Addiction

While physical activity generally protects against addiction, a new study indicates it may intensify problematic pornography use when the behavior is driven specifically by a desire to alleviate stress.

New research suggests that alcohol use disorder triggers a specific immune response. This activation prompts astrocytes to damage neurons, providing a pathway for alcohol-related neurodegeneration.

A new study highlights distinct psychological profiles for gamblers. While strategic players show higher rates of narcissism-fueled addiction, mixed gamblers are driven by the belief that they are personally lucky.

Researchers have found that while negative thought patterns and emotional struggles both predict problematic pornography use, one does not cause the other. The path from psychological distress to addiction is more complex than expected.

A large study published in JAMA Psychiatry finds that lower IQ scores at age 18 are linked to increased risk of alcohol use disorder. Genetic factors and societal conditions both appear to influence how this risk develops over time.

A new study suggests that semaglutide, a drug best known as Ozempic, may reduce cocaine use, motivation, and relapse in rats. These findings point to a possible role for GLP-1-based drugs in treating cocaine addiction.

Problematic pornography use and repetitive negative thinking appear to reinforce each other, according to new research in The Journal of Sex Research. The study tracked young adults over a year and found distinct patterns in how men and women are...

How does the brain learn to link alcohol with relief from withdrawal, creating a powerful cycle of relapse? A new study isolates a specific cluster of neurons that becomes highly active, essentially locking in this compulsive behavior.

New research finds a powerful tool against the opioid crisis inside jail walls. Providing addiction medication to incarcerated individuals is associated with a 52% lower risk of fatal overdose and a 12% lower risk of returning to jail.
