Drinking and driving have been a serious problem in the United States for many years. The words DUI (driving under the influence) and DWI (driving while intoxicated) are all too familiar to most of us. Drunk driving has been responsible for the loss of thousands of lives in this country.
It may surprise you to find out that these terms DUI, DWI can also be used in regard to driving under the influence of either prescription or illegal drugs. The fact is, they can and do also refer to a driver who is under the influence of (impaired) either illegal or prescription drugs, as well as alcohol.
A person who uses psychoactive drugs and then proceeds to drive a vehicle is an issue of ongoing concern to authorities. It is an issue of continual concern to law enforcement officers, forensic toxicologists, attorneys, physicians and traffic safety professionals in every state in the United States. Some of the things that are matters of concern are ways to identify the drug impaired driver on the road, the availability of appropriate chemical tests, the documentation and assessment of the impairment displayed by the driver and the interpretation of the subsequent results.
