INTRODUCTION: Combinations of psychotherapy with antidepressants are gold-standard psychiatric treatments. They operate through complex and interactional mechanisms, not unlike the reemergent paradigm of psychedelic-assisted psychotherapy, which promising research suggests may also be highly effective in even challenging populations. AREAS COVERED: We review the therapeutic mechanisms behind...

Ayahuaska, zwana również „lianą duszy”, „pnączem duszy” to rytualny psychodelik podawany tradycyjnie w formie wywaru roślinnego, od stuleci stosowany przez rdzenną ludność Ameryki Południowej, a w ostatnich 25 latach również w krajach Europy, Azji, Afryki, Australii, w Kanadzie i Stanach Zjednoczonych Ameryki Północnej. Jej aktywność biologiczna wynika z zawartości N,N- dimetrylotryptaminy...
Abstract Psychoactive substances with chemical structures or pharmacological profiles that are similar to traditional drugs of abuse continue to emerge on the recreational drug market. Internet vendors may at least temporarily sell these so-called designer drugs without adhering to legal statutes or facing legal consequences. Overall, the mechanism of action and adverse effects of designer...
Though the field is young, psychedelics appear to hold promise as a treatment for addiction, even as barriers to research persist. Researchers around the world are investigating how drugs such as LSD, MDMA (also known as ecstasy), ketamine, and psilocybin (the active ingredient in magic mushrooms) can treat patients with substance use disorders (SUD). Though there is still a lot to learn, early...
Abstract There are few medications with demonstrated efficacy for the treatment of posttraumatic stress disorder (PTSD). Treatment guidelines have unequivocally designated psychotherapy as a first line treatment for PTSD. Yet, even after psychotherapy, PTSD often remains a chronic illness, with high rates of psychiatric and medical comorbidity. Meanwhile, the search for and development of drugs...
AIMS To explore the feasibility of delivering community-based drug safety testing ('drug checking'), to trial service design characteristics and to compare with festival-based testing. METHODS 171 substances of concern were submitted on five dates at three venues in two UK cities and tested using up to six analytical techniques. Test results and harm reduction advice were distributed directly...
Ketamine, N,N-dimethyltryptamine (DMT), and other psychoplastogens possess enormous potential as neurotherapeutics due to their ability to potently promote neuronal growth. Here, we report the first-ever structure-activity relationship study with the explicit goal of identifying novel psychoplastogens. We have discovered several key features of the psychoplastogenic pharmacophore and used this...
Treatment-resistant depression (TRD) is a subset of Major Depressive Disorder which does not respond to traditional and first-line therapeutic options. There are several definitions and staging models of TRD and a consensus for each has not yet been established. However, in common for each model is the inadequate response to at least 2 trials of antidepressant pharmacotherapy. In this review, a...
Neuroimaging studies of the psychedelic state offer a unique window onto the neural basis of conscious perception and selfhood. Despite well understood pharmacological mechanisms of action, the large-scale changes in neural dynamics induced by psychedelic compounds remain poorly understood. Using source-localised, steady-state MEG recordings, we describe changes in functional connectivity...
The pathophysiology and treatment of depression have been the focus of intense research and while there is much that remains unknown, modern neurobiological approaches are making progress. This work demonstrates that stress and depression are associated with atrophy of neurons and reduced synaptic connectivity in brain regions such as the hippocampus and prefrontal cortex that contribute to...
