Then there's this, indeed, anyone looking into medical use of marijuana and its derivatives, should be sure of their provenance. Always work with supervision from a health professional, imho.
(CNN) A drug called K2 is believed to be behind more than 100 overdoses in New Haven, Connecticut, this week. Some of those who overdosed experienced speeding heart rates, difficulty breathing and vomiting. Others were found collapsed in a semiconscious or unconscious state on the New Haven Green, the downtown park.
Although no deaths were reported, two people experienced serious, life-threatening consequences. Earlier this year, K2 was also tied to 56 cases of severe bleeding, including four deaths, across Chicago and central Illinois. In a separate incident, 33 people collapsed on the streets of New York City. A
July report from the US Centers for Disease Control and Prevention indicated that the number of K2 poisonings rose sharply over the past year.
So what is this drug that is causing all this mayhem?

'A different animal altogether'
"The nomenclature 'synthetic marijuana' is really incorrect. These things are not synthetic marijuana, and I worry using this term might give the wrong impression, especially to young people," said Mike Baumann, chief of the Designer Drug Research Unit at the National Institute on Drug Abuse.
K2 or "spice" is a mixture of herbs, spices or shredded plant material that has been sprayed with chemicals that are similar to but not the same as THC, the psychoactive ingredient in marijuana. Sometimes, K2 comes in liquid form to be vaporized in e-cigarettes. It is also smoked in joints or pipes or made into a tea.
