A study published in JAMA Network Open found that over 60% of US adults who vape are interested in quitting, with former cigarette smokers having the highest intentions. Despite e-cigarettes being seen as a potential tool for smoking cessation, many users struggle to quit, and current treatments may not be effective for all users.
A team of neurobiologists identified a brain region, subthalamic nucleus, that predicts addiction in rats. Abnormal activity in this region was observed in future addicted individuals before punishment exposure.

Patients taking buprenorphine for opioid use disorder who also take benzodiazepines experience a 40% lower risk of overdose, according to research published in The American Journal of Psychiatry. This finding suggests that buprenorphine can protect patients from overdose even when taking benzodiazepines.
The opioid overdose epidemic in the US is fueled by restricted access to evidence-based treatments, with only 18% of individuals receiving effective medications. Proposed exemptions aim to expand access, but more changes are needed to address the crisis.

Researchers found that sugar intake alters the brain's dopamine and opioid systems, activating the reward system after just 12 days. This suggests that sugar can be an addictive substance, pushing natural stimuli like social interaction or learning into the background.
A set of four integrated studies by Harvard researchers reveals that sadness plays a strong role in triggering addictive behavior relative to other negative emotions like disgust. The studies show that individuals experiencing sadness are more likely to be smokers and relapse into smoking after quitting.
A study by researchers at UC San Francisco found that fewer than half of California pharmacies provided correct disposal instructions for antibiotics and opioids. Only 10% followed the FDA's recommended takeback programs. Improving disposal practices requires better education and expanded programs to ensure patient safety.
Researchers at Stanford University School of Medicine have identified a specific brain chemical, serotonin, responsible for the social behavior-enhancing effects of MDMA. The study suggests that novel treatments targeting this pathway may alleviate symptoms of psychiatric disorders marked by social awkwardness and withdrawal.
