Ohio and Pennsylvania are two states which still prosecute drivers for DUI / OVI marijuana, even if the marijuana metabolites in the driver’s system are not affecting the person’s ability to drive. The Philadelphia District Attorney’s office recently announced it will not prosecute cannabis DUIs unless the driver has amounts of psychoactive THC which affect driving. Ohio prosecutors should consider implementing this policy.
Two Types Of DUI/OVI Laws In Ohio
Ohio’s two general types of OVI are OVI ‘impaired’ and OVI ‘per se’. For a charge of OVI ‘impaired’, the prosecution must prove that, at the time of operating the vehicle, the driver was ‘under the influence’ of alcohol and/or drugs. ‘Under the influence’ means the alcohol and/or drugs “affected the nervous system, brain or muscles of the defendant so as to impair, to a noticeable degree, his ability to operate the vehicle”.
For a charge of OVI ‘per se’ the prosecution must prove that, at the time of operating the vehicle, the driver had a prohibited concentration of alcohol or drugs in his breath, blood or urine. The prohibited concentration of alcohol is .08%. The prohibited concentration of marijuana metabolite is 35 nanograms per milliliter of urine or 50 nanograms per milliliter of blood.
