Contra Costa Times has this story about salvia, something your kids may be using:
Bill Cooper hardly expected to dial into a world of Mazatec Indian shamanism when his phone went dead and he reached to borrow his son’s.
Then he saw one of the text messages: “hey, when were you fixen to blaze the salvia.”
Salvia divinorum, which local smoke shops sell in packets of dark, crushed-leaf extract — with a “strictly for incense use only” disclaimer — has spurred new laws in more than a dozen states in recent years amid a slew of online videos showing youths speaking or acting bizarrely after smoking it; and the well-publicized suicide of a Delaware teen in 2006, with the coroner listing salvia as a contributing cause.
In many of the videos, the smokers often start laughing uncontrollably, then are rendered incoherent by a forceful high that users describe as much shorter than LSD, but often more intense. …
According to a federal drug use survey … , an estimated 1.8 million people age 12 or older used Salvia divinorum at some point, including 750,000 that used it in the past year … . Contrast that with ecstasy, which was used by 2.1 million people in the same one-year period.
