Don’t Let One Mistake Derail Your Future—Arizona DUI Drugs Lawyer

If you are pulled over by a police officer while driving with any measurable amount of drugs or the metabolites of drugs in your system, you may be charged with DUI drugs if you were in actual control of the vehicle.  Unlike DUI involving alcohol, a DUI drugs charge may be brought even if there are only trace amounts of the drug or drug metabolite in your system.  It is even more problematic that blood or urine testing may well show that you have drug or drug metabolites in your system, even though the metabolites are showing up because you used a substance like marijuana more than a week earlier.

If you are stopped and the officer asks you to perform field sobriety tests (FSTs), take a blood or urine test or finds drugs within your vehicle, it is imperative that you seek the advice of experienced Tempe DUI drugs lawyer Dianne Sullivan immediately.  Ms. Sullivan is intimately familiar with appropriate police investigative practices and the range of plea negotiation options and prosecution strategies in DUI drug cases. This experience derives not only from her own experience defending those accused of DUI drugs throughout Maricopa County but also from her time as a prosecutor with a high conviction rate in DUI drugs cases.  Ms. Sullivan uses this insider knowledge to build the strongest possible defense in your DUI drugs case.

We may use a ride range of defense strategies depending on the specific circumstances of your DUI drugs charge. Often Ms. Sullivan challenges the legal sufficiency of the initial stop of your vehicle.  A law enforcement officer may not stop your vehicle on a mere hunch. The officer must have observed you engaged in committing an unlawful act or have reasonable suspicion based on articulable facts that you were engaged in illegal activity.  If the officer does not have sufficient specific facts to justify your initial stop, Ms. Sullivan may seek to have all evidence that flowed from your DUI investigation suppressed.  This may mean that any evidence of the officer's observations at the time of the stop and field sobriety test results as well as blood and urine test results are all excluded, which means that the prosecutor may be forced to dismiss the charges.

Even if the basis for the stop was legally sufficient, Ms. Sullivan will carefully evaluate any blood or urine testing and may challenge the accuracy and reliability of the test results.  Ms. Sullivan frequently uses forensic experts to testify regarding issues with blood or urine testing, which may range across a broad spectrum of potential issues, such as contamination of the evidence or whether the test is an accurate indicator that you were driving under the influence of drugs.

If the officer confiscated drugs during your stop from inside your vehicle or on your person, we may be able to challenge whether the search violated your Fourth Amendment right against unlawful search and seizure.  If the officer pulled you over for speeding, for example,  this in and of itself is not evidence that you were driving while under the influence of drugs.  If the officer cannot point to other evidence that justified a search of your person or vehicle, Ms. Sullivan may be able to file to have the illegal drugs or paraphernalia excluded from your criminal case. However, it is never a good idea to have illegal drugs or paraphernalia within the passenger compartment of your vehicle because it if these illegal items are within the plain view of the officer during the stop this is an exception to the warrant requirement for unreasonable search and seizures.
