Your graph is so pretty. Opiates are now the leading cause of accidental deaths, surpassing car crashes and alcohol. http://elitedaily.com/news/world/prescription-painkillers-overtake-car-crashes-leading-accidental-death-us/
I went to the CDC site that was vaguely pointed to in the article you referenced and was unable to find the study sort of cited. Sad that there is no data more current than preliminary 2011 data. The existing CDC data does not back up your reference. Sorry.
