Could a tiny dose of LSD help adults with ADHD?
NCT ID NCT05200936
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether repeated low doses of LSD (called MM120) can safely help adults with ADHD. Fifty-three adults took either the drug or a placebo, and researchers measured changes in ADHD symptoms using a standard rating scale. The goal was to see if this approach could be a new way to manage ADHD without needing daily medication.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
LSD (lysergic acid diethylamide) as a low-dose tartrate salt (MM120)
What this could lead to
If it works, this could point toward a new, non-daily medication option for managing ADHD symptoms in adults.
What could go wrong
This is a small, early-phase proof-of-concept trial with only 53 participants. The psychedelic effects of LSD may cause hallucinations or other side effects, and it is not yet proven effective or safe for ADHD.
