Colorado has some of the most progressive marijuana laws in the country, allowing both recreational and medical use. However, legal use of marijuana doesn’t mean immunity from DUI charges. Many medical marijuana cardholders believe their legal right to use cannabis protects them from a DUI, but this is not the case. Colorado law strictly prohibits driving under the influence of any substance, including marijuana, regardless of whether you have a medical card. If you’re a medical marijuana user, here’s what you need to know about DUI laws in Colorado and how they may apply to you.
In Colorado, it is illegal to drive while under the influence of marijuana. The state defines a person as being under the influence if their ability to operate a vehicle is "substantially impaired" by the consumption of drugs, alcohol, or both. For marijuana, the law establishes a "permissible inference" that a driver is impaired if they have 5 nanograms or more of THC (the psychoactive compound in marijuana) per milliliter of blood.
It’s important to note that this 5-nanogram limit is not a strict threshold. Even if your THC level is below this limit, law enforcement can still charge you with a DUI if they believe your driving was impaired by marijuana use. Conversely, drivers with a medical marijuana card are not exempt from these laws. Whether your use is recreational or medicinal, the rules regarding impaired driving apply equally to all Colorado drivers.
Yes, having a medical marijuana card does not protect you from being charged with a marijuana DUI. Colorado law does not differentiate between medical and recreational marijuana when it comes to impaired driving. Even if you are using marijuana to treat a legitimate medical condition, driving while under the influence can still result in a DUI charge.
Additionally, medical marijuana cardholders may face heightened scrutiny during a traffic stop if law enforcement discovers they are using cannabis. Officers may administer field sobriety tests or request a blood test to determine THC levels. If your THC levels are above the permissible inference limit of 5 nanograms or if your driving behavior suggests impairment, you could be charged with a marijuana DUI.
Determining marijuana impairment is more complicated than alcohol-related DUIs. Unlike alcohol, which has clear correlations between blood alcohol content (BAC) and impairment, THC affects individuals differently. Factors such as frequency of use, tolerance levels, and how recently you consumed marijuana can all influence the presence of THC in your system without necessarily indicating impairment.
Law enforcement officers in Colorado rely on several methods to assess impairment, including:
Because these methods are not foolproof, it’s crucial to consult with an experienced DUI attorney if you’re charged with a marijuana DUI, especially as a medical marijuana cardholder.
The penalties for a marijuana DUI in Colorado are the same as those for an alcohol-related DUI. They include:
In addition to these penalties, a marijuana DUI conviction will appear on your criminal record, potentially impacting your employment opportunities, insurance rates, and more. For medical marijuana users, a conviction may also raise questions about your ability to manage your condition responsibly.
