'Synthetic drugs are anything but harmless, and this rash of severe health emergencies across the state is direct proof,' Governor Cuomo said, according to The Hudson Valley News Network. 'We banned synthetic marijuana, bath salts and similar substances to avoid the disastrous results that occur – and as law enforcement and health officials continue to crack down on the use and sale of these drugs in New York, we are today issuing a health alert as a warning amidst this surge in hospitalizations.' Symptoms can range from confusion, drowsiness and headaches to increased heart rate, seizures and loss of consciousness, according to the New York State Department of Health.

Synthetic marijuana a mix of herbs that has been sprayed with a chemical to produce a similar sensation to traditional marijuana. 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. Two of these Mississippi cases were Jeff and Joey Stallings, brothers who were hospitalized April 6 after smoking Spice. The siblings, both in their twenties, fell seriously ill  after smoking the drug, which is a mix of herbs that has been sprayed with a chemical to produce a similar sensation to marijuana. 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.

'He gave into (peer pressure) - thinking that it was okay, it was somehow safe - and one hit later, he goes to sleep and never wakes up,' Connor’s father, Devin Eckhardt told KTLA at the time. Doctors were unable to detect spice in Connor's system - there is no way to trace its everchanging components. However, they knew he had taken it after finding the package of the drug in his pocket. Connor's family donated his organs after his death, in accordance with the teenager's wishes. They later created a Facebook page to warn others about the perils of synthetic marijuana.
