When people think of a DUI charge (called ‘OVI’ in Ohio), most think of drunk driving. This is where the bulk of the money and effort have been concentrated to raise awareness: think of the “Buzzed Driving is Drunk Driving” or “Over the Limit, Under Arrest” advertising campaigns. However, with more states legalizing marijuana for medical and recreational use, more people are finding themselves charged with OVI stemming from alleged marijuana impairment. This is a trend we have been following for some time. For people charged with a Marijuana OVI, a frequent question is: How long is THC detectable in your system?
