Addictive Screen Use, Not Time, Tied to Teen Suicide Risk

A major new study reveals that teens who develop compulsive patterns of digital use are at higher risk of suicidal thoughts, attempts, and mental health issues. Unlike total screen time, it’s the addictive nature of use—such as distress when not online or using screens to escape—that most strongly predicts poor outcomes.

Ibudilast Fails to Beat Placebo in Alcoholism Trial, Except in Women

A recent clinical trial found that ibudilast, a drug once promising for alcohol use disorder, was no more effective than a placebo overall. While all participants reduced their drinking, women on ibudilast showed a greater drop in drinks per day, hinting at a gender-specific benefit.

How Cocaine Hijacks the Brain

In a groundbreaking study, researchers have engineered fruit flies that voluntarily consume cocaine, creating the first fly model for cocaine addiction. Typically, flies avoid the drug due to its bitter taste, but by disabling their bitter-sensing receptors, scientists encouraged addictive behavior within just 16 hours of exposure.

Public Favors Some Organ Recipients Over Others

Americans tend to judge organ transplant eligibility based on the cause of a person’s illness rather than their race or ethnicity. Survey participants consistently favored recipients whose conditions were seen as less self-inflicted—such as black lung disease from coal mining or genetic kidney failure—over those with alcohol use disorder or unvaccinated COVID-19 complications.

Social Status Shapes Addiction Risk Through Dopamine Circuitry

A new study reveals how social rank influences addiction vulnerability by altering dopamine pathways in the brain. Low-ranking male mice showed stronger reward signals and weaker control circuits, making them more prone to seek methamphetamine, while high-ranking mice had better balance and resistance.

Addiction Accelerates Brain Aging via Distinct Molecular Pathways

Substance use disorders (SUDs) accelerate biological aging in the brain through substance-specific molecular mechanisms. Using brain-specific epigenetic clocks, researchers found that alcohol, opioids, and stimulants each trigger unique patterns of neurodegeneration, particularly in the decision-making centers of the brain.

Tiny Brain Structure Reveals New Paths to Treat Addiction, Depression

New research spotlights the habenula, a tiny but powerful brain region, as a key player in addiction, motivation, and emotional regulation. Studies show that the habenula’s circuitry influences how the brain processes rewards, disappointment, and drug cravings, offering potential drug targets like the GPR151 receptor.

Early Substance Use Linked to Brain Structure Differences in Teens

A study of nearly 10,000 adolescents found that those who initiated substance use before age 15 exhibited distinct differences in brain structures compared to their peers. Many of these differences were present before substance use, suggesting a role in predisposing factors like genetics and environment.

Aversion Shapes Addiction Risk in Early Drug Use

New research reveals that initial reactions to unpleasant drug experiences, like bitterness or discomfort, may predict susceptibility to addiction. In a rat study, individual responses to a bitter-tasting cue paired with cocaine varied widely, with some avoiding the drug entirely and others increasing consumption over time.
