Definition of Metabolite

Interviewer: What is a metabolite?

Brian Sloan: A metabolite is basically a byproduct of a parent drug. In the world of DUI, if someone has done some type of drug like cocaine, PCP, marijuana, or any type of medication, that medication will usually break down to a subset of drugs, which are considered metabolites, or the byproducts of the parent drug. When a drug is taken, it breaks down into metabolites before it is eventually eliminated from one’s system.

Detection of Metabolites

Interviewer: How are metabolites detected, first of all?

Brian Sloan: Well, it can be a metabolite of another drug or it can be a drug itself. For example, with marijuana, marijuana breaks down into the metabolite hydroxy-THC, which then metabolizes into what is called carboxy-THC. THC itself is impairing. Hydroxy-THC itself is impairing. Carboxy-THC is non-impairing.

Interviewer: Is that extracted through a Breathalyzer, through urine, or through blood?

Brian Sloan: It cannot presently be detected by way of a breath test. It’s usually done in a lab through blood or urine to detect the presence of THC or the metabolite carboxy-THC. Labs were not checking in a person’s blood or urine for the presence of hydroxy-THC because hydroxy-THC does not last very long in a person’s system – usually only a couple of hours before it metabolizes into carboxy-THC. With the new ruling that came out from the Arizona Supreme Court, it’s possible that prosecutors are going to talk to the labs and see if they can actually test for the presence of hydroxy-THC to see if there is still an impairing metabolite of marijuana in a person’s system.

“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.
