Synthetic pot is sending more teenagers to the emergency room, according to a new study. Synthetic pot is mixture of plants and herbs, commonly known as "K2" or "Spice."
The American Association of Poison Control Centers says the number of calls more than doubled in 2011.
The latest edition of the journal Pediatrics, doctors highlighted three case studies of teenagers who came to the emergency room to be treated for synthetic pot.
The Drug Enforcement Administration banned the spice more than a year ago. However, makers of the product changed some of the ingredients to make it legal.
ABC2 News first reported on the problems of synthetic pot in 2011. We developed a Synthetic Drug Resource Guide, which helps you identify the symptoms of someone who's ingested synthetic pot.
