9 open-access addiction studies, each with a flashcard deck and a quiz.
- Do GLP-1 drugs lower AUD hospitalizations?
In 227,866 Swedes with AUD, semaglutide (aHR 0.64) and liraglutide (aHR 0.72) use periods had lower AUD hospitalization risk than nonuse—stronger than approved AUD meds overall.
- Does binge drinking change how the brain resists emotional distraction?
College freshmen who binge drank more often showed weaker activation in frontal control regions when they had to hold back a response while upsetting images were in the background, even though their task performance looked normal.
- Do heavy social-media users have weaker brakes on their actions?
Students who used social networking apps excessively responded as accurately as other students on a stop-or-go task, but their brain responses suggested weaker response inhibition and extra attention to social-media logos.
- How does meth dependence change learning and choices?
People with methamphetamine dependence rely on simpler, short-term decision strategies and show lower expectations of non-drug rewards compared to healthy individuals.
- Does trouble managing emotions link discrimination to substance use?
LGB adults who reported more family rejection or victimisation had more difficulty regulating emotions, and that difficulty statistically accounted for part of their higher alcohol and drug problems.
- Does the gambler's brain respond differently while awaiting a reward?
Abstinent problem gamblers showed weaker insula activity while anticipating a reward, and this weakening was greater the longer they had been ill.
- Do gambling and cocaine addiction impair learning from feedback differently?
Heavier gamblers were slower to adapt when the rewarded option switched and showed abnormal brain responses to feedback, whereas cocaine users' problems were tied to their lifetime amount of use and showed up as poorer steady-state choices.
- Can a single session of cycling reduce heroin cravings?
A single session of high-intensity cycling reduces self-reported cravings and improves brain indicators of self-control in men recovering from heroin addiction.
- Are problem internet users impulsive in the same way as smokers?
