Effects of MDMA: "Ecstasy's effects last 3 to 6 hours. It is a mood elevator that produces feelings of empathy, openness and well-being. People who take it at all night "rave" dances say they enjoy dancing and feeling close to others. It does not produce violence or physical addiction."
Initiation of MDMA Use in the US: There were 839,000 past year initiates of Ecstasy aged 12 or older in 2015 (Figure 10), which averages to about 2,300 people each day who initiated Ecstasy use. In 2015, an estimated 168,000 adolescents aged 12 to 17 (Table A.8A in Appendix A), 531,000 young adults aged 18 to 25 (Table A.9A), and 141,000 adults aged 26 or older (Table A.10A) used Ecstasy for the first time in the past year. In 2015, the average age at first Ecstasy use among recent Ecstasy initiates aged 12 to 49 was 20.7 years (Figure 11).
Prevalence and Trends in LSD Use Among Young People in the US: "Past-year use of LSD, one of the major drugs in the hallucinogen class, has been hovering for about a decade at its lowest levels recorded by the study (Figure 5-4e). In 2015 the levels of use for students in 8th, 10th, and 12th grade were 0.9%, 2.0%, and 2.9%, respectively. Consistent with most other drugs, use increased during the 1990s relapse and peaked in the mid-1990s. It then subsequently declined to its lowest levels ever in the early 2000s, where it has since plateaued.

On-Site Pill Testing and Harm Reduction: "Pill testing interventions are important measures to enter into contact with hard-to-reach populations and to raise their interest in preventive and harm reduction messages."
MDMA (Ecstasy or Molly) and Cognitive Impairment: "In summary, our data suggest that ecstasy use over a period of months or a few years may cause long term impairment of cognitive performance even when ecstasy is taken in typical recreational and not necessarily very high doses."
MDMA and Treatment of Trauma and PTSD in US: In 2004, the Drug Enforcement Administration gave permission for the first US trial of MDMA for use in treating trauma: "Capping a 17-year effort by a small but committed group of activists, the federal Drug Enforcement Administration has agreed to let a South Carolina physician treat 12 trauma victims with the illegal street drug ecstasy in what will be the first U.S.-approved study of the recreational drug's therapeutic potential.
