Teen binge drinking disrupts brain development, affecting white and grey matter, functional connectivity, and neurodevelopmental processes like myelination.

Researchers found that methamphetamine and PCP cause a phenomenon known as neurotransmitter switching, impairing memory. This change is reversible, pointing to potential treatments for drug-induced cognitive deficits and related neuropsychiatric conditions.

Researchers found that people with alcohol use disorder have unique brain connectivity patterns, especially in areas tied to self-control and decision-making, which may explain impulsive drinking behaviors and offer clues for improving diagnosis and treatment.

Adolescents with lower sustained attention and specific brain activity patterns at age 14 were more likely to increase cigarette and cannabis use by age 23, suggesting early attention ability predicts future substance use risk.

Children of parents with substance use disorders face a significantly higher risk of psychiatric diagnoses, with males at 80% and females at 56% increased risk.

Highly religious individuals are more likely to view their pornography use as compulsive, influenced by moral disapproval rather than actual behavioral issues, especially among frequent worship attendees.

Emotional distress and inflammation are more prominent in alcohol use disorder patients with a history of childhood stress, such as abuse or neglect, according to new research.

A study has found that moral incongruence and frequency of pornography use jointly mediate the relationship between sexual satisfaction and psychological distress from pornography use.

Researchers discovered that dopamine pathways from the ventral tegmental area to the amygdala play a crucial role in forming cocaine-cue associations, driving cocaine-seeking behavior, and increasing relapse risk, suggesting potential targets for addiction treatment.

A new study suggests that asking women to recall a recent drinking experience, particularly with a focus on calorie consumption, can reduce their desire to drink alcoholic beverages.

Childhood adversity may have a lasting impact beyond early years, potentially influencing how young adults engage with short-form video platforms like TikTok, a new study suggests.

People with antisocial personality disorder are more prone to severe alcohol, cannabis, and tobacco misuse, particularly hazardous use, highlighting the need for tailored treatment strategies for this high-risk population.

A new study reveals increased pornography use among Swedish adolescents and a narrowing gender gap in responses. Both boys and girls have become more tolerant of pornography but increasingly critical of its societal benefits.

A study of dark personality traits has found narcissism and everyday sadism to be the strongest predictors of higher sex drive and pornography use, indicating a stronger link between these traits and sexual motivation than previously thought.
