Driver A has had no alcohol, but she took a prescription pain medicine that makes her drowsy and slow to react. Could she be charged with DWI in Missouri?
Correct answer: Yes, because impairment by any drug, even a legal one, is DWI
Why
Under Missouri law, a person is in an intoxicated condition when under the influence of alcohol, a controlled substance, a drug, or any combination of these. Mixing a medicine or marijuana with alcohol makes the impairment worse. Medical marijuana is no exception: it is never legal to drive while under its influence.
