Initiation of MDMA Use in the US

"As noted previously, estimates of Ecstasy initiation in 2015 are not compared with estimates from prior years because of the addition of “Molly” as a slang term for Ecstasy in 2015. 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)."
