A new study from the Arizona State University Department of Psychology shows that the combination of genetic predisposition to alcohol use disorders and personality type can lead to problematic drinking behaviors. Having strong social support from friends was identified as protective against excessive drinking. The work was published in the Journal of Abnormal Psychology.
A new study from Arizona State University and Virginia Commonwealth University examined the pathways that contribute to and protect against alcohol use problems in Black American college students. Racial discrimination led to depressive symptoms and to problem alcohol consumption. Positive feelings about being a Black American were associated with a weaker link between discrimination, mental health and alcohol use. The study was published in Psychology of Addictive Behaviors.
Among adolescents ages 10 to 14 in the U.S, the overall rate of drug use remained relatively stable in the first six months of the COVID-19 pandemic. However, one change was a decreased use of alcohol, but an increased use of nicotine and misuse of prescription drugs.
During the COVID-19 pandemic months of March 2020 to September 2020, U.S. alcohol retail store sales increased compared to usual trends while food services and drinking places sales decreased markedly during the same period, according to a new study at Columbia University Mailman School of Public Health.

With overdose rates involving cocaine soaring nearly 27% in 2020, researchers at The University of Texas Health Science Center at Houston (UTHealth) hope that a clinical trial combining a medication approved for the treatment of Type 2 diabetes with cognitive behavioral therapy (CBT) can help prevent relapse in cocaine use disorder patients.
Emergency department visit rates because of an opioid overdose increased by 28.5% across the U.S. in 2020, compared to 2018 and 2019, recent Mayo Clinic research finds. Emergency visits overall decreased by 14% last year, while visits because of an opioid overdose increased by 10.5%. The result: Opioid overdoses were responsible for 0.32 out of 100 visits, or 1 in every 313 visits, which is up from 0.25, or 1 in every 400 visits, the previous two years.

Researchers successfully used a protein called parapinopsin to turn off brain circuits. This protein is found in lamprey – an ancient lineage of jawless fish similar to eel. Researchers said the ability to inhibit neurons could eventually lead to turning off mood disorders and unwanted behaviors like depression and addiction.
Frequent cannabis vaping, defined as vaping at least 10 times a month, more than doubled among high school seniors in the United States between 2018 and 2019, according to new research from NYU Grossman School of Medicine published online May 4 in the Journal of Adolescent Health.
Babies born to mothers diagnosed with cannabis use disorder are more likely to experience negative health outcomes, such as preterm birth and low birth weight, than babies born to mothers without a cannabis use disorder diagnosis, report UC San Diego researchers.
The drug buprenorphine is an effective treatment for opioid use disorder, but many who misuse opioids also take benzodiazepines — drugs that treat anxiety and similar conditions. Many treatment centers hesitate to treat patients addicted to opioids who also take benzodiazepines. Researchers at Washington University School of Medicine in St. Louis studied overdose risk in people taking buprenorphine and found that the drug lowered risk, even in people taking benzodiazepines.
IU study finds unintended and negative consequences of policies designed to reduce the supply of opioids in the population for overdose.
The National Institutes of Health (NIH) awarded Professor Mahesh Mohan, D.V.M., Ph.D., and collaborators more than $3.5 million over five years to investigate the effects of cannabinoids on Human Immunodeficiency Virus (HIV) associated neurocognitive disorder (HAND). This research project aims to evaluate whether delta-9-tetrahydrocannabinol (THC) and Cannabidiol (CBD) alone or in combination can potentially alter DNA methylation, which is a biological process that can create a change in the expression of certain genes.
More than a dozen drugs are known to treat symptoms such as hallucinations, erratic behaviors, disordered thinking and emotional extremes associated with schizophrenia, bipolar disorder and other severe mental illnesses. But, drug treatments specifically able to target the learning, memory and concentration problems that may accompany such disorders remain elusive.
This research helps illuminate the neural roots of emotions, and points to the possibility that a population of arousal-related neurons might be a target of future treatments for anxiety disorders and other illnesses involving abnormal arousal responses.
With support from a nearly $340,000 grant from the National Institute on Drug Abuse (NIDA) at the National Institutes of Health (NIH), Ian Mendez, Ph.D., UTEP assistant professor of pharmacy, is developing an animal model that mimics real life exposure to e-cigarettes in order to investigate the effects of nicotine vapor exposure on adolescent behavior.
Scientists at Wake Forest School of Medicine have recorded real time changes in dopamine and serotonin levels in the human brain that are involved with perception and decision-making. These same neurochemicals also are critical to movement disorders and psychiatric conditions, including substance abuse and depression.
Scientists at Sanford Burnham Prebys Medical Discovery Institute, Camino Pharma, LLC and University of California San Diego School of Medicine have been awarded an $11.4 million grant from the National Institute on Drug Abuse (NIDA) at the National Institutes of Health (NIH) to advance a novel drug candidate for nicotine addiction into first-in-human Phase 1 studies. The drug targets a neuronal signaling pathway underlying addictive behaviors, and would be a first-in-class medication to help people quit smoking.
Two UC San Diego School of Medicine-led analyses report that e-cigarettes are not effective in helping adults to quit smoking.
Middle-aged and older adults who identify as lesbian, gay, or bisexual have higher rates of using certain substances in the past year than those who identify as heterosexual, according to a new study led by researchers at NYU Grossman School of Medicine and the Center for Drug Use and HIV/HCV Research (CDUHR) at NYU School of Global Public Health.

Researchers in the Arizona State University Department of Psychology have shown that chemogenetic activation of the anterior insula restores prosocial behavior in an animal model of opioid addiction and empathy. The findings suggest an important role for the anterior insula in the brain response to addiction.
People who tend to recognize similarities between people they know and people depicted in the media are more likely to believe common myths about sexual assault, according to a new study co-led by a Cornell researcher.
More than $3.7 million was awarded to Mahesh Mohan, DVM, MS, Ph.D., Professor at the Texas Biomedical Research Institute, and Chioma M.
