ABC News television documentary with Peter Jennings on the history of MDMA (3,4-methylenedioxy-N-methylamphetamine) also known as ecstasy. It includes a short history of the drug and criticizes the negative health claims made by the U.S. government. The rise of Ecstasy is a major event in drug history. If current trends continue, 1.8 million Americans will try Ecstasy for the first time in 2004. Only marijuana will attract more new users. Overwhelming, positive word of mouth has made Ecstasy a nightmare for drug controllers. On a special edition of 'Primetime Thursday' Peter Jennings tells the epic story of Ecstasy that has never been heard.
