Psychedelics: entering a new age of addiction therapy

The aim of this review is to examine the current standing of evidence regarding psychedelic psychopharmacology and to provide an overview of the use and effectiveness of these drugs in the treatment of SUD, alcohol use disorder, and for smoking cessation. Low, medium, and high doses were assigned in that order, with a very low dose inserted randomly after the first low dose. Their symptoms were assessed at baseline and again at 1, 7, 14, and 21 days post treatment. None of the patients had any prior use of ayahuasca, and all participants were weaned off their antidepressant medications prior to drug administration. Significant antidepressant effects of ayahuasca were observed when compared with the placebo group from baseline to 7 days after dosing.15 Although results seem promising, the number of participants was small and therefore randomized trials in larger populations are necessary. Psilocybin was administered at a moderate dose, and one week later followed by a high dose.

Schedule I controlled substances

“In six weeks, you get re-scored for depression, and if you meet the criteria then, without anyone knowing what you got in the randomized portion, you become able to be re-dosed in the open label session for a total of four times in the next year,” he said. The state of Oregon is pursuing an alternative model in which trained facilitators licensed by the Oregon Health Authority will administer psilocybin21. Clients seeking access to ‘psilocybin services’, as they are called in Oregon, need not have a medical diagnosis to participate.

Everyone deserves addiction treatment that works — including those in jail

Bogenschutz is emphatic that psychedelics like psilocybin should be used under medical supervision, with trained therapists to prepare patients for experiences “that can be extremely intense and challenging, in some cases.” If there were no adverse reactions, the second psilocybin sessions involved higher doses of both drugs and more therapy. “Methamphetamine, in particular, is posing a huge public health challenge,” he said. “Here in New Mexico and around the country the rates are just going up.” At the moment there are few effective treatments for methamphetamine addiction, he said, but there is hope that ketamine might be a game-changer. “I have an interest because it might be useful in cases where a shorter experience might be more useful,” Leeman said.

Is a governor-appointed member of the Oregon Psilocybin Advisory Board and chairs its licensing subcommittee. Weak psychedelic patents could potentially be invalidated in court, but that does not make them harmless, because patent holders can still wield them offensively.

All four clinical trials indicated a beneficial effect of psilocybin-assisted therapy on SUD symptoms. Larger RCTs in patients with SUDs need to evaluate whether psilocybin-assisted therapy is effective in patients with SUD. FMRI techniques have been developed to probe the neural responses to cognitive and psychological tasks, external stimuli, and pharmacological or behavioral challenges. FMRI measures brain activity via the blood oxygenation level-dependent (BOLD) signal, providing an indirect measure of brain activity that can be examined in response to neurocognitive tasks or at rest. In the context of addiction, several well-validated fMRI paradigms have been developed that assess the neural responses to reward, punishment, salience attribution, emotions, memory, cognitive and executive function and their association with clinical outcomes and relapse vulnerability.

This may take a few days to a week, and it’s often a physically and mentally painful process. Depending on the substance and use severity, inpatient treatment may be essential to keep patients safe during this phase. Earlier this year, the National Institute on Drug Abuse gave a $2.7 million grant to research on psychedelics for addiction.5 As these therapies move from research into clinical practice – it’s essential for more clinicians to be educated in the principles of psychedelic therapy. Psychedelics have certain effects, such as mystical experiences, that make them attractive for recreational use.

The Native American Church have a history of using peyote in the context of ritualized sacramental practices to aid recovery from addiction and substance misuse. Several anthropological studies have documented its use and beneficial anti-addictive effects in these settings in the US (46–48). One retrospective survey in individuals with alcohol and ‘drug use disorders’ found 48 out of 72 with alcohol addiction and 58 of 85 with ‘drug use disorder’ improved following ingestion of mescaline (49). No studies were identified evaluating the efficacy of psilocybin in patients with benzodiazepines or hypnotics, caffeine, cannabis, hallucinogens, ketamine, inhalants or other (or unknown) substances use disorder, nor in patients with a gambling or gaming disorder. No studies were identified evaluating the efficacy of psilocybin in patients with amphetamine (or derivatives) use disorder.

1. His jail became one of the few in the nation to be licensed as an opioid treatment program.
2. At 6.5 months, 60 to 80% of the psilocybin group continued to report improvements in depression and anxiety.
3. Either the MHRA or the European Medicines Agency, also based in London, is responsible for approving drugs for medical use, while the Home Office decides the schedule.
4. However, regulated treatments are currently experimental and not accessible to many people.
5. Many physicians who wish to incorporate psychedelics into their practices need training, and it will be essential to create evidence-based clinical-practice guidelines.

Despite the morbidity of SUDs and behavioral addictions, fewer than 10% of the 22 million Americans identified as needing treatment are able to access specialist services (6, 7). In the UK, only 9000 individuals were in contact with specialist gambling treatment clinics (6) in 2019–2020, despite a recent YouGov poll estimating that up to 1.4 million individuals living in the UK reach the threshold for problematic gambling (8). These figures lay bare the inadequate provision of support and access to treatment for addictions. 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). According to a 2018 review, between the 1950s and 1970s, researchers carried out early phase studies investigating the effectiveness of classic psychedelics, but then discontinued their work.

