Drug related DUIs can be even scarier than alcohol related DUIs.  For most types of drugs, Washington recognizes no legal limit.  Unfortunately, the DUI statute is also vague enough to include almost ANY kind of drug as a drug that can give rise to a DUI charge – regardless of whether the drug is a prescription or over the counter or whether or not it is taken according to a doctor’s instructions.  Many people in Washington are now being arrested for driving under the influence of prescription drugs like Ambien, Oxycodone, Oxycontin, and even drugs like Wellbutrin and Zoloft, or drugs like marijuana, sometimes in combination with alcohol or other drugs and sometimes alone.  One little pill can give rise to a real life nightmare.

When law enforcement obtains a warrant for a blood sample, the state often attempts to use the presence of drug metabolites as proof of driving under the influence.  This means that a person may have taken a medication or drug DAYS before an alleged incident and the prosecution might still try to use evidence of metabolites as proof that the person was under the influence.  Some drugs or substances may also cause blood tests to show false positives

Although drug related DUI prosecutions have been around for a long time, recently, law enforcement has shown an increasing tendency to arrest drivers for non-specified and non-traditional kinds of drug intoxication. Prosecutors often rely on law enforcement’s “Drug Recognition Experts” (DREs) to testify about their conclusions regarding drivers that they believe are under the influence. Local courts, however, put real parameters and limitations on the ability of officers to give conclusive testimony against drivers.  To effectively defend against these kinds of charges, Ms. Dalton constantly works to continue developing an in-depth knowledge of the scientific or quasi-scientific procedures used by police.


DUIs related to Ambien or Zolpidem are an increasingly common problem for drivers around the country.  The drug is often associated with the phenomenon of sleep driving.  A person will take the drug as a sleep aid and then with no knowledge of doing so, will find themselves behind the wheel with police at their window or in a ditch in the car in their pajamas.  The special nature of the drug makes it seem unfair to apply traditional strict DUI accountability.  Sometimes officers charge drivers for driving with prescribed drugs like Zoloft, Prozac, Paxil, Effexor, Oxycodone, Wellbutrin, Halcion, Lithium, and others, alone or in combination with alcohol.  There is no “legal limit” for these sorts of drugs and the level of intoxication alleged by the state can become a frightening guessing game with serious consequences.  Ms. Dalton has used cutting edge legal motions and an aggressive trial strategy to obtain superior results in these sorts of cases.

Drug DUI cases present special challenges and not all attorneys are equipped to handle the atypical scientific and legal issues related to legal and illegal drugs. Although Washington law is very specific as to the amount of alcohol that would definitively constitute intoxication (the “legal limit” of .08), Washington law is much less specific when it comes to drugs.  In fact, Washington is one of very few states whose drug DUI laws do not define specific drugs that will form a basis for a DUI charge, nor does the law specify what level of prescription or non-prescription drugs in a person’s system would be considered a level sufficient to constitute intoxication.  This is typically left up to the Washington State Patrol’s toxicology lab scientists who may rely on biased studies to form their conclusions.

New marijuana laws and recent changes in requirements for obtaining blood tests leave some new and untested areas in drug-related DUI laws.  We scrutinize legal requirements and look for productive ways to call into question the practices and procedures used to accuse drivers.  When new laws and procedures are used, Ms. Dalton works hard to make sure that they are not used against drivers in violation of their constitutional or other rights.  Nicole Dalton is an experienced and aggressive drug DUI lawyer and gets results.

Whether the ultimate goal is a good plea bargain or taking the case to trial and beating the charges, Ms. Dalton uses cutting edge, aggressive litigation to obtain the best possible results for her clients.
