For the past eight years I have been the patron of a charity called Supporting Wounded Veterans, which helps veterans who have suffered life-changing injuries. We wanted to make it acceptable for soldiers to talk about mental health and to ask for help. MDMA doesn’t produce hallucinations. In March, the US Department of Defense awarded $9.8 million for MDMA research, including studies with active-duty troops. It should recategorise MDMA for research purposes to enable trials to happen faster and at vastly reduced cost.
