When a driver is charged with DUI, it is not always for being under the influence of alcohol. Alcohol and DUI are often perceived as going hand in hand. This is a common assumption and not entirely incorrect. While the majority of DUI cases are related to alcohol, a growing number of DUI arrests are related to drug use. These charges can involve both illegal and legal medications. Most people are aware that driving under the influence of an illegal substance like marijuana, cocaine, or methamphetamine can lead to arrest. But did you know that Henry County law enforcement officers can and do arrest people for driving under the influence of their lawfully prescribed medications or even over the counter medicines that they may be taking for allergies or a cold? A Henry Co. police officer is trusted to use his/her judgment in assessing if he/she thinks a driver may be under the influence of some type of drug. This is cause for some concern. Currently, there are virtually no studies correlating any illegal or legal drug with any negative impact on driving ability. In addition, the standardized field sobriety tests that most Henry County DUI officers use are not designed to test for impairment from drugs. Only a very small percentage of law enforcement officers have any significant training in detecting whether someone is under the influence of an illegal or legal drug to the extent it impairs their driving ability.
