Here in South Carolina, they're colloquially known as "spice," which amuses me as a fan of the movie Dune, but that is where the humor ends. About this time last year you would hear 2-3 stories a day on the news radio's local report about murders, assaults, and other violent crime where the perpetrator was on spice/bath salts at the time. Understanding that this is local news, which is usually nothing but bad news as a general rule, but it was getting to become commonplace. SLED (SC Law Enforcement Division, the state police force) has been fairly assertive with rooting out new variants but like you say Cary they just formulate a new one.
