Association of MDMA/ecstasy and other substance use with self-reported sexually transmitted diseases among college-aged adults: a national study.

Wu, L-T; Ringwalt, CL; Patkar, AA; Hubbard, RL; Blazer, DG (Public health, 2009-08-04)

MDMA/ecstasy use among college students has increased and reportedly leads to risky sexual behaviours. However, little is known about its association with sexually transmitted diseases (STDs). To evaluate this public health ...

The variety of ecstasy/MDMA users: results from the National Epidemiologic Survey on alcohol and related conditions.

Wu, Li-Tzy; Parrott, Andy C; Ringwalt, Christopher L; Yang, Chongming; Blazer, Dan G (The American journal on addictions, 2009-11)

This study investigates the potential heterogeneity of ecstasy or MDMA (3,4-methylenedioxy-N-methylamphetamine) users. Data came from the 2001-2002 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). ...

The high prevalence of substance use disorders among recent MDMA users compared with other drug users: Implications for intervention.
