Heavy alcohol consumption (3 drinks or more/day for women and 4 drinks or more/day for men) is linked to alterations in immune function among people with HIV.
A research study into New Psychoactive Substances (NPS) -- formerly referred to as 'legal highs' -- provides new evidence about why young people were attracted to the drugs, and the health and social risks associated with taking them. The study was carried out by an interdisciplinary team of researchers from Queen's University Belfast. The research findings recommend support using existing evidence-based interventions among young people and high risk populations.
The prevalence of depression, cannabis use, and alcohol abuse increased among former smokers from 2005 to 2016 in the U.S., according to a new study by researchers at Columbia Mailman School of Public Health. Therefore, increases in these risk factors for relapse among former smokers could threaten progress in reducing the prevalence of cigarette use. This is the first national US study to focus on the prevalence and time trends of depression, marijuana use, and problematic alcohol use among former smokers.
Spending on cannabis, cocaine, heroin and methamphetamine fluctuated between $120 billion and $145 billion each year from 2006 to 2016, rivaling what Americans spend each year on alcohol, according to a new study.
There is a dearth of scientifically investigated, evidence-based interventions to address substance use, mental health problems and violence victimization in sexual and gender minority youth, according to a research review. After poring over thousands of research publications spanning nearly two decades, the scientists identified only nine studies that evaluated such interventions and most of these used suboptimal study designs, thereby limiting the validity of the findings. None of the programs would be sufficient to mitigate the substantial population-level inequities faced by LGBTQ youth.
Parents and teens find it difficult to talk about sex and alcohol, and this study finds that doctors can help. This randomized clinical trial evaluated whether interventions targeted at parents in primary care pediatric settings might improve communications between parents and their teens about sexual health and alcohol use.
Patients who meet an addiction medicine consult team while they're in the hospital are twice as likely to participate in treatment for substance use disorder after they go home, according to new research. The study measures a key outcome for patients who participated in a first-of-its-kind addiction intervention program started by Oregon Health & Science University in 2015.
Mothers who drink moderate to high levels of alcohol during pregnancy may be changing their babies' DNA, according to a Rutgers-led study.
Compared to people who only drank alcohol, those who used alcohol and marijuana simultaneously were more likely to drink heavier and more often, according to researchers. They were also more likely to experience alcohol-related problems -- like impulsive actions they later regretted.
Not a good mix: A researcher from the University of Houston has found that adults who combine prescription opioids for severe pain and cannabis report elevated anxiety and depression symptoms, with no increased pain reduction.
