A sobering thought: One billion smokers and 240 million people with alcohol use disorder, worldwide

A new study has compiled the best, most up-to-date evidence on addictive disorders globally. It shows that almost 5 percent of the world's adult population (240 million people) have an alcohol use disorder and more than 20 percent (1 billion people) smoke tobacco. Getting good data on other drugs such as heroin and cannabis is much more difficult but for comparison the number of people injecting drugs is estimated at around 15 million worldwide.
