ABC News:
The sale of K2, a once-legal but potentially dangerous form of synthetic marijuana, is now banned nationwide.
The ban, proposed in November 2010 amid increasing reports of seizures, hallucinations and dependency linked to the fake pot, was "necessary to prevent an imminent threat to public health and safety," according to the Drug Enforcement Administration. It has now banned
K2 and five chemicals used to make it.
K2 was sold openly in head shops and online as incense. It largely avoided regulation in the United States because it was sold in packages that stated it was not for human consumption.
Little is known about the long-term effects of the fake pot, also known as Spice, Demon, Genie, Zohai and a host of other names. But its short-term effects, which include soaring heart rates and paranoia, have landed some of those who smoked it in the hospital.
