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.

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.

Grateful for Wolf Law

I had misdemeanor from when I was 19 years old that was keeping me from just renting an apartment because of its classification. I contacted Wolf law to get assistance with seal this 17-year-old case so I could secure an apt without fear of rejection. I was put in touch with Cassandra very promptly. She advised me and told me that I would have to seal the record in order to just have peace of mind as there is no statute of limitations on my situation. She explained the process very thoroughly and answered any questions I had. She was very kind during the whole process which ended up taking some time to get it taken care of. She kept me informed every step of the way. She kept great care to send me documents by mail and email. Cassandra was just fantastic to work with and I am so grateful to have closure from a mistake I was a young adult. If I every need a lawyer again (hopefully not of course) I would definitely contact Wolf law again for help. Thank you so much for helping me!

— Sasha

Amazing Service and Representation

I had the pleasure of working with Cassandra on a petition I was making to the court. Cassandra’s representation was amazing. She communicated exactly what would be required of me. She set realistic expectations of how the process would work and kept me updated on where my petition was i the judicial process. I give Cassandra Monahan and Wolf Law my highest recommendation if you need someone on your side in the judicial system.

Thank you Cassandra for everything you did. I appreciate you!!!

Hire A Lawyer You Can Relate To and Trust

I happened to find Jeff through a Google search for a DUI lawyer and I would have to say I really lucked out. I had heard horror stories about attorneys that overcharged their clients and that they would send others to represent them in court. From the initial phone call he helped me understand the process and prepared me for what was ahead. Having never needed a lawyer he was patient and made sure I understood everything before making any decisions. Jeff always made me feel like I was on the same level as him which I really appreciated. Jeff always prepared me for the worst, but in the end with his hard work and suggestions beforehand he managed to get me a pretty good deal. The best advice I could give is to be informed and START EVERYTHING right away. I would also say to hire a lawyer that you can relate to and that you trust. Don’t waste your money on someone that isn’t going to give you the personal attention you deserve. I would gladly recommend Jeff Wolf! He is down to earth and I never felt judged. He gave it to me straight and without hiring him I don’t know where I’d be. Thanks Jeff!

Sex offender deregistration

Colleen Kelly and her team, supported me and guided me through the process of getting off the registration . I had attempted over the years to do this on my own and at one point hired another attorney to assist me. These efforts were futile, I ended up with unnecessary years ( decades ) of suffering financially, humiliating encounters with personal relationships, landlords, employers, churches and other organizations.
Colleen and team were very professional and knew the steps that I needed to go through to get the job done. I would highly recommend Wolf Law, for their professionalism and caring.
