Tobacco use is the leading cause of preventable death and disability in the U.S., while heavy drinking ranks as the third leading cause of preventable death. Cigarette taxation has been recognized as one of the most significant policy instruments to reduce smoking. Given that smoking and drinking often occur together, a first-of-its-kind study has examined cigarette taxation and found that increases are associated with modest to moderate reductions in alcohol consumption among vulnerable groups.
Results will be published in the January 2014 issue of Alcoholism: Clinical & Experimental Research and are currently available at Early View.
"Smoking and heavy drinking co-occur at alarmingly high rates," said Sherry McKee, associate professor of psychiatry
at Yale University School of Medicine as well as corresponding author for the study. "Tobacco can enhance the subjective effects of alcohol and has been shown to increase the risk for heavy and problematic drinking. Smokers drink more frequently and more heavily than non-smokers, and are substantially more likely than non-smokers to meet criteria for alcohol abuse or dependence. The co-occurrence of smoking and drinking is of particular clinical significance given evidence that health consequences exponentially increase with combined versus singular abuse of alcohol and tobacco."
"Smoking and drinking are strongly linked for a host of reasons including complementary pharmacologic effects, shared neuronal pathways, shared genetic associations, common environmental factors, and learned associations," added Christopher W. Kahler, professor and chair of the department of behavioral and social sciences at Brown School of Public Health. "However, it is possible to intervene through behavioral treatments, pharmacotherapy, and policy to affect both behaviors in a positive way."
"Cigarette taxes have broad population reach and have been recognized as one of the most significant policy instruments to reduce smoking," said McKee. "Increases in cigarette taxes predict decreases in smoking initiation, increases in quitting, and reductions in cigarette-related morbidity and mortality. By increasing the price of cigarettes, taxes are thought to encourage smokers to reduce their use of cigarettes or quit altogether, and discourage non-smokers from starting to smoke."
McKee and her colleagues examined data gathered through personal interviews with 21,473 alcohol consumers as part the National Epidemiological Survey on Alcohol and Related Conditions, a survey conducted by the National Institute on Alcohol Abuse and Alcoholism. Analyses evaluated whether increases in cigarette taxes between Waves I (2001-2002) and II (2004-2005) were associated with reductions in quantity and frequency of alcohol consumption. These analyses were conducted by gender, hazardous drinking status, age, and income group, and were further adjusted for demographics, baseline alcohol consumption, and alcohol price.
