"It is clear that consumers are buying products that they think contain specific substances, but that in reality the labels are unreliable indicators of the actual contents," Dr. Mark Baron, of the School of Natural and Applied Sciences at the University of Lincoln in England, said in a news release from the journal's publisher.

The investigators found that these drugs, sometimes marketed as bath salts or plant food, commonly contain controlled substances and are being sold illegally.
