Marijuana DUI/DWAI Defense Attorney in Denver, Colorado

Receiving a DUI or DWAI for drugged driving is not a new concept. Each state has laws discouraging people from using motor vehicles while under the influence of alcohol, prescription drugs, or illegal drugs. Colorado is no different.

Understanding Colorado’s Marijuana DUI/DWAI Limits

Colorado finds itself in a unique position regarding drug-related DUI/DWAI charges. As only one of two states with legal marijuana, the Centennial State needed to establish a blood level limit of active THC. The limit was needed to help police determine if a person is “too stoned to drive.”

To determine if a motorist is under the influence, the limit for Delta 9- Tetrahydrocannabinol (THC), the active compound in marijuana, was set at 5 nanograms per milliliter of blood. Five nanograms or higher results in a marijuana-related DUI charge and below 5 nanograms can result in a DWAI charge.

Five nanograms per milliliter is not a large amount by any stretch of the imagination. A nanogram is equal to 1 billionth of a gram. To illustrate just how small that is, consider this: a paperclip weighs one gram. Slice that paperclip into one billion equal pieces. Each slice is equal to one nanogram- Colorado has deemed five nanograms to be the legal limit per milliliter of blood. A milliliter being equal to 20 drops of liquid. That wouldn’t be enough to fill your tablespoon half way.

Testing Methods and Controversies Surrounding THC Levels

There are four different types of tests used to detect the use of marijuana, but only a blood or saliva swab detect active Delta 9 – THC. Urine and hair drug tests only detect the byproducts left by your body breaking down THC. This limits law enforcement’s testing options to a saliva or blood test. A blood test is the most common marijuana drug test Colorado law enforcement officers use.

The saliva test allegedly detects the THC level and the recency of marijuana use. Yet saliva testing isn’t being widely used, leaving the blood draw as the most common test. Blood testing provides police with accurate THC levels, but that is where the controversy lies in this matter.

Opponents say the law is unfair to habitual users and those with medical marijuana cards. Since THC stays in the body longer, habitual users are in constant violation of current marijuana DUI laws. Denver area pot critic “William Breathes,” wrote how long marijuana stayed in his system. Breathes, a self-admitted daily user of marijuana, abstained from marijuana for three days. He then submitted to a blood test. The results showed a THC level 3 times the legal limit in his system, even after 72 hours. You can read his post here.

The law can change in the future. After more research on marijuana and impairment, politicians could change the legal limit. Case rulings can also alter the way the law is applied, but any change through those methods will be slow coming.

Seeking Legal Help After a Marijuana DUI/DWAI Charge

Regardless of whether you agree with the limit or not, it is the law in Colorado on marijuana-related DUI/DWAI charges. Colorado residents using marijuana should not get behind the wheel. Even if they “feel fine,” or think the effects have worn off, it’s in everyone’s best interest if someone else drives. If that’s not an option, a bus or cab ride would also be cheaper than a DWAI/DUI charge.

Yet, we’re all human and we all make mistakes. A DUI/DWAI charge for marijuana or alcohol is an dangerous and expensive mistake. DUI/DWAI laws are not forgiving to those who are charged with violating them.

But this type of mistake doesn’t make you a bad person. We’re all human and should be treated like such. That’s where Wolf Law is different from other criminal defense attorneys in Colorado.

The BEST person to have at your side

When I sat in my car that day, fear twisting into nausea, frantically scrolling through an endless sea of lawyer ads. I had no idea who to trust. I chose Jeff. He looked like an angry guard dog—and in that moment, I needed that.

Over the next three years, I learned he was far more than that. He never gave false hope; anything he told me, he could defend. I paid him once—one upfront fee—and he stayed with me the entire three years. He called with updates, stayed on top of every detail, and fought for me at every turn.

I can’t say your case will be like mine, but the fear and terror I lived with for three years were dramatically reduced by having Jeff in my corner. I’d never been in a legal situation before. He guided me with expertise, calmness, and total honesty. Looking back on that version of me frantic, in my car, hiring Jeff Wolf was one of the best decisions I’ve ever made.

And that angry guard dog look? It hides a genuinely warm and caring person.

Red Rocks Amphitheater – July 2025

Wolf Law was outstanding. Jeff was prompt, professional, and thorough from start to finish. He answered all my questions, did the necessary due diligence, and ultimately got my case dismissed. I’m extremely grateful to Jeff and the entire Wolf Law team. Highly recommend.

Professional. Attentive. Experienced. Successful.

