In contrast, researchers say use of illicit drugs was far less common.
Washington: Alcohol and tobacco use has cost humans more than a quarter of a billion disability-adjusted life years, suggests a recent study.
The research compiles the best, most up-to-date source of information on alcohol, tobacco, and illicit drug use and the burden of death and disease in 2015.
The largest health burden from substance use was attributed to tobacco smoking and the smallest was attributable to illicit drugs. Global estimates suggest that nearly one in seven adults (15.2 percent) smoke tobacco and one in five adults report at least one occasion of heavy alcohol use in the past month.
Compared with the rest of the world, Central, Eastern, and Western Europe recorded consistently higher alcohol consumption per capita (11.61, 11.98 and 11.09 litres, respectively) and a higher percentage of heavy consumption amongst drinkers (50.5, 48.2, and 40.2 percent, respectively).
The same European regions also recorded the highest prevalence of tobacco smoking (Eastern Europe 24.2 percent, Central Europe 23.7 percent, and Western Europe 20.9 percent).
In contrast, use of illicit drugs was far less common. Fewer than one in twenty people were estimated to use cannabis in the past year, and much lower estimates were observed for amphetamines, opioids and cocaine.
Some countries and regions (Africa, Caribbean and Latin America, Asia regions) have little or no data on substance use and associated health burden.
These are typically low or middle-income countries that frequently have punitive drug policies, and may experience serious political and social unrest. These countries need enhanced monitoring because they are at risk of rapid escalation in substance use and related health burden.
The research used data mainly obtained from the World Health Organisation (WHO), United Nations Office on Drugs and Crime, and Institute for Health Metrics and Evaluation.
The study is published in the journal Addiction.
