From the Huffington Post:
The sale of synthetic marijuana has been banned in New York following a warning issued by the state's health department.
The "legal pot" products have been popping up in bodegas and smoke shops around the state under innocuous names such as Mr. Nice Guy, Spice, and K2 (we always saw these suspiciously pot-looking vials but were too afraid to ask what the hell they were).
In New York City alone, calls to poison centers skyrocketed from just four in 2009 to over 110 in the last year.
The legal loophole of these products is that most of them are sold as "incense" and the packaging often warns that it's "not for consumption."
The synthetic drugs, popular amongst teens around the country, have been known to lead to severe side effects including acute renal failure and even death.
