Answer: Wisconsin law doesn’t define an intoxicant itself. A lot of law enforcement officers will talk about an odor of an intoxicant and that means alcohol to them. So they’re definitely referencing alcohol. Under Wisconsin OWI law, you can be convicted of operating while impaired for alcohol, for controlled substances, for prescription medication if it is either over the dose or if you do not have a prescription for the medication, they can try and prove impairment based on any of those. But the general, when people talk about an intoxicant—specifically when law enforcement talks about an intoxicant—they’re usually referencing alcohol.
