Driving under the influence; making certain exception for marijuana, marijuana derivatives, and synthetic cannabinoids; effective date.

HB 3018 amends Oklahoma's driving under the influence (DUI) law to exclude marijuana, marijuana derivatives, and synthetic cannabinoids from the rule that prohibits driving with any detectable amount of a controlled substance in one's system. Previously, having any amount of a Schedule I controlled substance (like certain drugs) could lead to a DUI charge, but this bill removes that requirement specifically for the listed marijuana-related substances. This means a driver cannot be charged under this section solely for having any amount of these substances present. However, drivers can still face DUI charges if they are impaired by these substances or if they have other controlled substances in their system.
