It's been more than 50 years since the United States dropped the atomic bomb on Japan. To this day, Americans know very little about how that decision was reached. Did it shorten the war? Did it save American lives? Was it necessary? Were there alternatives? Did the United States need to be the first and the only nation to use an atomic bomb?

In the 1990s, Ecstasy seemed to come out of nowhere to join marijuana, cocaine and heroin as one of the four most widely used illegal drugs in the country. No other drug has ever spread so fast. To halt its spread, the U.S. Government has spent millions of dollars making a dramatic case against Ecstasy as a dangerous drug. The headline of this campaign has been that Ecstasy causes massive brain damage. But this is a claim based on flawed science, and many Ecstasy users now feel their government has no credibility. What do we know about the real risks of Ecstasy? Has the government been its own worst enemy in the fight to stop the drug's use? Peter Jennings Reporting: 'Ecstasy Rising' takes viewers through the seminal events in this story and introduces all the major players -- from Alexander Shulgin, the famous chemist who was the first person to report the effects of Ecstasy, to Michael Clegg, the Dallas businessman who gave Ecstasy its name and turned it into a recreational drug, to the drug enforcement officer who led the fight to make Ecstasy illegal, to the DJ who brought Rave to America.
