Discover the complexities of substance abuse beyond dopamine and impulsivity. A groundbreaking study challenges the conventional belief that regular cocaine use reduces the brain’s ability to produce dopamine. Impulsivity, rather than risky decision-making, predicts increased cocaine use, and individual differences in drug abuse vulnerability may stem from variations in how dopamine release is controlled. This research sheds new light on why some individuals are more vulnerable to substance abuse than others and explores the interplay between personality traits and brain chemistry.
