What Drugs Are Commonly Attributed to Drug-Related DUIS?

Interviewer: What are the most common types of medication that you are seeing attributed to drug-related DUIs?

Brian: A lot of Ambien, a lot of Zoloft, and Carisoprodol.  Now we’re seeing more marijuana under Arizona’s Medical Marijuana Act, which is arguing is the impairment on par with a prescription medication if it isn’t considered a prescription medication itself.  Anything that’s impairing is also prescribed.

Arizona Lists Hundreds of Drugs as Having Impairing Properties

The state of Arizona lists hundreds of types of drugs that it considers illegal substances or impairing substances.  Almost anyone who’s taking medication can fall into one of those categories, including the people who are taking Adderall for their ADD.  Adderall is considered a type of drug that can cause impairment.

Over-the-Counter Drugs Can Also Have Impairing Properties

Interviewer: What about over-the-counter medications like Nyquil?  I know if I take Nyquil I’m pretty woozy afterwards.

Brian: Nyquil can contain alcohol.  Lots of medications contain alcohol and many medications can contain drugs that can lead to impairment.  There is one over-the-counter medication that can even result in methamphetamine appearing in your system.  You’re never really safe and it really needs to come down to if you feel that you are impaired by whatever.  If you eat a banana and you feel that you’re impaired, you don’t drive.

Do Medications Remain in One’s System Longer than Alcohol?

Interviewer: How long did medications stay in one’s system generally?

Brian: Arguably, medication and the metabolites of the medication can always be in someone’s system.  If they are taking medication daily, the combination of the active ingredient of the medication and the metabolites can always be present in a person’s system.

Drug-Related DUIs Are More Defensible than Alcohol-Related DUIs

I will say that medication DUI cases tend to be much better at trial.  I have gone forward I think on every one of my medication DUI cases, I’ve been able to convince the jury to find my client not guilty.  They are generally better cases to go to trial, but unfortunately, they tend to be the type of cases that really need to go to trial.

I’d say on just about every one of my medication DUI cases, I have attempted to convince the prosecutor just to dismiss the case out right. Usually they refuse to do it, but when you put it in front of a jury and you put it in front of members of the community who probably take medication themselves, they understand that first; people need to take their medications.  They understand the concept of, “This person’s been on this medication for ten years, hasn’t had any problems before.  Why all of a sudden are they being arrested for DUI now?”  It tends to be a much better argument in front of a jury than something like alcohol DUIs.

“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.
