Psilocybin has been shown to have low physiological toxicity (i.e., limited negative impacts on physical health) and low abuse potential when orally ingested (35,36). The psychedelic effects of hallucinogenic drugs may help ease the effects of trauma, but research so far has produced mixed results. Some of the compounds that practitioners most frequently use in this form of treatment include psilocybin mushrooms, LSD, and mescaline (peyote). “This is particularly important when these agents are obtained ‘on the street.’ These days, just about any street drug can be contaminated with fentanyl, a highly potent, often deadly opioid. The sooner we move toward legalization and regulation of these agents at a federal level, the better off we will be in terms of quality control,” Peters said.
Translational neuropsychopharmacology describes utilizing human neuroimaging techniques specifically in the development of novel psychopharmacological interventions for psychiatric populations. Neuroimaging provides researchers with unparalleled insight into the pathobiology of disorders such as addiction, allowing for the identification of putative functional and molecular biomarkers. These tools are also used to assess the effects of novel interventions, such as psychedelics, on addiction biomarkers and their relationship with clinical and behavioral outcomes. Over 1000 papers were published during the mid-late twentieth century describing the treatment of 40,000 patients with a psychiatric disorder, including addiction, with classic psychedelics, especially LSD (14).
The reasons for a lack of access to adequate services are multifactorial and are reported eminently in the UK government-commissioned independent review of drugs from August 2021 by Dame Carol Black (9). Her report furthers the calls from NIDA’s 2019 medication development priorities paper, highlighting the pressing socio-economic need for the development of more effective treatments through innovative and mechanistic scientific programs to improve translation to the clinic (10). When classical psychedelics were used, one study had inconclusive results and two reported improved quality of life, but the evidence is very uncertain. Psychedelics remain an experimental treatment, and not something someone can get as a matter of course in their doctor’s office or in therapy.
Particularly hyper- and hypo-activations of salience, attentional, executive, and memory networks have been observed in response to addiction-salient versus naturally rewarding or non-salient video and photo cues (78). Greater responses to addiction-related stimuli and craving are observed in patients with addiction and this represents aberrant incentive sensitisation which is theorized to lead to maladaptive drug-taking behaviors (93). Cue-reactivity fMRI has also shown utility in being able to predict addiction severity, risk of relapse and treatment outcome (95) and has been leveraged to develop novel therapeutics in addiction (96). To date, there have been no published literature relevant to cue-reactivity in addiction populations being treated with psychedelic therapy. Hence, fMRI cue-reactivity paradigms provide an ideal platform to assess the neurobiological effects of psychedelic therapy on reward and motivational systems in addiction. Integration of fMRI cue-reactivity paradigms into clinical studies in a pre- vs. post-psychedelic design is recommended to assess changes in brain function and its association with craving and longer-term clinical outcomes, such as relapse.
Today, a growing number of studies suggest the Alcoholic Anonymous co-founder’s revelation might be right. The association also welcomes questions or concerns about psychedelic-assisted therapy, and can make recommendations to help guide you. Otherwise, psychedelic substances are generally considered low risk, especially when used in a clinical setting. Experts believe it could also help with obsessive-compulsive disorder, addiction, and treatment-resistant depression, but more research is needed.
Several novel agonist radiotracers including 11CPHNO have been found to be sensitive to endogenous dopamine (167). Utilizing this radiotracer in a multimodal fMRI-PET study with behaviorally salient, dopamine-enhancing tasks such as monetary reward paradigms, that probe addiction-related brain processes, could theoretically release dopamine in the living buy lsd vial liquid human brain. The extent to which psychedelic therapy remediates the observable neurotransmitter and functional deficits and their relationship to clinical outcomes would offer unparalleled insight into this intervention. This would provide evidence for the ‘molecular-functional-clinical’ translational explanatory bridge, which so far in psychiatric psychopharmacology research has not been conducted, and would provide the most advanced biopsychosocial theory of psychedelics in treating addiction.
