Salvia is the commonly used name for Salvia divinorum, a hallucinogenic plant species that grows naturally in southern regions of Mexico and can also grow when cultivated in controlled circumstances. Although references to this plant in mainstream culture are fairly uncommon, it ranks in the top 10 of the substances used by U.S. teenagers for recreational purposes. Researchers from the University of Michigan follow ongoing trends in teen salvia abuse through a project called Monitoring the Future. Current findings from this project indicate that adolescent use of the plant/drug dropped somewhat in 2013.
