The majority of club drug users are multiple drug users, according to a recent analysis of data from the 2002 National Survey on Drug Use and Health. 

Overall, 20% of youths and young adults ages 16 to 23 reported ever using at least one or more of the club drugs methamphetamine, MDMA, LSD, GHB, ketamine, or flunitrazepam.

Nearly one-fifth (17%) of these lifetime club drug users reported using two different types of illicit drugs and 82% reported using three or more different types of drugs in their lifetime.

Users of GHB, ketamine, flunitrazepam, and methamphetamine were most likely to be multi-drug users -- between 96% and 100% reported have ever used three or more types of illicit drugs.

These findings are consistent with those of a study of multiple drug use among Maryland public high school students, which found users of less common drugs were more likely to use multiple drugs.
