Drunk driving is known to be dangerous, and drivers understand that they can face criminal charges of driving under the influence (DUI) if they operate a motor vehicle with a blood alcohol concentration (BAC) above the legal limit of .08%. However, some people may not realize that they can also face DUI charges if they drive after using other types of drugs or intoxicating substances. Driving while under the influence of marijuana has become a larger concern for law enforcement in recent years, especially since several states have made this drug legal for both recreational and medical uses. While marijuana remains illegal in Tennessee, some people may travel to other states where it is legal, and drivers will want to understand the potential consequences they could face if they are charged with DUI related to marijuana or other drugs.
Drug-Related DUI Charges
Under Tennessee law, it is illegal to be in physical control of a vehicle on a public road or highway while under the influence of marijuana, controlled substances, drugs that affect the central nervous system, or other types of intoxicants. A person will be considered intoxicated if a substance or a combination of different substances affects the clearness of their mind and their self-control, causing them to be unable to operate a vehicle safely.
DUI charges related to marijuana or other substances are charged the same as for a driver who is intoxicated by alcohol. If a chemical test shows that a driver has any amount of marijuana or illegal drugs in their system, they may face DUI charges. A person may also be charged with DUI if they use prescription drugs such as opioids that impair their driving ability, or even if they use over-the-counter drugs such as cold or cough medicines that cause drowsiness or affect their clarity of mind.
