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.

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.

True representation

If you are in legal trouble Jeff is the attorney for you!
From the first consultation he was a very understanding and caring guy who tells it like it is. I had a pretty bad charge against me and due to Jeff’s knowledge and his ability to negotiate with the powers that be, he was able to get me a pretty fair deal. He was so kind, putting my mind at ease by telling me I was going to be alright as this was the first time in my life I had ever been in trouble.
In short, if you need a GREAT attorney call Wolf Law and talk to Jeff!

Case Dismissed

I contacted Wolf Law to represent and guide me through legal troubles caused by an unfortunate night of events. I was put in contact with Ms Monahan who was very thorough in explaining the process and was able to file a last minute overseas trip and get court approval for several out of state work trips while the case was still pending. This allowed me to maintain my job responsibilities without awkward conversations or interruptions.

Just months after the incident, Ms Monahan and Wolf Law were able to get the case dismissed and the records sealed. I certainly hope and intend on never needing to call Wolf Law again but if I had to, I would not hesitate to call them again.

Wonderful Experience with Colleen Kelley

I recently had the pleasure of becoming Colleen Kelley’s client. Even despite the terrible circumstances of fighting wrongful criminal charges, Colleen provided a supportive and pleasant experience during this process. Thankfully, I was introduced to Colleen through another attorney. She took my case on short notice and started working on my behalf in less than 24 hours by showing up to court the day after I secured her services.

She was diligent in her research, communication, and pursuit of justice. In just three short months, my case was dismissed. During this three-month nightmare, Colleen provided clarity and assurance along the way. While Colleen was very thorough in regards to every possible outcome I might experience, her professionalism and devotion to this case made it clear that the outcomes would be outstanding from day one. I’m so thankful that I found Colleen to represent me. I would highly recommend her services.

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.

From the beginning Cassandra was honest and gave me confidence and clarity about possible and likely outcomes. She worked closely with prosecution to get me the best outcome available and succeeded in doing so.
