MDMA, the key ingredient in the illegal party drug ecstasy, may soon be approved as a medicine. Meanwhile, it's also making a comeback across Europe's clubs and music festivals.

Manuela Saragosa speaks to neuropharmacologist David Nutt of Imperial College, who once got fired by the UK government for saying MDMA was less dangerous than horse-riding, and with psychedelic psycho-therapist Rick Doblin, who is seeking to get the chemical approved for the treatment of PTSD.

But while the drug may be safe in a clinical setting, dozens of people still die each year from taking illicit ecstasy pills. We hear from Andrew Cunningham of the EU drugs agency EMCDDA, and from Fiona Measham of the illegal drugs-testing service, The Loop.
