What Counts as a Drug DUI in Washington?

Under RCW 46.61.502, it’s illegal to drive while “under the influence of or affected by” any drug. This includes:

• Illegal substances, such as methamphetamine, cocaine, heroin, or LSD
• Prescription medications, like painkillers, anxiety medication, or sleep aids
• Marijuana (THC), even if legally obtained

Many drug DUIs depend heavily on officer observations and blood test results. Officers trained as Drug Recognition Experts (DREs) are often called in to assess drivers suspected of being impaired by drugs. However, these evaluations are not always accurate. Many prescription drugs can mimic impairment symptoms, such as drowsiness, unsteady balance, or slow speech, even when taken as directed. That’s why it’s critical to have a lawyer who knows how to challenge these assumptions and expose weaknesses in the state’s case.

What Are the Penalties for Drug DUI in Issaquah?

A conviction for a drug-related DUI in Issaquah carries penalties similar to those for alcohol-related DUIs. 

While the exact consequences depend on various factors, including your prior record (if any), common penalties include:

• Jail time and/or probation
• Fines and court costs
• Driver’s license suspension
• Mandatory drug treatment or counseling
• Chemical dependency evaluations
• Community service or ignition interlock requirements

These penalties can increase sharply with prior DUI convictions or aggravating factors, such as having a minor in the vehicle or causing an accident that leads to injury or death.

In addition to legal penalties, the personal consequences can be just as severe. A drug DUI conviction can affect employment, housing, insurance rates, and your reputation. That’s why it’s vital to have a drug DUI defense attorney in Issaquah who can protect you from both the immediate and long-term effects of a conviction.

Marijuana DUIs: The 5 Nanogram Rule

In Washington, drivers can be charged with DUI if they have 5 nanograms (ng) or more of THC per milliliter of blood. This threshold was established under Washington’s legalization laws, but it’s not as straightforward as it sounds.

THC can remain in the body long after impairment has passed. A person can test above the legal limit hours or even days after using marijuana, even when they are no longer impaired. Blood testing is also prone to collection and storage errors, which can distort results.

At DUIHeroes, we know how to challenge the science behind THC testing. We analyze lab procedures, chain of custody records, and the qualifications of those performing the test. If there’s any sign of improper handling or interpretation, our Issaquah DUID attorneys can fight to have that evidence excluded.

Common Defenses to Drug DUI Charges

No two DUI cases are the same, but many rely on the same flawed assumptions. Our Issaquah drug DUI lawyers use advanced defense strategies that question every part of the prosecution’s case.

Some common defenses to these types of charges include: 

• Challenging DRE Evaluations: Drug recognition assessments are subjective and often based on guesswork.
• Reviewing Blood or Urine Test Procedures: Improper storage, handling, or timing can lead to unreliable results.
• Questioning Probable Cause: If you were stopped or arrested without a valid reason, evidence gathered afterward may be inadmissible.
• Lack of Impairment: Many medications can cause physical side effects that mimic impairment, even when taken legally and responsibly.

We’ve spent years studying how police conduct drug-related DUI investigations—and we know how to find mistakes that can make or break a case.
