Because salvia and cough syrup are just déclassé, America's teens are now snorting bath salts to get high. The kids are calling it "Cloud Nine", and apparently it's a craze that's sweeping the nation. Don't go shoving that Ahava up your nose just yet, though. The "bath salts" being sold aren't your run-of-the-mill lavender and eucalyptus stuff. They're actually erstwhile chemicals, usually mephedrone and methylenedioxypyrovalerone, being passed off as seasoning salt, bath salts, or even fertilizer.
Both chemicals are powerful stimulants, said to be around four times more powerful than Ritalin and similar in effect to MDMA. Also, they're as addictive as meth. Great. Not surprisingly, lots of the people using this stuff are winding up in the hospital. So, to recap: the bath salts you use at home are totally fine; don't snort them. If, however, you are looking to get high, please do not buy these dumb, terrible drugs for the above reasons.
