“Synthetic cannabinoids are not marijuana,” the head of the city's poison control center told the Patch. “They are unique drugs made in a lab that have one effect in common with marijuana but potentially many other different effects. They are sold as herbal products, giving users a perception of safety, but in fact they are toxic drugs sprayed on plant leaves.”
The Brooklyn Paper reported on the stuff a few months ago, when it was still legal. “I felt way, way too high, my entire body and insides hurt, and I couldn’t breathe,” one user said. “I started getting too hot and took off my shirt and my tank top even though it was freezing out.” Another reported that "his vision blurred, his memory lapsed and 'everything was glistening,' while his girlfriend suffered a panic attack."
