In Maryland, operating a motor vehicle while under the influence of any substance that can impact the driver’s ability to drive safely is illegal. Alcohol is commonly thought of as such a substance, but in reality, any drug – illegal or prescription – qualifies as a substance that can land a driver with a DUI drugs charge. If an officer suspects a driver is under the influence of drugs, he/she may request chemical testing, but unlike alcohol, there is no legal limit for drugs, and there is no way to know what level would cause impairment. If testing shows a presence of drugs, whether or not to charge the driver with DUI drugs is ultimately left to the officer’s discretion.
