For nearly 30 years, there has been a steady flow of research papers highlighting the dangers of MDMA and the implications for ecstasy users. After such a long time, it would be reasonable to expect that these dangers would be obvious due to the large number of ecstasy users. The available evidence does not indicate that there are millions of ecstasy users experiencing any problems linked to...

National drugs information strategies convey the message that use of Ecstasy is associated with an increase in both the incidence and severity of major depressive disorder. However, very little primary research supports this.

Abstract In the late 1970s and early 1980s considerable publicity was given to the use of hypnosis as a technique to facilitate witness' memory in police investigations. As empirical evidence mounted, however, a number of limitations and disadvantages emerged with regard to the use of hypnosis in this role. As a consequence, hypnosis as an aid in forensic investigations is now treated with...
