Nick Carter says easing controls on MDMA will allow drug to be used as alternative treatment for those with PTSD

A former head of the British military is calling for the government to ease restrictions on the party drug MDMA so that it can be tested more cheaply as a treatment for veterans with post-traumatic stress disorder (PTSD).

Sir Nick Carter, who was chief of the defence staff until 2021, said existing regulations meant a single gram of “medical grade” MDMA cost about £10,000 compared with a street price of about £40, inflating the cost of trials.
