According to the 2014 National Survey on Drug Use and Health (NSDUH), 10 million people aged 12 or older reported driving under the influence of illicit drugs. As more states have legalized medical and recreational marijuana and with the high prevalence of prescription drug use in the United States, drugged driving has become a public health issue. In response, states have passed laws intended to decrease traffic accidents and deaths related to drugged driving. All states have laws prohibiting driving under the influence; however, the Office of National Drug Control Policy encourages states to pass zero tolerance per se drug impairment laws, a policy which prohibits driving with any or only a specific amount of a controlled substance in a person’s body. The following dataset shows specific variables of each state’s drugged driving law.
