Alcohol, Drugs, DUI — United States

Alcohol and drug United States expert witnesses provide opinions on criminal allegations of being under the influence of alcohol, prescription medicines, recreational drugs, narcotics, or other intoxicating substances, including driving while intoxicated (DWI / DUI). The toxicology experts in drug and alcohol listed here may consult on issues involving the influence and adverse effects of drugs and alcohol, including drug interactions, overdose, alcohol related injury or death. The toxicology scientists and law enforcement experts in criminal drug and alcohol use listed here may testify on issues of police standards in identifying intoxicated drivers, racial profiling, driving distractions, confusing instructions in field sobriety tests, and the misidentification of intoxication for other physical and mental states, including the effects of sleep medication and lack of sleep, allergies and contact lenses, and causes of slurred speech other than intoxication. These DUI/DWI experts may also opine on issues of intoxication levels while driving under the influence of drugs and alcohol, as well as intoxication levels in those driving or working in safety sensitive occupations, such as operators of heavy machinery, airline pilots, police and other first responders. Some experts listed here may provide written opinions on diversion to alcohol and drug treatment facilities in alternative sentencing programs.
