Substance Use Disorders (SUD)

Addiction is one of the oldest hopes for psychedelic medicine, going back to LSD trials for alcoholism in the 1950s. Today psilocybin is the workhorse, with positive trials in alcohol, tobacco and cocaine use disorders, and the cross-substance signal is real. But the picture is mixed rather than settled: a major alcohol trial was null, the studies are small, and almost all of them struggle to keep patients unaware of whether they got the drug. This page is the hub; alcohol, opioid and tobacco use disorders have their own dedicated pages.

5-Methoxy-N,N-dimethyltryptamine (5-MeO-DMT) for alcohol use disorder: An open-label, phase 2, proof-of-concept, clinical trial

In an open‑label Phase IIa trial (n-12), a single 10 mg intranasal dose of 5‑MeO‑DMT (BPL‑003) given alongside a 10‑week relapse‑prevention CBT programme was acceptable in safety and tolerability in people with moderate–severe alcohol use disorder. Over 12 weeks, participants showed large improvements in drinking (mean abstinent days rose from 33.2% to 80.8% and heavy drinking days fell from 56.2% to 13.2%), providing preliminary evidence of efficacy and supporting larger controlled trials.

Mapping the phenomenology of intranasal 5-MeO-DMT in psychedelic-naïve healthy adults

This Phase I double-blind placebo-controlled trial (n=32) using microphenomenology interviews found that intranasal 5-MeO-DMT produced dose-dependent subjective effects with rapid onset peaking at 8-15 minutes and return to baseline by 45-60 minutes, characterised by minimal visual effects but strong emotional and bodily experiences, including emotional breakthroughs and personal insights.

Complex slow waves in the human brain under 5-MeO-DMT

This naturalistic EEG study (n=29) examines the effects of inhaled synthetic 5-MeO-DMT (12mg) on brain activity in healthy individuals. It finds that 5-MeO-DMT radically reorganises low-frequency neural activity flows, making them incoherent, heterogeneous, and nonrecurring. It also causes broadband activity to exhibit slower, more stable, low-dimensional behaviour with increased energy barriers to rapid global shifts.

Health-related behavioral changes following the use of psychedelics in naturalistic settings

This cross-sectional study (n=2,510) of US adults with psychedelic experience found that participants retrospectively reported widespread improvements in health behaviours including reduced alcohol (66%) and tobacco (49%) use, better dietary habits (49%), and decreased impulsivity (48-72%), with microdosers and frequent users showing greater positive changes.

Safety and tolerability of multiple sublingual microdoses of 5-MeO-DMT in adults with moderate symptoms of depression and/or anxiety: a randomized, double-blind, placebo-controlled study

This Phase I clinical trial (n=36) of sublingual 5-MeO-DMT (6-12 mg weekly doses over four weeks) in adults with moderate to high anxiety/depression demonstrated good safety and tolerability with no significant adverse events, rapid absorption with peak plasma concentrations at 20 minutes, dose-dependent neurophysiological modulation without full psychedelic effects, and maintenance of normal cognitive and behavioral function.

Psilocybin-assisted therapy for relapse prevention in alcohol use disorder: a phase 2 randomized clinical trial

This double-blind randomised clinical trial (n=37) found that a single dose of psilocybin (25mg) with brief psychotherapy did not significantly reduce alcohol relapse rates or consumption compared to placebo in patients with alcohol use disorder (AUD) at 4-week or 6-month follow-up, though psilocybin participants reported additional reductions in craving and temptation to drink, suggesting larger trials are needed to evaluate this approach for severely affected patients.
