If a new drug emerges on the streets, it has been predicted that it will become established in a deviant population before being diffused to members of the general population. This study was the first to address the problem of ecstasy use among adult criminal justice populations. Data collection methods are described by the author and results are given in a table of 2 day self-reported ecstasy use by ADAM geographical site, 2000. It was found that the use of ecstasy by adult male ADAM arrestees was virtually non-existent, less than 1.0 percent in a high majority of ADAM sites. It is noted that one study has been done on the use of ecstasy by juvenile arrestees, reporting usage by 8 percent within the 30 days prior to the interview. The advantages of the ADAM data collection of drug use in the United States are reviewed. In conclusion, it is recommended that further research should continue in the area of drug diffusion, with the knowledge that diffusion does not necessarily move from deviant to non-deviant populations.
