Every state has laws dealing with alcohol-impaired driving and drug-impaired driving. But unlike the laws for drunk driving, those that address drugged driving are nuanced, difficult to enforce and prosecute and vary substantially by state.
In addition to general impairment laws, there are two basic laws that states tend to use when addressing drug-impaired driving:
18 states have zero tolerance or non-zero per se laws for marijuana.
NOTE: GHSA does not compile any additional data on drug-impaired driving laws other than what is presented here. A compilation of state marijuana laws is available via the Insurance Institute for Highway Safety, and information on marijuana-impaired driving laws is available from the National Alliance to Stop Impaired Driving (NASID). For more information, consult the appropriate State Highway Safety Office.
