Dosages matter. The risk of death from an overdose with patients prescribed at least 100 mg daily morphine equivalent is about 7 times higher than a patient prescribed less than 20 mg of morphine a day.

All pain is real. It’s just a question of whether that pain is being triggered by a physical injury or by something else. Studies show that emotional injury activates the same areas of the brain as does physical injury.

New evidence suggests that the prevalence of fetal alcohol spectrum disorder is higher than previously documented. In this study, prevalence estimates were derived from 13,146 first-grade children in four U.S. communities between 2010 and 2016.

Acting on the nicotinic acetylcholine receptors, varenicline (Chantix) is an FDA-approved treatment for smoking cessation. These receptors are implicated in both nicotine and alcohol reward pathways, so could varenicline also be helpful for treating alcohol use disorder (AUD)?

Recent guidelines published by the American Society of Addiction Medicine and nationally in Australia provide support for transferring patients from methadone to buprenorphine-naloxone (BNX). Patients may switch, thinking BNX is easier to discontinue or because of methadone side effects.

Over the last few decades, doctors have done a better job at convincing their patients to stop smoking. But much of this improvement has been relegated to patients without mental illness.

A large focus of my career has been on doing National Institutes of Health–sponsored research into better understanding substance use disorders in young people. So, that would include adolescents and young adults.

You’ve probably read about internet gaming disorder (IGD), and even heard about a man in Taiwan who died while continuously playing online games for 3 straight days. There’s still debate over how to classify and treat pathological gaming: Is it its own disorder, or just a symptom of another underlying mental illness?

Considering them less lethal than traditional cigarettes, many adolescents are turning to electronic cigarettes as a “safer” alternative to tobacco products.
