ABSTRACT
Recreational use of MDMA has been on the rise for the past 20 years (Peroutka, 1987; Schuster et al., 1998; Pope et al., 2001). Increases in the rate of MDMA use have continued despite reductions in the use of other substances (Johnston et al., 2001a,b). This is an international trend (Abraham et al., 1998; Hibell et al., 2000; McPherson and Afsarifard, Chapter 3 of this book).
