia has a use after all; psychologists at San Diego State University have studied the behavioral effects of Salvia using YouTube video footage.
From the abstract:
‘Since salvia’s effects on humans are largely undocumented, this study provides the look at users in a non-laboratory environment (e.g. self-taped videos) exhibiting impairments and behaviors consistent with this powerful hallucinogen. Also, this study demonstrates the feasibility and shortcomings of using YouTube videos to assess emerging drugs and drug effects.
Read an article on the study on Mindhacks. BoingBoing also made a post on this.
