Is it legal to drive a motor vehicle under the influence of marijuana in Oregon?

Driving a motor vehicle under the influence of marijuana is illegal in Oregon, just as it is for alcohol and other controlled substances. This prohibition is in place to ensure road safety and to reduce the risk of accidents caused by impaired driving. The law does not allow any level of impairment, and drivers can be prosecuted for driving under the influence regardless of whether they are under the legal limit for THC or not.

While certain conditions might exist for medical marijuana users or those over 21 regarding possession or consumption, these do not extend to the legality of driving under the influence. Therefore, the assertion that it is illegal to drive while impaired by marijuana aligns with the state's strict laws aimed at minimizing the dangers associated with impaired driving.
