It is nicknamed Spice, Mojo, K2, Yucatan Fire, Solar Flare and Bliss, among other things. The drug is typically smoked by users. It does not give positive results in tests for cannabis. Because the herbs and chemicals in synthetic marijuana vary, it is impossible for users to know what they are smoking. They also cannot tell what concentrations they are taking - which can lead to fatal overdoses. Unlike pot, Spice can cause a huge range of symptoms, many of which can be severe. These include tremors, paranoia, seizures, vomiting, hallucinations, chest pain, cardiac problems, kidney damage and brain damage. Meanwhile in Mississippi, there were 97 cases over eight days in April, according to CNN.

They were hospitalized within hours of each other, when they collapsed after suffering from hallucinations, vomiting, night sweats and violent shaking. They had to be put on life support. Fortunately both were able to fight for their lives and were allowed home on April 13. Jeff Stallings, however, has suffered permanent kidney damage.
