Yes. Driving under the influence of marijuana is a DUI offense in Rhode Island, even though recreational marijuana possession for adults 21 and over was legalized in 2022. The legal threshold for marijuana DUI is impairment, not a specific THC blood level, because Rhode Island has no statutory per se THC limit. Police can charge marijuana DUI based on driving behavior, field sobriety performance, officer observations of impairment signs (red eyes, odor, slowed responses), and any chemical test results. Convictions carry the same DUI penalties as alcohol DUI: fines, license suspension, possible jail, and a permanent record.
