In West Virginia, a marijuana DUI charge carries much of the same weight as an alcohol related DUI in the state. Like alcohol, marijuana can impair drivers operating motor vehicles and heavy machinery while under its influence. What makes marijuana DUIs trickier is that there is no quick or precise way to test for intoxication. If you have been arrested for a marijuana related DUI, a Morgantown marijuana DUI lawyer can assist you.
At Crowe Law, we understand the long-lasting impact a marijuana DUI can have on your driving record, employment status, and personal life. West Virginia is unique in that the state’s marijuana laws differ from those of certain cities, like Charleston, where it is decriminalized.
Confusing jurisdictions can make cannabis consumption complex for citizens, especially those who utilize it for medical purposes. To better understand your rights, hire a marijuana DUI lawyer today.

Unlike alcohol, marijuana does not have a breathalyzer test that can be administered quickly or on the scene to prove a legal limit. Instead, arresting officers must prove not only that marijuana was consumed, but that it was the cause of your impaired driving. Field sobriety tests and physical signs like red eyes or a dry mouth can be used as suspicion, but do not alone prove marijuana impairment. Instead, police rely on blood and urine tests to prove cause.
Through these blood and urine tests, law enforcement can prove impairment if even 3ng/ml of THC is detected, via “Per Se” evidence recognized in West Virginia. It makes sense that penalties can be extreme for marijuana DUIs when over 40% of drivers who are involved in fatal car accidents are found with THC in their system.
The penalties for a first offense or misdemeanor marijuana DUI in Morgantown include:
Penalties for a second offense within ten years include:
Penalties for a third or subsequent offense within ten years include:

In a marijuana DUI case, the goal of your attorney will be case dismissal or reduced penalties if dismissal is not a realistic goal.
In 2026, West Virginia introduced new and updated laws concerning DUI offenses. Baylea’s Law increases the minimum and maximum prison sentences and doubles the fines for fatal DUI accidents. Drivers who are caught driving with an extreme blood alcohol content of .16% or higher might get a mark on their physical license, prohibiting the purchase of alcohol where ID checks are mandatory.
Stricter bail for second or subsequent DUI offenders was issued to force judges to consider substance dependency risks.
Yes, driving while under the influence of marijuana is still considered a DUI, even if the marijuana is prescribed and used for medicinal purposes. While there is no universally accepted limit to operate a motor vehicle on marijuana, sobriety can only be tested through blood, urine, or saliva tests that cannot be taken at the site of the stop. Instead, law enforcement will use field sobriety tests, such as red eyes, smoke odor, and other physical symptoms, to prove impairment.
While patients who have a state-issued medical card and towns like Charleston have decriminalized it, recreational marijuana is still illegal in West Virginia, and possession of any amount is considered a misdemeanor.
The first offense for possession of marijuana without a medical card in West Virginia can result in a minimum of 90 days or a maximum of 6 months in jail, and fines no more than $1,000. Speak with a Morgantown marijuana DUI attorney to discuss your case.
In West Virginia, drivers can be charged with a “per se” DUI if 3ng/ml or more of THC is detected in their blood. Police test for marijuana through a mix of physical and chemical testing. Roadside tests like the walk-and-turn are used for immediate testing, along with blood or urine tests that can be completed within hours of arrest. West Virginia police also use saliva screening that can be implemented at the scene and gives results within 5 minutes.
Do not let a night behind the wheel put your job, your family, or your recreational time on the line. Marijuana laws have evolved over the last decade more rapidly than in the past, and these charges do not necessarily have to result in extreme ramifications.
