Synthetic stimulants called 'bath salts' act in the brain like cocaine
Date:7/23/2012

CHAPEL HILL, NC The use of the synthetic stimulants collectively known as "bath salts" have gained popularity among recreational drug users over the last five years, largely because they were readily available and unrestricted via the Internet and at convenience stores, and were virtually unregulated.

Recent studies point to compulsive drug taking among bath salts users, and several deaths have been blamed on the bath salt mephedrone (4-methylmethcathinone or "meow-meow"). This has led several countries to ban the production, possession, and sale of mephedrone and other cathinone derivative drugs.

In October 2011, the U.S. Drug Enforcement Administration placed mephedrone on Schedule 1 of the Controlled Substances Act for one year, pending further study. "Basically, the DEA was saying we don't know enough about these drugs to know how potentially dangerous they could be, so we're going to make them maximally restricted, gather more data, and then come to a more reasoned decision as to how we should classify these compounds," said C.J. Malanga, MD, PhD, associate professor of neurology, pediatrics and psychology at the University of North Carolina School of Medicine. He is also a member of the UNC's Bowles Center for Alcohol Studies.

Now, results of a new study led by Malanga offer compelling evidence for the first time that mephedrone, like cocaine, does have potential for abuse and addiction. "The effects of mephedrone on the brain's reward circuits are comparable to similar doses of cocaine," he said. "As expected our research shows that mephedrone likely has significant abuse liability."

A report of the study was published online on June 21, 2012 by the journal Behavioural Brain Research. The report's first author and MD/PhD student at UNC J. Elliott Robinson points out that mephedrone and other potentially addictive stimulants "inappropriately activate brain reward circuits that are involved in positive rei
