There were 80,000 drug and alcohol-related overdose deaths in the U.S., according to the Centers for Disease Control and Prevention’s WONDER database in 2010 — the most recent year statistics are available.
The rate of reported overdoses [in] the U.S. more than doubled between 1999 and 2010. About half of those additional deaths are in the pharmaceuticals category, which the CDC has written about before. Nearly three-quarters of the pharmaceuticals deaths are opioid analgesics—prescription painkillers like OxyContin and Vicodin. And while cocaine, heroin and alcohol are all responsible for enough deaths to warrant their own stripes on the chart, many popular illegal drugs—including marijuana and LSD—are such a tiny blip as to be invisible.
