Background: Chronic pain is highly prevalent among people in methadone maintenance treatment (MMT) for opioid use disorder and is known to be an important contributor to treatment discontinuation and opioid relapse. Mindfulness-Oriented Recovery Enhancement (MORE) is one of the few interventions developed and tested as an integrated treatment to simultaneously address both pain and illicit...
Background: Substance addiction is a psychosocial problem facing many people today. While the previous trend in addiction treatment was the harm reduction approach, nowadays it is fully recognized the importance of promoting human resources in order to help people to face the rehabilitation process, to prevent the risk of treatment dropout and future relapses, and to positively re-integrate...
Chronic drug use is theorized to induce cortico-striatal neuroplasticity, driving an allostatic process marked by increased sensitivity to drug-related cues and decreased sensitivity to natural rewards that results in anhedonia and a dearth of positive affect. As such, positive emotion regulation represents a key mechanistic target for addictions treatment. This paper provides a conceptual...

Introduction Classic psychedelics have been administered in sacramental contexts since ancient times. They were of prominent interest within psychiatry and neuroscience in the 1950s to 1960s, but the association between classic psychedelics and the emerging counterculture put an end to their research. Modern research with classic psychedelics has reinitiated interest in the treatment of both...
Despite extinction-based processes demonstrating efficacy in the animal extinction and human anxiety literatures, extinction for substance use disorders (SUD) has shown poor efficacy (i. e., cue exposure treatment [CET]). Reasons for this lack of success include common threats to extinction, such as renewal and reinstatement. In recent decades, research on mindfulness for SUD has flourished,...
The medical use of psychedelic substances (e.g. psilocybin, ayahuasca, lysergic acid diethylamide and 3,4-methylenedioxymethamphetamine) is attracting renewed interest, driven by a pressing need for research and development of novel therapies for psychiatric disorders, as well as promising results of contemporary studies. In this Viewpoint, we reflect upon the ‘Clinical Memorandum on...
Internet addiction is a growingly prevalent behavioral addiction that causes numerous psychosocial problems. Investigating the causes and consequences of Internet addiction is fundamental to comprehend and prevent it. Therefore, the current study provided protective and promotive factors for undesired effects of social exclusion on Internet addiction. The study examined a moderated mediation...
Background A version of ketamine, called Esketamine has been approved for treatment-resistant depression (TRD). Ketamine (“K powder”), a “dissociative” anesthetic agent, however, has been used non-medically alone or with other illicit substances. Our previous studies showed a link between non-medical ketamine use and brain structural and functional alterations. We found dorsal prefrontal gray...
Background: 3,4-methylenedioxymethamphetamine (MDMA) therapy has qualities that make it potentially well suited for patients with addictions, but this has never been explored in a research study. We present data from the Bristol Imperial MDMA in Alcoholism (BIMA) study. This is the first MDMA addiction study, an open-label safety and tolerability proof-of-concept study investigating the...
It is tough to write about psychedelics without a few gratuitous puns. Regardless, Michael Pollan’s “How to Change Your Mind” is definitely “mind expanding” and deserves my “highest” recommendation. Published in 2019, this book comprehensively and presciently covers a topic of increasing interest: whether psychedelic agents can revolutionize mental health. Pollan is not a Medical Doctor but is...
