CBD and driving: can I get behind the wheel after taking CBD?

CBD (cannabidiol) has become a popular product in recent years due to its many health benefits, especially when it comes to relaxation, better sleep and stress relief. However, many drivers wonder if taking CBD before driving is safe and legal. If you vape or otherwise use CBD, we bring you important information about its impact on driving.

CBD is not THC. What is the difference between the two?

One of the main concerns is whether CBD affects the psyche in a similar way to THC (tetrahydrocannabinol), which is psychoactive and thus the most well-known of the substances in cannabis. However, unlike THC, CBD does not cause intoxication, stupefaction or euphoria. Since May 2021, it has been legally available in certain forms in Slovakia, it is non-addictive and this means that it can be used without fear of an altered state of consciousness.

CBD and reactions behind the wheel

Several studies have looked at the effect of CBD on driving. For example, a Spanish study [1] followed drivers after inhaling 15% or 30% CBD via a vaporizer. The findings showed that participants showed no changes in driving, reaction time or visual abilities. An Australian study [2], in turn, showed that even a high oral dose of CBD (1500 mg) did not affect driving ability or cognition, as confirmed by Swiss researchers [3].

Vaping CBD – the fastest route to effects

Smoking CBD is one of the quickest ways to feel the effects of cannabis itself. There are several ways to smoke CBD, using a conventional cigarette, a so-called joint, or by using an electronic cigarette or vaporizer. Vaping CBD has become a popular form of CBD use, as the effects kick in almost immediately, the exhaled aerosol does not smell, users do not have to worry about coughing, and they can enjoy CBD discreetly, without asking questions or attracting the attention of others. Unlike smoking, and so-called joints, vaporisation does not involve combustion, which means that harmful toxic substances are not introduced into the body, but only what is contained in the herb itself. In addition, inhaled CBD is absorbed into the body up to 3-4 times more efficiently compared to oral consumption. Vaporizers work on the basis of CBD e-liquids (CBD liquids) which often come in a variety of flavors as well, allowing for a better experience and variety of flavors.

Is CBD really safe behind the wheel?

Although most studies show that CBD does not negatively affect driving, each body reacts differently. For some people, CBD can have strong relaxing effects, which could lead to mild drowsiness or slowed reflexes. Therefore, if you experience any side effects after taking CBD, it’s best to avoid driving.

Should I take CBD before driving?

If you are taking quality broad-spectrum CBD products without THC, studies suggest that it shouldn’t affect your ability to drive, and you don’t risk a positive test for THC in your blood either. However, everyone reacts differently, which is why it’s important to try CBD first in a safe environment. If you experience drowsiness or slowed reactions, you may want to avoid the steering wheel.

CBD can be a great tool for relaxation and stress management, but the responsibility behind the wheel always comes first. Even though vape is considered very safe compared to cigarettes, there are still a few risks to watch out for. Although CBD itself is harmless, the other components of e-liquid can irritate the lungs and cause breathing problems. If you want to experience quality and pure CBD, choose products from reliable sources – such as Hemp Farm Liptov.
