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.

Great Attorney

I contacted Mr. Wolf through a reference from a separate out-of-county attorney’s office. I was very pleased with his professional attitude and staff, but mostly the results he was able to achieve for my case. I would definitely recommend Jeff and hire him again if I ever need to.

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.
