If you are facing charges for driving under the influence (DUI) of marijuana, contact a Seattle marijuana DUI lawyer right away. Marijuana DUI law is complex and controversial in the state of Washington. Due to the peculiarities and nuances of tetrahydrocannabinol (THC), you could have a THC blood concentration over the legal limit without being impaired. This is particularly common if you are over 21-years-old and regularly use medical and recreational marijuana, which is legal in Washington.

Washington Marijuana DUI Laws

Most states, Washington included, have provisions for DUI charges based on drug-related impairment. Under Washington DUI law, Revised Code of Washington (RCW) 46.61.502, you can be found guilty of a DUI if you drive a vehicle within the state and you:

  • Are under the influence of or affected by an intoxicating liquor, marijuana, any drug, or any combination of these;
  • Have a blood alcohol concentration (BAC) of .08 percent or higher within two hours of driving; or
  • Have a THC blood concentration of 5.0 or higher within two hours of driving.

Additionally, RCW 46.61.504 states you can be charged and convicted of a crime if you are in actual physical control of a vehicle while intoxicated by alcohol or a drug in Washington. If within two hours of being in actual physical control of a vehicle, other than driving, you have a BAC of .08 percent or higher or a THC concentration of 5.0 or higher then you will be charged. You can also be charged with a crime if you are in actual physical control of a vehicle while under the influence or affected by a liquor a drug.

When You May be Charged with a Marijuana DUI

What do these laws really mean? It is clear that you can be arrested and charged with a DUI if you have a specific amount of THC in your blood when you are driving or are in actual physical control of a vehicle, which can mean many things like you are sitting in a running vehicle or are in the vehicle and have the keys within reach. There are also situations that are less black and white. You can be arrested and charged with a DUI if the officer observes signs of drug-related impairment when you were driving or in actual physical control of a vehicle.

Ultimately, if the officer believes you are high, you may be arrested. Even if a blood test comes back with a THC concentration less than 5.0, you could still be charged. Prosecutors will move forward with marijuana DUI charges if they believe they have enough evidence without a THC concentration above the legal limit to win a conviction.

Underage Marijuana DUI

If you are under 21 years old, then a different standard applies to you while driving. Based on RCW 46.61.503, you can be arrested for a DUI if you have a BAC of .02 percent or higher or have any THC in your blood within two hours of driving. Adults over the age of 21 can have a THC concentration up to 4.0 and potentially escape DUI charges. However, any detectable THC in your blood when you are underage can have serious consequences.

THC Concentration Controversy

The legal THC limit is controversial for many reasons, including that a specific THC level does not correlate to impairment, and the amount of THC that remains in a person’s blood is highly individual.

While alcohol is water soluble, THC dissolves in fat. It moves very quickly from a person’s blood stream to their fatty tissue, which includes the brain. This means the amount of THC in a person’s blood does not equate to a specific level of impairment. A person can be high with a low THC blood concentration and not inebriated with a higher THC blood concentration.

There is a general window for when alcohol will remain in your system and for how long, yet there is no typical timeframe for THC. The amount of THC that remains in a person’s body after having smoked or ingested a THC product varies a great deal based on the individual. This is a significant issue for regular marijuana users. The occasional user may expect the drug to be mostly out of their system in a few hours. However, if you are a regular marijuana user, your body will continuously have higher THC levels. A blood test conduct by the police could detect a considerable amount of THC hours or days after you imbibed. Depending on how often you use marijuana, the amount of THC you last consumed, and a variety of lifestyle factors, you could have a THC concentration of 5.0 despite not having smoked or consumed a THC product recently.

Penalties for Marijuana Related DUI Convictions

If you are charged with a marijuana DUI, you will face a gross misdemeanor, punishable by

  • Up to 364 days in jail
  • 15 days of electronic home monitoring (EHM)
  • Up to a $5,000 fine
  • 90-day driver’s license suspension

Depending on the situation, you may also be ordered to participate in a drug assessment or counseling or complete community services. You can also expect your punishment to extend beyond the statutory penalties.

A conviction for a gross misdemeanor creates a permanent criminal record that can lead to:

  • Difficulty getting into college
  • Difficulty obtaining financial aid, including grants and scholarships
  • Ineligibility for or difficulty obtaining certain professional licenses
  • Difficulty getting a job or moving up in your career
  • Difficulty being approved for an apartment
  • Effects on your immigration status, including a visa, permanent residency, or citizenship
  • Difficulty traveling abroad, including to Canada

Is Medical Marijuana a Defense?

If you use marijuana to treat a medical condition and have been charged with a marijuana DUI, contact us immediately. Medical marijuana is not an affirmative defense under Washington law. However, it may be an important factor in your case. When you have been charged because of having a THC concentration over the legal limit in your blood, yet this is likely due to your consistent, medical-related use and not due to inebriation at the time of the traffic stop, then we will aggressively fight for the charges to be dropped. If prosecutors move forward with charges, we will put forward evidence that you were not impaired at the time of the traffic stop.
