To Mitigate Arizona’s Strict Penalties, it Is Important to Retain an Attorney

Interviewer: That law makes absolutely no sense.

Brian: Exactly. That’s why it is important to have an attorney. The ignition interlock device only tests for alcohol, it has nothing to do with drugs, illegal or legal.

Arizona law requires an interlock device on any vehicle if the driver is convicted of a DUI unless you know what you’re doing and how to ask to successfully to prevent an ignition interlock device from being ordered.

Interviewer: If you know someone who uses medical marijuana, do they need to report that to anyone? Or does having a card a become liability to you because it can show up in public record and be used against you?

Brian: There has to be some evident of marijuana use to warrant a charge. Simply having a card that allows you to use medical marijuana isn’t going to be enough. The prosecutor has to prove that is was present in your system.

Possession of a Medical Marijuana Card Will Not Result in a Count Two Charge

They do that by way of a blood test or urine test. Possessing a medical marijuana card, even though there are issues with medical marijuana being “recommended” and not prescribed many times a prosecutor’s office will determine that is do not warrant a charge count two–that you were driving while you had any drug or its metabolite in your system.

I think they realize that this is an issue with the law. They do realize that it is unfair to have the state of Arizona and a doctor recommend that you take medical marijuana for medical reasons and then charge someone for simply having it present in their system.

I think that’s an ethical issue for the prosecutor. Some prosecutors won’t charge it, others will but you still have to deal with the issue of impairment.

Interviewer: If you’re involved in a traffic stop and you have a medical marijuana card and the police see it or you give it to them, would that give them probably cause to draw your blood?

Brian: It shouldn’t but the officers know what they are doing and they know to say, “Well, I noticed blood shot, watery eyes, well, the person admitted to smoking marijuana an hour earlier.” They’ll find a way to obtain blood.

Possession of a Medical Marijuana Card Is Not Adequate to Establish Probable Cause

But simply because the person has a medical marijuana card on them is not probable cause to believe that they have consumed marijuana nor that they have used marijuana so they would not be able to get access to the blood or urine.

For example, before the medical marijuana laws came into effect I had a client who was pulled over and they discovered that he had marijuana in his backpack.

After discovering marijuana in his backpack, the officers decided to draw his blood, figuring that if he has marijuana in his backpack he must have ingested marijuana.

We were right on the verge of getting that blood test result suppressed because there is no reason to believe that simply because one has it in a backpack that they have it in their system. It’s the same thing with the medical marijuana card.

If you have a medical marijuana card, without more evidence, the simple possession does not indicate that someone has marijuana in his or her system or that they are under the influence of marijuana.

Interviewer: Is it the same as if someone went to a smoke shop it, doesn’t mean that they used any of the products inside of the shop in an illegal way?

Brian: It is the same analogy: Simply someone walking into a bar doesn’t mean that they are coming out drunk.

“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.
