Is a Prescription for Marijuana Use a Defense for a DUI Charge?

Interviewer: We’ll talk about medical marijuana.

Brian: Medical marijuana is not a prescription medication. There’s an interesting concept that’s going around. I’ve subscribed to this concept where the law specifically says, as it refers to DUI’s, “That if you are taking medication that is prescribed by a doctor and you’re taking it as prescribed, that can be a defense to help to a DUI, if you were driving and had any drugs or its metabolite in your system.”

The thing about marijuana is that even though the law has passed personal marijuana usage for medical purposes, and a doctor “recommends” marijuana use, the belief has always been that marijuana is not a prescription medication.

However under Arizona revised statute 28-1381b, “A person using a drug as prescribed by medical practitioner is not guilty of violating DUI laws of having any drug or metabolite in your system.”

The statute does not say a prescription drug. The statute says a drug prescribed. Now, if you look in the dictionary, there is a difference between the definition of the word prescription, and the definition of the word prescribed. When a doctor issues a prescription, it is for a legal form of medication.

That’s why they cannot issue a prescription for cocaine. They cannot issue a prescription for PCP, for example.

Is a Prescription a Legal Authorization?

However, when a doctor makes a recommendation for marijuana, technically they are prescribing marijuana. If you look up the definition of the word prescribed, prescribed means a prescription or a recommendation.

A doctor can prescribe medication just in the same way that they can prescribe that you go home and get eight hours of sleep. They can prescribe that you eat two apples a day. They are not literally giving you a prescription apple and they are not giving you prescription sleep.

They are making a recommendation that you do something for your medical benefit. And it therefore is qualified as prescribed. It’s not prescription but it’s prescribed. There does seem to be a difference.

Under this law which is a defense to DUI, it’s arguing that there’s a difference between the word prescription and the word prescribed, the word prescription and prescribed does not show up in Arizona’s medical marijuana logs. If a doctor recommends it, then that recommendation should be fall under the definition of prescribed. This then is a valid defense is for a DUI of driving with any drug or its metabolite in your system.

Interviewer: When did you discover this? Have you brought it to bear yet in the defense?

Brian: I haven’t had the right case yet to bring it up. In talking with another attorney who is a member of the AZ DUI team. He basically enlightened me about this idea.

I was always under the impression that you can’t do anything with the marijuana as a prescription argument because it was specifically kept out from being called a prescription. After thinking about what he said, I agree with him that there is a difference between “prescription” and” prescribed.”

What Do You Receive When You Have a Medical Recommendation for Marijuana?

Interviewer: When you see a doctor, are they giving you a piece of paper that is technically not a prescription? Are they giving you a recommendation? What exactly are they giving you?

Brian: It’s not going to be on a prescription form. I believe it is going to be a letter. If there isn’t a letter, you are not allowed personal use of marijuana. It does have to be recommended by a doctor.

Usually when the issue comes up it’s always a matter of, “My friend has prescription marijuana and he just shared.” Or “I have a prescription marijuana card but I got it after I was arrested for DUI.” Or “I had a prescription marijuana card but it expired.” I haven’t quite had the right case yet in which to debut this defense.

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

I have spent my entire career focused on DUI Defense representation, having personally defended more than 4,100+ DUI clients in the past 18+ years.

If you’re looking for a divorce attorney, tax attorney, or civil attorney, then I can comfortably say: "I’m not the one for you".

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 that is what they think people want to hear. The truth of the matter is, being "aggressive" rarely gets the client anywhere in these court systems. Being "aggressive" isn’t the same as being good, and is often used to put on a show for a client to hide the fact that they aren’t doing anything meaningful for the client.

The same is true for the lawyers that claim to do DUI Defense... and Criminal Cases..., and Accident cases..., and Divorces. A Jack-of-all-Trades is a master of none. By handling all different 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.

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

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

I am one of the most award-winning DUI Defense Lawyers in Arizona; have been recognized nationally, including in a 2022 issue of USA Today; and there are only a few lawyers in Arizona who have personally defended more DUI cases than I have. I am also one of the most reasonably-priced DUI Lawyers, as I pride myself on charging a Flat Rate only for the legal services you need, and not for the legal services you don’t.

I am also the lawyer who people call once they realize that their original lawyer screwed something up, gave them false hope or false promises, or simply just took their money and didn’t do much on the case. You would be surprised at how often this happens.

Save yourself the trouble of hiring the wrong lawyer, and hire the right DUI Defense Lawyer from the start.
