Ecstasy trials for combat stress

From society.guardian.co.uk:

American soldiers traumatised by fighting in Iraq and Afghanistan are to be offered the drug ecstasy to help free them of flashbacks and recurring nightmares.

The US food and drug administration has given the go-ahead for the soldiers to be included in an experiment to see if MDMA, the active ingredient in ecstasy, can treat post-traumatic stress disorder.

The South Carolina study marks a resurgence of interest in the use of controlled psychedelic and hallucinogenic drugs. Several studies in the US are planned or are under way to investigate whether MDMA, LSD and psilocybin, the active ingredient in magic mushrooms, can treat conditions ranging from obsessive compulsive disorder to anxiety in terminal cancer patients.