The study was halted part way through for cardiac safety concerns but the individuals who went through the study showed no sign of opiate withdrawal (30). To date, there has been no RCT evidence for Ibogaine, although efforts are now underway to restart this clinical development pipeline. No studies were identified evaluating the efficacy of psilocybin in patients with cocaine use disorder. A pilot double-blind, placebo-controlled RCT assessing the efficacy of psilocybin for cocaine use disorder and MRI assessment to determine a potential biological mechanism of psilocybin’s effect is ongoing. Emerging evidence suggests that certain psychedelics may have medicinal benefits for a range of health conditions, particularly common mental health conditions such as anxiety and depression.

Below we summarize the evidence from such studies in individuals with addiction using classic and non-classic psychedelics for therapeutic purposes and have summarized these findings in Table 1. FMRI studies have observed dysregulated neural responses to video and photo cues in individuals with addiction when compared with matched healthy control subjects. 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).

These individuals can experience ongoing mental health issues, such as paranoia, altered mood, and visual disturbances. Surgeons used PCP in the 1950s as a general anesthetic, but manufacturers stopped producing it due to its serious side effects, which included postoperative delirium and hallucinations. At high doses, PCP can cause seizures, severe muscle contractions, violent or aggressive behavior, and symptoms of psychosis.

Many rock stars helped fund Dr. Dave’s clinic, but some famous names include Jerry Garcia of the Grateful Dead, Janis Joplin, Jimi Hendrix, and George Harrison of the Beatles. Under the auspices of “Rock Medicine,” Dr. Dave and his volunteers began providing free medical care at rock concerts, talking down people with bad trips, helping concertgoers deal with adverse drug reactions and health problems, and assisting many thousands of patrons. The “Rock” doctors also helped rockers who overdosed or experienced drug abuse and dependence. Providing no-cost health care in a “Health Care Is a Right” setting was not the clinic’s only key underlying principle in 1967—or now.

“One of the things I fear is big companies will promote marijuana to youths as big tobacco did while denying they cause addiction with health consequences.” Smith wrote a personal account of his concerns in a scientific paper on psychedelics. He worries large corporations may similarly misuse psychedelics if researchers discover psychedelics are effective treatments for depression, anxiety, and other psychiatric disorders. In fact, in 2011, when the results of the first clinical trial to use psilocybin for over 35 years were published, it was a pilot study looking at the effect of psilocybin treatment in adults with advanced cancer and anxiety about death[6] . The study was carried out by a separate research group at New York University (NYU). Although the research primarily examined anxiety, Grob says there is “a lot of co-morbidity with anxiety and depression”. The group are now conducting a full-scale trial, but their ambitions do not stop there.

According to one clinical trial, these include derealization, which is when a person feels detached from their surroundings, and depersonalization, which is when they feel detached from their body or mind. Evidence is mounting that this approach could tackle addiction more generally. A recent study of the psychedelic drug ibogaine found it to be effective at treating addiction to alcohol, cannabis, cocaine and crack[3] . However, Johnson says ibogaine can have cardiovascular side effects and, in comparison, psilocybin is “very safe at a physiological level”. Robert West, a health psychologist at University College London who specialises in tobacco addiction, says that the study seems to have been well thought out and conducted, and there is a plausible rationale.

Stauffer said no comparative studies have yet compared the effects of ketamine-assisted therapy with psilocybin-assisted therapy, so researchers don’t yet have hard data about which might work better and why. Cognitive behavioral therapy “is a backdrop of therapy that we know can help people dealing with alcohol use disorder,” said Johnson of Johns Hopkins, who said therapy alone likely had a significant effect on people’s ability to curb their drinking, with or without psilocybin. Rigorous psychedelic drug trials are notoriously difficult to conduct, because participants know whether https://sober-home.org/ they are hallucinating. In addition, the new study is relatively small — only 93 participants — and researchers didn’t follow the participants after eight months, so it’s unclear how long the benefits lasted. During the eight-month trial, 93 men and women ages 25 to 65 were chosen to receive either two psilocybin doses or antihistamine pills, which the researchers used as a placebo. UAspire will follow participants for 54 weeks, randomizing some participants to 25 mg of psilocybin – a moderate-to-high dose – while others will receive a smaller 5 mg dose or an inactive placebo.

Where there are gaps in the current literature, we will offer examples of testable RSFC neuroimaging analyses that are able to probe the putative mechanisms of action of psychedelics in modulating addiction processes related to brain network dysfunction. The effect was sustained at 1 month and then a partial return to mild use followed at 2 months. Increases in brain https://sober-home.org/treatment-for-alcohol-problems-finding-and-getting-2/ perfusion were seen in the left putamen, and right insula, as well as temporal, occipital, and cerebellar regions, compared to the patient’s baseline scan. These regions have been implicated in the pathology of alcohol addiction, as assessed with functional and molecular neuroimaging, and are key hubs of the mesocorticolimbic dopaminergic reward system (55).

As for any new medical therapy, psychedelic research needs to be conducted in a rigorous manner, through the dispassionate lens of scientific enquiry. Carte blanche availability to practitioners, without specific protocols and appropriate training, would be potentially harmful to individuals and detrimental to the field. The smoking study results are promising, but Johnson says its relatively small size is a limitation. Also, subjects in such studies cannot comprise a completely random sample of the population, because it would be unethical to recruit people without telling them they may be taking a psychedelic drug. Thus, participants tend to be people who are open to this category of experience and, potentially, more apt to believe in its efficacy. And it is also hard to tease apart the effects of psilocybin from those of the cognitive-behavioral therapy in the smoking study, Johnson notes.
