Synthetic marijuana harms the kidneys
Researchers have found another potential danger to the list: kidney damage. Last year, 16 people found themselves in the ER after using synthetic marijuana and suffering from severe kidney problems.
All of those who suffered from kidney problems were males aged 15 to 33, and most experienced nausea, vomiting and abdominal or back pain. None had any history of kidney disease, and the incidents were reported from six states.
Synthetic marijuana is a mixture of chemicals and herbs, and it is often smoked. Sold as K2, Spice and fake weed, it was officially declared illegal in the U.S. last year. People who use it have similar experiences to using marijuana, though the risk of heart problems is greatly increased, and many users experience hallucinations.
