Arizona Utilizes Drug Recognition Experts

Interviewer: In terms of the traffic stop under suspicion of DUI, does Arizona have DREs, Drug Recognition Experts?

Brian: Arizona does have Drug Recognition Experts. Anytime the officer suspects that drugs or medications may be involved, usually because they’ve ruled out alcohol but they do see some form of impairment, they can call out an officer that has some training in drug recognition.

The Officers are Utilized When Alcohol Impairment Has Been Ruled Out

The officer will either come to the scene or the suspect will be brought to where this drug recognition expert is. The drug recognition expert will do these tests testing the eyes, testing pupil size, testing reaction to light, and will go through a series of questions.

DREs Will Most Typically Ask You About Your Drug Use

Usually the most common one that the drug recognition expert asks is, “Have you taken any drugs?” Usually a suspect will say, “Yes, I took cocaine three hours ago.” That tends to be what the drug recognition expert puts down as, “I believe this person has been impaired by cocaine.”

During a situation that was handled by another attorney, a person was arrested and was before a drug recognition expert and the question came up, “Have you taken any drugs lately?” The person said, “Yes, I’ve taken cocaine.”

The drug recognition expert wrote that down and said, “I believe this person is under the influence of cocaine. That is my scientific evaluation.” Later, when they tested the blood, there was absolutely no cocaine present but the person did have marijuana present.

The question became why did you say that you had cocaine if you did not have cocaine? The answer was, “I was just fooling with the officer.”

These drug recognition experts really wait until the person admits to doing it and then they say in their medical opinion, or their expert opinion, that the person is under the influence of the drug that the person admits to taking.

If You Are Arrested, You May Not Know You Are Being Questioned By a DRE

Interviewer: Will people know when they are encountering a DRE, for example, do they dress differently? Do they let people know they are a DRE?

Brian: I’m not sure if they actually introduce it. Usually, as part of the drug recognition exam, the police will take a suspect into a darkened room. The typical scenario is to have one or two officers in a dark room with the suspect.

One of these officers is usually a drug recognition expert, and they’re all three sitting there or standing there in a dark room. Then the drug recognition expert turns on a flashlight to see how the suspect’s pupils react to light.

“I am one of only a handful of Phoenix DUI Lawyers that focuses solely on DUI Defense representation.”

I have spent my entire career SOLELY focused on Arizona DUI Defense Representation, having personally defended more than 4,400 Driving Under the Influence (DUI) clients in the past 19+ years.

If you’re looking for a Divorce Attorney, Tax Attorney, Civil Attorney, etc., I can comfortably say, "I’m not the one for you." I ONLY defend DUI cases in most of Maricopa County, Arizona.

Coming up with traditional, as well as outside-the-box motions and defenses for my clients, often with good results, is the hallmark of my practice.

Lawyers that say they are "aggressive" or "will fight for you" are a dime a dozen. They use these phrases because it is a proven advertising phrase. Being "aggressive" isn’t the same as being good, and is often used to put on a show to hide the fact that they aren’t doing anything meaningful for the client.

The same is true for the Lawyers claiming to do DUI Defense, and Criminal Cases, and Accident Cases, and Divorces, etc. A Jack-of-all-Trades is a master of none! By handling all sorts of cases, they take away from their ability to truly focus on DUIs, and keep up-to-date on the latest changes in DUI Defense Representation.

What I offer is intelligent, quality DUI Defense at an exceptional price. Unlike many other law firms, if you hire The Law Offices of Brian D. Sloan, you actually get me representing you, doing all the work, and working the case. You aren’t hiring one guy with all the experience, but getting the underling with very little knowledge or experience.

I work seven days a week on my client’s cases, and spend hours laying all my thoughts out for my clients in writing, so they can understand their options, and my recommendations. No other DUI Lawyer in the state does this. I try to do what I can to go above-and-beyond for my clients. I hate when the businesses I deal with nickel-and-dime me with hidden costs, and I take pride in not doing that to my clients.

I have not only taught other lawyers how to do DUI Defense Representation at statewide seminars, but I have produced DUI Legal Guides used by defense lawyers across Arizona.

I am one of Arizona's most award-winning DUI Defense Lawyers, as well as being recognized nationally. I was the only DUI Defense Lawyer in the United States named a "Power Lawyer" in a 2022 issue of USA Today

There are no other private Lawyers in Arizona that have personally defended more DUI cases than I have. And as a bonus, I offer a very reasonable flat rate for my legal services, with a payment plan, and without any hidden charges. This guarantees that I offer some of the most competitive rates among all Arizona DUI Attorneys, while being a well-documented and preeminent leader in the field of DUI Defense Representation.

Over the years, countless people have come to me after discovering that their first lawyer made a mistake, gave them false hope or false promises, or simply took their money and didn't do much to advance their case. And you would be surprised at how often this happens.

So, instead of wasting time and money on the wrong DUI Defense Attorney, do yourself a favor and get the proven and well-recognized best DUI Lawyer in Phoenix and the surrounding areas of Maricopa County.

You can reach me on my personal cell phone at 480-720-7839 for a Free ‘In Depth’ Consultation.

I personally defend DUI cases in urban Maricopa County City, Town, and Justice Courts, including:

Ahwatukee / Agua Fria / Arcadia Biltmore / Avondale / Buckeye / Chandler / Country Meadows / Desert Ridge / Dreamy Draw / Downtown / East Mesa / El Centro / Encanto / Gilbert / Glendale / Goodyear / Guadalupe / Highland / Kyrene / Litchfield Park / Maryvale / McDowell Mountain / Mesa / Moon Valley / North Mesa / Peoria / Phoenix / Queen Creek / San Marcos / San Tan / South Mountain / Scottsdale / Tempe / University Lakes / West McDowell / West Mesa / White Tank

For any other Courts in the State of Arizona, including Felony cases, I would recommend my associates on The Arizona DUI Team, whom I work closely with, but I am not the one personally representing the client.
