Prospective associations of psychedelic treatment for co-occurring alcohol misuse and posttraumatic stress symptoms among United States Special Operations Forces Veterans.

This study evaluated prospective associations of ibogaine and 5-MeO-DMT treatment for risky alcohol use and post-traumatic stress disorder (PTSD) symptoms among United States (US) Special Operations Forces Veterans (SOFV). Data were collected during standard clinical operations at pre-treatment and 1-month (1 m), 3-months (3 m), and 6-months (6 m) post-treatment in an ibogaine and 5-MeO-DMT treatment program in Mexico. Of the 86 SOFV that completed treatment, 45 met criteria for risky alcohol use at pre-treatment (mean age = 44; male = 100%; White = 91%). There was a significant reduction in alcohol use from pre-treatment (M = 7.2, SD = 2.3) to 1 m (M = 3.6; SD = 3.5) post-treatment, which remained reduced through 6 m (M = 4.0; SD = 2.9; p < .001, partial eta squared = .617). At 1 m, 24% were abstinent, 33% were non-risky drinking, and 42% were risky drinkers. At 6 m, 16% were abstinent, 31% were non-risky drinking, and 53% were risky drinkers. There were no differences between responders (abstinent/non-risky drinkers) and non-responders (risky drinkers) in demographics/clinical characteristics. However, there were significant and very large differences between responders and non-responders in PTSD symptom (p < .01, d = -3.26) and cognitive functioning change (p < .01, d = -0.99). Given these findings, future clinical trials should determine whether psychedelic-assisted therapy holds promise for individuals with complex trauma and alcohol misuse who have not been successfully treated with traditional interventions.

Psychedelic research at a crossroads.

There is an urgent need to develop better treatments for mental health conditions that affect one in every eight people in the world. To combat this concern, psychedelic drugs have been combined with psychotherapy and studied in clinical trials in the United States and Europe. Psychedelics are hallucinogenic drugs that alter brain activity and facilitate altered states of consciousness. The proposed benefits of psychedelic-assisted therapy (PAT) include relatively short treatment times and stronger effects compared to other treatments. Although results of trials using MDMA for trauma or psilocybin for depression are promising, PAT is controversial because many questions about its safety and effectiveness are unanswered. This is evident in the recent ruling by the US Food and Drug Administration against the approval of MDMA therapy for post-traumatic stress disorder and the retraction of several papers about MDMA trials owing to unethical conduct by study therapists and data integrity, among other concerns. This field is at a crossroads, and the research community must address several obstacles to transition from exploratory trials to established, evidence-based treatments while avoiding pitfalls that can hinder advancement.

The Epidemiology of Psychedelic Use Among United States Military Veterans.

We sought to identify patterns of psychedelic use among United States military veterans, compare demographic variables and perspectives of those who did and did not report use, and characterize benefits and adverse outcomes associated with use. Respondents (N = 426) were recruited to complete an online cross-sectional survey. Approximately one-half (51%) reported using psychedelics. Most did so for healing/treatment (70%) and/or spiritual purposes (48%), and most (85%) reported benefiting from use. Those who used psychedelics reported they would be more likely to use VA services (p < .001, d = 0.64) and to return to the VA for care (p < .001, d = 0.79) if psychedelic therapy was offered. Almost two-thirds (59%) reported adverse outcomes associated with use. Equivalent proportions rated their psychedelic experiences as beneficial among those who did (89%) and did not (81%) report adverse outcomes. Fewer adverse outcomes were associated with being older, using psilocybin, feeling prepared and confident in the reasons for use, being in a comfortable setting, and being able to "trust, let go, and be open" (Rc = 0.77; p < .001). Psychedelics may offer benefits but may also lead to adverse outcomes without proper preparation and support. Future research should examine the utility of psychedelic-based approaches for veteran mental health care.

Study protocol of an open-label proof-of-concept trial examining the safety and clinical efficacy of psilocybin-assisted therapy for veterans with PTSD.

INTRODUCTION: Psilocybin-assisted therapy has shown significant promise in treating the cluster of mood and anxiety symptoms that comprise post-traumatic stress disorder (PTSD) but has yet to be tested specifically in this condition. Furthermore, current pharmacological and psychotherapeutic treatments for PTSD are difficult to tolerate and limited in efficacy, especially in the US Military Veteran (USMV) population. This open-label pilot study will examine the safety and efficacy of two psilocybin administration sessions (15 mg and 25 mg), combined with psychotherapy, among USMVs with severe, treatment resistant PTSD. METHODS AND ANALYSIS: We will recruit 15 USMVs with severe, treatment resistant PTSD. Participants will receive one low dose (15 mg) and one moderate/high dose (25 mg) of psilocybin in conjunction with preparatory and post-psilocybin therapy sessions. The primary safety outcome will be the type, severity and frequency of adverse events and suicidal ideation/behaviour, as measured by the Columbia Suicide Severity Rating Scale. The primary outcome measure for PTSD will be the Clinician Administered PTSD Scale-5. The primary endpoint will be 1 month following the second psilocybin administration session, and the total follow-up time will be 6 months. ETHICS AND DISSEMINATION: All participants will be required to provide written informed consent. The trial has been authorised by the Ohio State University Institutional Review Board (study number: 2022H0280). Dissemination of results will occur via a peer-reviewed publication and other relevant media. TRIAL REGISTRATION NUMBER: NCT05554094.

Bouncing back from COVID-19: The role of resilience in depression, substance use, and loneliness in college students amidst the pandemic.

Objective: To assess the influence of specific COVID-19 impacts on college student depression, loneliness, and alcohol and cannabis use, and to investigate if resilience moderates these relationships. Participants: Data were collected from students (N = 1849, 80.9% white, 66.6% female) at a midwestern university during the 2021 winter/spring semester. Methods: Data were gathered cross-sectionally through an online survey platform. COVID-19 impacts and resilience's relationships with mental health variables were analyzed with multiple regression analysis. Moderation analyses were conducted using PROCESS. Results: The COVID-19 impacts measured in this study were significantly related to student depression and cannabis use. Resilience moderated the association between COVID-19 impacts and (a) depression and (b) cannabis use. Conclusion: Resilience may mitigate the effect of pandemic-related impacts on depression and cannabis use in college students, but not loneliness and alcohol use. These findings hold important implications for further research and practice.
