Vaporized 5-MeO-DMT, a psychoactive substance from the Colorado River Toad, reliably produced strong mystical experiences in 20 individuals at a psychospiritual retreat. Participants received 50 mg of inhaled bufotoxin and completed the Mystical Experience Questionnaire. The average intensity was 4.17 out of 5, and 75% had a complete mystical experience. Compared to a prior psilocybin study, 5-MeO-DMT matched the intensity of a high dose (30 mg/70 kg) of psilocybin and significantly exceeded a moderate/high dose (20 mg/70 kg). The short duration may benefit clinical interventions and research on mystical-type experiences.

Ibogaine, a plant-derived compound, reduces opioid withdrawal and craving during detoxification. In 50 participants with opioid use disorder undergoing a week-long ibogaine treatment protocol, withdrawal and craving scores were significantly lower 48 hours after administration compared to baseline. At that point, 78% showed no objective clinical signs of opioid withdrawal, 79% reported minimal cravings, and 68% reported only mild subjective withdrawal symptoms. The findings suggest ibogaine can facilitate opioid detoxification by easing withdrawal and craving, but controlled trials are needed to confirm these results.

A survey of 88 patients who received ibogaine treatment in Mexico between 2012 and 2015 found that most (80%) reported the drug eliminated or drastically reduced withdrawal symptoms, and half said it reduced opioid craving, with some reporting that reduction lasting at least three months. Thirty percent never used opioids again after treatment, and over half of those abstainers had been abstinent for at least one year. Although 70% relapsed, 48% decreased use from pretreatment levels and an additional 11% eventually achieved abstinence. Treatment responders had lower rates of depressive and anxious symptoms and higher well-being. The results suggest ibogaine is associated with reductions in opioid use and improved psychological outcomes.

A 31-year-old male military veteran with moderate alcohol use disorder received sequential treatment with ibogaine hydrochloride (1550mg, 17.9mg/kg) on day 1 and vaporized 5-MeO-DMT (bufotoxin source 50mg, estimated 5-7mg) on day 3 at an inpatient clinic in Mexico. SPECT neuroimaging before and 3 days after treatment showed increased brain perfusion in bilateral caudate nuclei, left putamen, right insula, and temporal, occipital, and cerebellar regions. The patient reported improved mood, cessation of alcohol use, and reduced cravings at 5 days, sustained at 1 month, with partial return to mild alcohol use at 2 months. The findings suggest short-term therapeutic outcomes and warrant further investigation.

Most people who underwent ibogaine detoxification for chronic opioid use reported lasting positive changes, including enhanced gratitude, authenticity, and appreciation for life. Those who responded well to treatment showed greater improvements in tolerating difficult feelings, coping with stress, reduced unhealthy anger, and increased inner peace, joy, love, and a sense of sacredness in life. They also reported heightened spiritual awareness and stronger connections in relationships. Challenges included psychological and health difficulties during treatment and problems with post-treatment integration. The findings point to the need for more integration and aftercare resources. Further rigorous experimental research is needed.

People who took ibogaine for opioid use disorder reported a powerful experience that reduced withdrawal and craving and led to a more optimistic outlook on self and life. Participants described subjective neurological and physical effects, auditory and visual phenomena, and shifts in their perspective. The treatment attenuates opioid withdrawal and produces a subjectively intense physiological, emotional, and psychological experience.

Among 45 U.S. Special Operations Forces Veterans with risky alcohol use who completed ibogaine and 5-MeO-DMT treatment in Mexico, alcohol use dropped substantially from an average of 7.2 drinks per drinking day before treatment to 3.6 at one month and 4.0 at six months post-treatment. At one month, 24% were abstinent, 33% were non-risky drinkers, and 42% still risky drinkers; by six months, 16% were abstinent, 31% non-risky, and 53% risky. Responders (abstinent or non-risky) showed very large improvements in PTSD symptoms and cognitive functioning compared to non-responders, while demographics did not differ. The findings suggest psychedelic-assisted therapy may help those with complex trauma and alcohol misuse who have not responded to traditional treatments.
