People who’ve been provoked to anger are willing to purchase alcohol at higher prices, but may not be aware of their increased urge to drink, according to a new study. Anger, hostility, and aggression are known to relate to drinking, with anger a risk factor for heavy alcohol use. Building on previous studies that have deliberately manipulated emotional states to explore their effects on substance use, researchers at Wayne State University, Michigan, designed an experiment that could help clarify whether anger can motivate people to drink . For the study in Alcoholism: Clinical and Experimental Research, the investigators sought to induce anger in participants and measure the effect of that anger on the desire to drink. They used two measures of drinking urges: self-reported alcohol craving and a behavioral task that assesses people’s motivation to drink.