I was referred to Jeff by one of my friends who was recently represented by Wolf Law in his DUI case; I will be forever grateful for that recommendation. Jeff made this extremely stressful process feel much more manageable from start to finish. He was always responsive and highly communicative, even throughout my barrage of anxiety driven questioning. He was a maestro in the courtroom and was able to get me the absolute minimum penalties. He even got certain areas of my very unique case dismissed – saving me thousands of dollars in the process. While I hope I never have to, I will surely be recommending Wolf Law as DUI representation to any of my friends and family in the future.

Very confident and competent attorney! I am very happy with Jeff

I contacted Jeff Wolf after I had some family issues that also carried potential criminal charges. I spoke with him as soon as i realized how severe the situation could be and he offered great legal advice that lead to me bringing him on as my personal attorney. The charges against me were dropped and I never had to go to trial but throughput the entire process Jeff was in touch and taking care of everything I needed. I am very happy with his services and would certainly work with him again if I was in the situation.

Worth every penny. Wolf Law at your side.

Wolf Law LLC is an exceptional law firm that I would recommend to all in search for legal help or advice. I had a troublesome case, it had me very worried and distraught, I had no idea what to do. I talked with Jeff in a FREE consultation, he was very knowledgeable and understanding of my situation, it had made me feel a lot more comfortable about my case and the position I was in (as if I was family). Every time there was something new about my case or even if I had questions, I felt comforted and relieved, Jeff responded very quickly.

I know not every case is the same and may not be dismissed like mine was, but with Wolf Law in your corner, I believe you have a fighting chance. Thank you again Wolf Law for fighting with me!

So Glad I Hired Jeff Wolf for My DUI Case

I was originally considering not hiring an attorney since this was my first DUI offense but I’m definitely glad I did. It was my first DUI but I was involved in a one-car accident and totaled my car. I started to worry about the possible consequences after reading the penalties online. I contacted Jeff’s office after reading reviews on AVVO left by other clients. From the beginning he was very straightforward regarding possible penalties and possible outcomes, and gave me the details of what he would do if I hired him.

We worked out what strategies we would use for the DMV and Court. Without going into too much detail, I have to say that I was extremely happy that I decided to hire Jeff. Immediately after hiring him I felt a lot less stress about the whole situation. He was always in contact with me every step of the process and even did things for me that I didn’t have to do myself, like my DMV hearing.

Every DUI case is different based on many different circumstances, so I can’t say that my results will be yours, however I was extremely happy with my results. He won my DMV hearing, and I didn’t lose my license and got pretty much the minimum penalties in court. Overall, I would recommend him to any family or friends who find themselves in the same situation. I have several friends who had similar situations who couldn’t believe how lucky I was to get the outcome that I did. Thank you for everything Jeff!

Fantastic Attorney, Thorough and Knowledgeable

When I had charges pending against me, I had a free consultation with many attorneys and ultimately hired Jeff wolf as my formal representation. Most of the attorneys’ capabilities were relatively equal, but what stuck out with Jeff was his ethics and personal investment in my outcome.

From the beginning he tried to get a thorough sense of who I was in society and represent that to the judge for sentencing. In court he pleaded my case and balanced remorse for the action with any positive attributes to gain a favorable outcome. He is well spoken and respected in court.

I liked that his payment model worked through stages that he “earned” along the way. I had a clear understanding of what to expect from him, from the court, and the most likely requirements of my sentence. And when I didn’t understand or had additional questions on one part (and I had many) he took the time to explain and discuss the options and his recommendation with me.

He had a thorough knowledge of the system and its players as well as knowledge on unusual factors related to my specific case, and he made well-thought-out recommendations with reasoning but ultimately let me make the final decision.

The result of my case was quite favorable thanks to Jeff. Great lawyer, highly recommend.

DUI Charge Reduced to Reckless Driving

I approached Mr. Wolf due to a first-time DUI charge. He was extremely knowledgeable and professional throughout every step of the legal process. As a result of his diligence in court, the charges against me were reduced to reckless driving. I would recommend Mr. Wolf’s services to my friends and family.

Wolf Law Saved My Career

I’m a college student in a highly prestigious nursing school. After a night of drinking, my now ex-girlfriend and I got into a heated argument that landed me with domestic violence charges. I thought my career was over and the tens of thousands of dollars I spent on multiple years of school were all for nothing. However, Mr. Wolf was able to get two of my three charges dismissed altogether (one of them being the most serious) without us even walking into the courtroom. When we got to court, he was able to get me a deferred sentence–the best possible scenario. All in all, Wolf Law is hands-down the best in the Denver area. They are the reason I can still pursue my career goals.
