A global review of data from 2015 shows that significantly more people died from alcohol and tobacco use than did from the use of illicit drugs. The study published in the Journal Addiction shows that out of every 100,000 deaths, more than 110 were caused by tobacco, 33 by alcohol and fewer than seven by the use of illicit drugs.
The largest health burden from substance use was attributed to tobacco smoking and the smallest to illicit drugs. Globally, it’s estimated that almost one in seven adults smoke tobacco and one in five adults report at least one bout of heavy alcohol consumption in the past month.
Canada had high rates of illicit drug use
Higher alcohol consumption was recorded in Central, Eastern and Western Europe. These same regions also had the highest prevalence of tobacco smoking.
Canada and the U.S. had among the highest rates of cannabis, opioid and cocaine dependence. Australia and New Zealand had the highest prevalence of amphetamine dependence.
Risk of escalating substance use in some regions
Some countries and regions, such as those in Africa, the Caribbean and Latin America, and Asia have little or no data on substance use. The researchers suggest “these countries need enhanced monitoring because they are at risk of rapid escalation in substance use and related health burden.”
The data were drawn mainly from the World Health Organization, United Nations Office on Drugs and Crime and Institute for Health Metrics and Evaluation. The authors note there are important limitations to the data but believe they “will make it easier for governments and international agencies to develop policies to combat substance use.”
