ADHD (Attention-Deficit/Hyperactivity Disorder) affects millions of adults worldwide, with stimulants like methylphenidate and amphetamine being the most effective treatments. But could psychedelics like LSD offer an alternative? A new randomized clinical trial aimed to find out.
👉 Study Overview:
- Design: Multicenter, double-blind, placebo-controlled trial (N = 53)
- Participants: Mean age 37 years, 42% female
- Intervention: Low-dose LSD (20 μg) or placebo twice weekly for 6 weeks (12 doses total)
- Primary Outcome: Change in ADHD symptoms using the Adult ADHD Investigator Symptom Rating Scale (AISRS)
💡 Key Findings:
- Both groups showed significant improvement in ADHD symptoms:
- LSD group: −7.1 points (95% CI, −10.1 to −4.0)
- Placebo group: −8.9 points (95% CI, −12.0 to −5.8)
- ✅ LSD was safe and well tolerated
- ❌ No significant difference between LSD and placebo in symptom reduction
🧠 What This Means:
While low-dose LSD was safe, it didn’t outperform placebo in treating ADHD symptoms. This challenges anecdotal claims about psychedelics for ADHD and reinforces the need for rigorous placebo-controlled trials in psychedelic research.
📈 Future research may explore higher doses or alternative mechanisms—but for now, stimulants remain the gold standard for ADHD treatment.
