Thirteen male patients consecutively admitted to an inpatient drug and alcohol rehabilitation hospital with the primary diagnosis of crack cocaine dependence were shown a 30-minute videotape that included salient environmental cues intended to elicit cocaine craving. The subjects were tested before and after the videotape by the use of a continuous 20-cm analogue visual instrument that asks them to rate their perceived degree of craving, mood, energy, and wellness. Only craving showed a statistically significant change from pretest to posttest. Correlations among the four separate ratings suggest that mood and craving are different dimensions that independently contribute to one's general sense of well-being. This study demonstrates that cocaine craving can be induced in a group setting by presenting certain visual and auditory cues on a video monitor. The procedure of obtaining self-ratings in response to videotaped environmental cues could be easily incorporated into research methods designed to assess pharmacologic efficacy in reducing the intense craving that reinforces addiction.

Mindfulness Training vs Recovery Support for Opioid Use, Craving, and Anxiety During Buprenorphine Treatment: A Randomized Clinical Trial.
JAMA Netw Open

Department of Psychiatry, Harvard Medical School, Boston, Massachusetts.
Importance: During buprenorphine treatment for opioid use disorder (OUD), risk factors for opioid relapse or treatment dropout include comorbid substance use disorder, anxiety, or residual opioid craving. There is a need for a well-powered trial to evaluate virtually delivered groups, including both mindfulness and evidence-based approaches, to address these comorbidities during buprenorphine treatment.
Objective: To compare the effects of the Mindful Recovery Opioid Use Disorder Care Continuum (M-ROCC) vs active control among adults receiving buprenorphine for OUD.
Aim: Chronic cocaine use is associated with decreases in neuroactive steroid levels. These adaptations may contribute to continued cocaine use and high relapse risk in individuals with cocaine use disorder (CUD). Thus, this pilot study assessed chronic treatment with 2 supraphysiologic doses of the neuroactive steroid precursor pregnenolone (PREG, 300 mg/day; 500 mg/day) to boost endogenous neuroactive steroid levels and assess its impact on provoked craving and cocaine use outcomes in an 8-week trial in men and women with CUD.

The subject of substance use disorders in the pediatric population remains a disturbing conundrum for clinicians, researchers and society in general. Many of our youth are at risk of being damaged and even killed by drug addictions that result from the collision of rapidly developing as well as vulnerable central nervous systems encountering the current global drug addiction crisis. A major motif of this chemical calamity is opioid use disorder in adolescents and young adults that was stimulated by the 19th century identification of such highly addictive drugs as morphine, heroin and a non-opiate, cocaine.

Background: Opioid use disorder remains a critical healthcare challenge as current therapeutic strategies have limitations resulting in high recurrence and deaths. We evaluated safety and feasibility of focused ultrasound (FUS) neuromodulation to reduce substance cravings and use in severe opioid- and co-occurring substance use disorders.
Methods: This prospective, open-label, single-arm study enrolled 8 participants with severe, primary opioid use disorder with co-occurring substance use.
Cocaine-Induced Microglial Impairment and Its Rehabilitation by PLX-PAD Cell Therapy.

Chronic cocaine use triggers inflammatory and oxidative processes in the central nervous system, resulting in impaired microglia. Mesenchymal stem cells, known for their immunomodulatory properties, have shown promise in reducing inflammation and enhancing neuronal survival. The study employed the cocaine self-administration model, focusing on ionized calcium-binding adaptor protein 1 (Iba-1) and cell morphology as markers for microglial impairment and PLX-PAD cells as a treatment for attenuating cocaine craving.
