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.

Incredible Representation

I cant say enough positive things about my experience with Jeff Wolf. This was my first time needing a lawyer for representation, and Jeff made me feel informed and secure throughout the whole process. I couldn’t have asked for a better person on my side. He was able to navigate me thru a stressful time and it meant the world to me. He was great with DA; calm, but firm and determined to get me the best possible result. Also, the presiding judge clearly thought highly of Jeff Wolf. I would highly recommend Jeff Wolf to anyone looking for legal representation.

Jeff Wolf was Well Worth the Investment

When you get charged with a crime it is tough to deal with, mostly because you are embarrassed and disappointed with yourself for what you have done. I was charged with theft and was very worried about what type of impact that would have on my business professional career when applying for jobs. I contacted a few lawyers but knew that Jeff was the right direction to take. He made me feel more at ease knowing that people make mistakes and that this would not effect my whole life. He was very helpful and quick to respond to any questions or concerns that I had.

During my time with Jeff he made me feel very comfortable and I knew going into everything what to expect, what to say, and how to present myself. Whether you hire a lawyer or not is your own decision. But to me what Jeff was able to provide was well worth it. I literally told him my story, how I felt and what type of outcome I was looking for on the first day. Besides showing up with him to court he did everything else and took care of everything. We were sentenced to the verdict that we were looking for and now I can move forward and put this case behind me. Thanks for all your help Jeff it was much appreciated.

My Heart Was Ripped Out, Wolf Law Showed Compassion

In early March, my heart was seemingly ripped out. I was driving into town with my two children, 5 and 2, in extremely inclimate weather conditions when my car hit a patch of ice and I lost control of my vehicle. It was a horrific accident and I was the only survivor in my vehicle. As if this wasn’t the worst thing that could have ever happened, I was charged with careless driving resulting in death, two counts. I was referred to Mr. Wolf by four separate law offices, as well as the BAR Association. The District Attorney’s office attempted to raise my charges to much more serious felony charges that could have carried very harsh sentences. Mr. Wolf was able to maintain the original charges and speak compassion and mercy to the the judge, leaving me facing only community service and a short probation with minimal associated probation costs. I would recommend his services to anybody and everybody. Not only is he incredibly knowledgeable, but he is passionate about his work, while showing the utmost compassion and respect for his clients’ situation.

Wolf Law is your best option!

I’ve had the privilege of getting Jeff Wolf to represent me in my 1st DUI case. He did a great job explaining the case, the possible outcomes and overall getting good results. I highly recommend his services to anyone who has any moving violation infraction perhaps more and want to have the best results in court. Thank you Jeff.

Wow

Unfortunately, I have required an attorney more than a few times. That said, Jeff is the most intelligent, competent, compassionate, committed, aggressive representation to be found, without a doubt. Facing a felony DUI, no proof of insurance, careless driving and cruelty to animals (my dog gets more love than most people in the world), followed by two DURs (driving under revocation), I pretty much felt I was screwed. After hiring and firing two attorneys, I called Jeff. Note: Do your research before you waste money, and do whatever it takes to get the money for proper representation. I met with Jeff based on his peer reviews, client reviews, education and experience; all of them positive and 100 percent accurate. Twenty minutes into the consultation, all my built-up stress and anxiety had been significantly reduced. I thought my driving privileges were over for a while. Jeff showed me what I needed to do to get a restricted license, which I was able to do within a few days. Following that he made two DURs, jail time offenses, turn into one zero-point traffic violation. Then, one year to the date of my run-in with the law, Jeff and I went to trial. The no insurance charge was dropped. I was insured. The cruelty to animals charge was dropped after the first day of trial. On the second day, I was found not guilty of DUI, DWAI and careless driving. The time, effort and determination Jeff put in was clear, and his strategies and trial skills were clearly superb. No better counsel can be found in my opinion.

Kind, Knowledgeable, and No-Nonsense Attorney

I hired Mr. Wolf to represent me in my efforts to obtain a permanent civil protection order against the person who committed a crime against me. This person is currently incarcerated for the crime but is being considered for parole. Due to Mr. Wolf’s criminal law background, and his outstanding attorney ratings, I believed him to be the best legal professional to successfully represent my safety and security concerns in court. I was not wrong!!

Mr. Wolf expertly and succinctly prepared the protection order paperwork on my behalf, prepared me for my court appearance in a direct and as complete a manner as possible, and successfully represented me in court. He also expressed sincere kindness towards me from the day I hired him to the conclusion of my case. Another attorney without a criminal law background may have been able to have successfully obtained a permanent civil protection order on my behalf; however, I was unwilling to take that chance given the criminal background of my case. I will be forever grateful to Mr. Wolf for his successful representation of me, and for making my safety and security one of his top priorities.

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.

Best in the business

Working with Mr. Wolf was an absolute privilege. Having never been in trouble with the law before, Jeff was there for me each step of the way from the day before I turned myself in, to the very end of my case, which he was able to help me get dismissed.

A true professional, he was nothing but honest and fair to me. He showed me and my family the utmost respect through a difficult time. At a point when I felt alone, Jeff was there to make sure I would be ok.

He is true to his word, and each step of the way, he and his team will keep you informed on any and all items that need to be addressed.

Because of Mr. Wolf, I can continue with my life and move forward. Thank you, Jeff Wolf, and everyone at the firm. If anyone I know ever needs a defense attorney, I will recommend the best in Colorado. Wolf Law.

The best lawyer you could ever hire !!!

Jeffrey Wolf is the best lawyer you could ever hire. He most definitely went way above and beyond the call of duty for me and my case. I’m sure that some of you have hired other lawyers in the past and it seemed like they drug their heels, and wouldn’t return calls, which made you feel that they didn’t care about you.

As far as I’m concerned that will never happen to you if you hire Jeffrey Wolf. He treated me like I was either his best friend or a member of his family, that’s how I felt dealing with him. I honestly looked forward to his calls. He seems like a super cool/good guy. If I lived in Colorado I would be honored to even hang out sometime, maybe shoot some pool, go bowling, ect just have fun. But the most important thing as far as business goes he got an amazing result for me in the case he represented me for. If yall don’t hire Jeffrey as your attorney then you’re making a HUGE mistake that you will probably regret the rest of your life. Again tyvvvvvvvm Jeffrey Wolf for taking care of me. You are the best.
