Among people who used 5-MeO-DMT in a structured group setting with guided dosing and support, 80% of those previously diagnosed with depression and 79% of those previously diagnosed with anxiety reported their condition improved after use. Only 3% with depression and 2% with anxiety said their condition worsened. Greater improvement was linked to more intense mystical experiences and higher ratings of the experience's spiritual significance and personal meaning, but not to the intensity of challenging physical or psychological effects. The findings suggest potential therapeutic benefits, warranting controlled clinical trials.

A survey of 515 adults who use 5-MeO-DMT found that consumption is infrequent and associated with profound positive subjective effects, including perceived spiritual and personal growth. Motivations for use were primarily spiritual and recreational, and many respondents reported perceived benefits consistent with potential psychotherapeutic effects. The study provides initial epidemiological data on usage patterns and subjective experiences with this psychoactive tryptamine.

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.
