Disability-adjusted life year for drug use disorders per 100,000 inhabitants in 2004. The initiation of drug use including alcohol is most likely to occur during adolescence, and some experimentation with<unk> s by older adolescents is common. For example, results from 2010 Monitoring the Future survey, a nationwide study on rates of<unk>  use in the United States, show that 48.2% of 12th graders report having used an illicit drug at some point in their lives. In the 30 days prior to the survey, 41.2% of 12th graders had consumed alcohol and 19.2% of 12th graders had smoked tobacco cigarettes. In 2009 in the United States about 21% of high school students have taken prescription drugs without a prescription. And earlier in 2002, the World Health Organization estimated that around 140 million people were alcohol dependent and another 400 million with alcohol-related problems. Studies have shown that the large majority of adolescents will phase out of drug use before it becomes problematic. Thus, although rates of overall use are high, the percentage of adolescents who meet criteria for<unk>  is significantly lower (close to 5%). According to BBC, "Worldwide, the UN estimates there are more than 50 million regular users of morphine diacetate (heroin), cocaine and synthetic drugs." More than 70,200 Americans died from drug overdoses in 2017. Among these, the sharpest increase occurred among deaths related to fentanyl and synthetic opioids (28,466 deaths). See charts below.
