What are the functionalist, conflict and symbolic interactionist perspective on ecstasy use in America?

In the U.S., MDMA was legal and unregulated until May 31, 1985, at which time it was emergency scheduled to DEA Schedule I, for drugs deemed to have no medical uses and a high potential for abuse. During DEA hearings to schedule MDMA, most experts recommended DEA Schedule III prescription status for the drug, due to beneficial usage of MDMA in psychotherapy. The judge overseeing the hearings, Francis Young, also recommended that MDMA be placed in Schedule III. Nevertheless, the DEA clified MDMA as Schedule I.[68][69] In 2001, responding to a mandate from the U.S. Congress, the U.S. Sentencing Commission, resulted in an increase in the penalties for MDMA by nearly 3,000%,[70] despite scientific protest calling for a decrease in the penalties for MDMA possession and distribution.[71] The increase makes 1 gram of MDMA (four pills at 250 mg per pill's total weight regardless of purity, standard for Federal charges) equivalent to 1 gram of heroin (approximately fifty doses) or 2.2 pounds (1 kg) of marijuana for sentencing purposes at the federal level.[72] See also the RAVE Act of 2003.
