Resources

This page lists the primary sources behind our reporting, plus organisations that can help if you are considering treatment. We link to the original trial records, peer-reviewed papers and government guidance rather than to news summaries wherever possible, so you can check what a study actually said.

• MDMA-assisted prolonged exposure therapy for comorbid alcohol use disorder and PTSD — trial listing

How we use these sources

Every research article on this site links to the study or official announcement it is reporting. Where a finding is preliminary, we say so in the headline or the opening paragraph. Where a claim is disputed — and the MDMA evidence base is heavily disputed — we present both readings rather than picking a side.

We do not publish dosing instructions, we do not recommend obtaining MDMA outside a legal route, and we do not accept advertising from clinics offering the treatment. Our guides are written for people who want to understand the research and the regulations, not for people looking for a source.
