Can You Smoke or Vape CBD and Drive in California?

Cannabidiol, more commonly known as CBD, has become a mainstream wellness product in California and across the United States. Praised for its potential health benefits, such as pain relief and anxiety reduction, without the intoxicating “high” of THC, CBD is widely available in various forms. However, as a compound derived from the cannabis plant, its relationship with driving laws can be complex and confusing. Can you smoke or vape CBD and drive in California? Can you be charged with a DUI for having CBD in your system? This guide delves into California’s specific laws regarding CBD, driving under the influence (DUI), and what you need to know to stay safe and legal on the road.

The Legal Status of CBD in California

California has long been a pioneer in cannabis legalization, being the first state to legalize medical cannabis in 1996 and later recreational use. The state’s laws have evolved to specifically address hemp-derived products like CBD.

The Federal 2018 Farm Bill: This landmark legislation federally legalized the production and sale of industrial hemp, defined as cannabis containing less than 0.3% delta-9 THC by dry weight. This made hemp-derived CBD products legal at the federal level.
California Assembly Bill 45 (2021): This state law officially legalized the manufacture and sale of consumable hemp-derived products in California, including CBD-infused foods, beverages, and supplements, for adults aged 21 and over.

This legal framework means that compliant, hemp-derived CBD products are legal to purchase and possess in California. However, their use in the context of driving is subject to a different set of rules.

The Core Issue: DUI Laws and CBD Consumption

The laws surrounding driving under the influence of CBD are complicated. While California law does not set a specific legal limit for the amount of CBD in a driver’s bloodstream, the act of consuming CBD products while operating a vehicle is strictly regulated.

Is It Illegal to Smoke or Vape CBD While Driving?

Yes. California law is clear on this point: it is illegal for a driver or a passenger to smoke or ingest any cannabis product, which includes hemp-derived CBD, while in a moving vehicle. This prohibition is outlined in the California Vehicle Code and treats the consumption of cannabis products in a car similarly to the consumption of alcohol.

This ban applies to all forms of consumption, including:

Smoking or vaping CBD flower or concentrates.
Ingesting CBD edibles, such as gummies, brownies, or beverages.

Sgt. Oscar Chavez of the California Highway Patrol has noted that while it might be difficult for an officer to distinguish between a tobacco cigarette and a CBD cigarette, or a normal brownie and a CBD-infused one, the law is explicit. An officer typically cannot stop a vehicle solely on the suspicion of CBD or marijuana consumption. However, if a driver is pulled over for another traffic violation (like speeding or swerving), and evidence of recent consumption is found, a citation can be issued.

Open Container Laws for CBD and Cannabis

California law also provides specific rules for the storage and transportation of cannabis products (including CBD) in a vehicle, which are similar to the state’s open container laws for alcohol. To be transported legally:

The cannabis or CBD product must be in a sealed container.
If the container has been opened or the seal is broken, it must be stored in the trunk of the vehicle, where it is not accessible to the driver or passengers.

Driving with an open container of a cannabis or CBD product in the passenger compartment of your vehicle is a violation.

Can You Get a DUI for Driving After Consuming CBD?

This is where the legal situation becomes more nuanced. While consuming CBD in a moving vehicle is illegal, the question of a DUI is typically tied to impairment.

Pure CBD is non-psychoactive and generally does not cause the cognitive and motor impairment associated with THC. Most studies suggest that CBD alone, even in high doses, has little to no effect on driving ability. Therefore, getting a DUI for being “impaired” by CBD alone is highly unlikely.

However, there are several critical caveats:

Presence of THC in CBD Products: Full-spectrum CBD products, by law, can contain up to 0.3% THC. While this is a small amount, regular or high-dose use could potentially lead to the presence of detectable levels of THC in your system. California does not have a “per se” nanogram limit for THC in the blood for DUI cases (unlike states like Washington or Nevada). Instead, a California DUI charge for drugs is based on proving that the substance has “so far affected the nervous system, brain, or muscles as to impair to an appreciable degree the ability to operate a vehicle in a manner like that of an ordinarily prudent and cautious person in full possession of his faculties.”
Inaccurate Labeling: The CBD market is not always perfectly regulated. Some products may contain more THC than what is stated on the label. If you consume a product with a higher-than-expected THC concentration, you could potentially become impaired and fail a drug test.
Combined Effects: If you consume CBD along with alcohol or other substances, the combined effects could lead to impairment, even if neither substance alone would have been enough.

Law enforcement officers in California are trained as Drug Recognition Experts (DREs) to detect signs of impairment from various substances, including cannabis. If you are pulled over and an officer has reason to believe you are impaired, they can conduct field sobriety tests and may require a blood or urine test. While a drug test can detect THC, it cannot determine the exact time of use or the level of impairment. Therefore, a DUI case would rely on the totality of the evidence, including your driving behavior, physical appearance, and performance on sobriety tests.

Frequently Asked Questions (FAQs)

Is it okay to drive after using 5% CBD Oil?

If you are applying a topical CBD oil to your skin for pain relief, it is highly unlikely to cause any systemic effects or impairment, making it generally safe to drive. However, if you are ingesting a CBD oil tincture, you should be aware of how it affects you personally. If you experience any drowsiness, it is not safe to drive.

Is CBD detected in a police drug test?

Standard police drug tests are designed to detect THC, not CBD. However, if you use a full-spectrum CBD product that contains trace amounts of THC, it is possible for THC or its metabolites to show up on a drug test. This is a significant risk for individuals who must undergo drug testing for employment or other reasons.

Is it okay to smoke or vape CBD in a parked car?

California law prohibits the public consumption of cannabis products. If your car is parked on a public street or in a public parking lot, smoking or vaping CBD would likely be considered a violation. However, if your car is parked on private property (like your own driveway) where you have permission to consume cannabis, the rule may not apply.

Conclusion: Prioritize Safety and Abide by Consumption Laws

In summary, while the purchase and possession of compliant, hemp-derived CBD products are legal for adults in California, their use in the context of driving is strictly regulated. It is illegal for a driver or passenger to consume any CBD product (by smoking, vaping, or ingesting edibles) while in a moving vehicle. Furthermore, all open containers of cannabis or CBD products must be stored in the trunk.

While getting a DUI for being impaired by CBD alone is highly improbable, the presence of trace amounts of THC in some products and the potential for side effects like drowsiness mean that users should exercise extreme caution. The safest and most legally sound approach is to never consume any CBD product while driving and to be fully aware of how any CBD product affects you before you get behind the wheel. Always prioritize road safety for yourself, your passengers, and everyone else sharing California’s roads.
