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.

Fully and Enthusiastically Recommended

When I was arrested for DUI/careless driving, I was overcome with a profound sense of hopelessness – I couldn’t eat, I couldn’t sleep, and I thought my life (including my career) was ruined. Making the decision to call Mr. Wolf for a consultation was the best decision I could have made. His immediate response set my mind at ease and gave me a the peace of mind that I so desperately needed.

Upon meeting him in person, I was thoroughly impressed by his experience and expertise, but what really struck me was his personable demeanor and genuine interest in helping me. He was very patient in explaining the legal process and made sure I was well prepared for every step of the way.

There is no doubt that his representation and advocacy, as well as the advice he had given me in order to prepare for court, resulted in an outcome that was more positive than I had dared hoped for (a DWAI with license intact and a reduced probation sentence), allowing me to move forward with my life. Mr. Wolf far exceeded my expectations, and I would absolutely recommend him to anyone seeking legal counsel.

Jeff Wolf Helped Me Keep My Job

Jeff was a terrific advocate while representing me through my DWAI. He was professional. I am convinced that it was his prior trial experience and effective communication skills that secured a much more desirable sentence than I had expected. I am positive that Jeff’s representation made it so that I could keep my job.

Best Possible Outcome Thanks to Wolf Law

When I walked into the office I was at a low point I can’t describe. When I talked to Jeffrey Wolf I wanted to hear, “Don’t worry, you’re going to be fine.” Instead I was told the honest truth: I was in serious trouble, but he would fight like crazy to get me the best possible outcome. After thinking about that I realized it was far better to hear the truth rather than a lawyer trying to get my business, and in the end I got exactly what Jeff said: Good advice, an excellent professional defense, and I believe the best possible outcome I could have wanted. I highly recommend Wolf Law.

Informative, Kind, Helpful: Can’t Thank Him Enough

My experience with Wolf Law was excellent. I am a full time college student and Mr. Wolf was beyond helpful to me, and provided me with all of the information I needed. He is very kind and always available for questions and support. I can’t thank him enough for all of his hard work.

My Son Was in Trouble, Jeff Wolf was His Advocate

When my son got in trouble, I was referred to Jeff Wolf by a friend. He was immediately responsive, calling me back within an hour. We set up a meeting for a couple of days later with no obligation, and when we met he helped us understand the many aspects of my son’s case. We retained him and were grateful for his obvious comfort with the legal system and ability to help us navigate it. Throughout, he advocated for my son but also was stern with him, very clearly communicating the severity of his situation. We ended up with a deferred sentence and are so glad we had Mr. Wolf’s help. He is very reliable and accessible; it was reassuring to know we had him in our court.

Outstanding Law Firm

Wolf Law was very helpful in fulfilling my personal needs. Colleen Kelley knew how to approach my case and made me feel better about my results in the bargain. I would recommend her to anyone with criminal trouble; she is an amazing lawyer.

Wolf Law is Well Worth the Investment

Thanks to Jeff Wolf I had the ideal outcome on my case, whereas without any representation it would’ve been a less than desirable outcome without me even fully knowing my options. He was extremely informative and thorough; it was clear that not only did he know what to do for every scenario but I was confident that he would make it happen, which he did. Very personable and easy to trust, I highly recommend Jeff and Wolf Law.

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.

Colleen Kelley and Wolf Law

In the past few years I have had the unfortunate circumstance of needing a criminal defense attorney. I cannot overstate how fortunate I was to have chosen Colleen Kelley. I can honestly say that without Colleen on my side that I would have been sentenced to significantly more time and more serious charges than were warranted in my situation.

Colleen is undoubtedly a major reason as to why I am free today and able to move on with rebuilding my life. I would without hesitation recommend Colleen to anyone who needs a criminal defense attorney.
