Substance.com pulled data from the Substance Abuse and Mental Health Services
Administration, the FBI, and the Centers for Disease Control to create a
real-time snapshot of US drug use, plus a few other mental health and social issues.
Each number below represents the "real-time" usage and incident rate.*
Every time the number changes, a new person has engaged in the named behavior (according to averages of the available data as of September 2014).
