Snohomish County Drug DUI Lawyer 

Comprehensive Drug DUI Legal Support in Washington State 

The crime of driving under the Influence (DUI) also includes driving while impaired by drugs. Drivers can be charged with a DUI involving drugs for the use of illegal substances as well as prescription drugs. Most DUI cases involving drugs are based on the subjective evaluation of the arresting officer. Recently, law enforcement has begun using drug recognition experts who have been trained to evaluate DUI drug suspects.

What are the Penalties for a Drug DUI in Washington? 

Penalties in a DUI drug case are similar to cases involving intoxication. They include:

DUIHeroes is a world-class DUI firm providing effective representation to clients charged with a DUI that involves drugs. Our founder is a proven DUI attorney in Snohomish County who has pursued extensive DUI training through the National Highway Traffic Safety Administration—the same courses taken by police. Our trial team also includes former prosecutors, giving us inside knowledge about how the state will likely attempt to prosecute. Our firm aggressively challenges DUI test results and subjective assessments of a person’s alleged drug impairment, earning us a 90% case average getting DUI charges dismissed or reduced.

Defense for Drug DUI Charges 

In Washington, you can be charged with a DUI for drug impairment if you have at least 5 nanograms (ng) of THC per liter of blood in your system at the time of blood testing, which must be done within two hours of driving. Like the 0.08 blood alcohol concentration (BAC) limit for DUI arrests based on alcohol intoxication, the 5 ng THC limit is seen as a baseline to justify an arrest and charges—but it can also be the starting point for a defense strategy from a team as skilled as ours. At DUIHeroes, we craft proven defense strategies that challenge every weakness in the prosecution’s case, which could include any drug test results being leveraged as justification for your arrest.

Depending on our investigation, we may be able to argue that the blood test was conducted incorrectly, the sample was stored improperly, or the results were interpreted erroneously. After all, detecting 5 ng of THC in a person’s bloodstream is a procedure that requires precision and expertise. If there is any sign that the process was not done perfectly, we can discredit the evidence and argue for its dismissal. It might even be possible to defend you by proving that the result showed less than 5 ng/liter of THC, so the charges were never justified.
