Die Wirkung von CBD

How long does CBD stay in the body and can I drive after consuming CBD oil?

Cannabidiol, more commonly known as CBD, has emerged as a major player in the world of natural health in recent years. Derived from the hemp plant, CBD is known for its therapeutic benefits without the psychoactive effects of its cousin THC. An important question that many users of CBD products ask is: "How long will CBD stay in my body?" This article provides a comprehensive answer to this question.

What is CBD and how does it work? CBD is one of over a hundred compounds found in the cannabis plant. It interacts with the body's endocannabinoid system, which plays a role in a variety of processes such as pain, mood and sleep. Unlike THC, CBD does not cause a “high,” making it an attractive option for those seeking relief without psychoactive effects.

Factors that affect how long CBD is in the body

The length of time CBD stays in the body depends on several factors:

  • Dosage and Frequency The higher the dose and the more frequently CBD is consumed, the longer it stays in the system.
  • Metabolism – People with faster metabolisms process CBD faster.
  • Body type - Body weight and body fat percentage can affect duration as CBD can store in fat cells.
  • Method of Ingestion - The method of ingestion (e.g. oils, capsules, topicals) influences how quickly CBD is absorbed and how long it remains in the body.
  • And other physiological factors influence absorption and excretion rates. Regular users take longer to completely eliminate CBD, while occasional users clear CBD more quickly from the body.

Different forms of consumption and their effects

Oral: CBD oil, capsules or edibles have a half-life of 2 to 3 hours, with effects occurring more slowly but lasting several hours.

Sublingual: Absorption under the tongue allows for a rapid onset of action within a few minutes with a half-life of 1 to 10 hours.

Inhalation: Inhaling CBD flowers has a short half-life of 1 to 2 hours, resulting in a quick but shorter effect.

Use on the skin: CBD creams remain local and are slowly absorbed through the skin, with a noticeable effect after 30 to 45 minutes and complete elimination after a few hours.

How long does CBD work in the body?

The length of time CBD stays in the body is an important consideration for anyone experimenting with or consuming this cannabinoid on a regular basis. The length of CBD in the body varies depending on consumption and depends on various factors such as the amount of CBD content, the method of administration, body weight and the individual metabolism. CBD is available in various products, including smoking flowers, CBD capsules, CBD oil, CBD gel, drinking water, sweets and personal care products, which vary in their effects and speed of absorption.

Scientific studies give average values ​​for the elimination time of CBD between 18 and 120 hours, depending on various factors. However, the studies emphasize individual differences and the need to take these into account.

CBD vs. THC: Differences in excretion

CBD has a longer elimination time than THC. This is because CBD tends to be stored in fatty tissue. THC is metabolized more quickly and can be detected in metabolites over a longer period of time.

Driving in Germany with CBD

CBD is a legal and freely available herbal product in Germany that does not fall under the Narcotics Act. Since CBD does not intoxicate and the THC content in reputable products is less than 0.2%, it usually has no influence on the ability to drive. Police drug tests are not focused on CBD, but on THC. Nevertheless, it is not recommended to carry CBD flowers in the car to avoid confusion.

How long can CBD be detected in the body?

CBD is usually not detectable for long in urine and blood tests. The concentration of CBD in urine depends on the frequency of consumption and can be detectable for up to two hours after a single consumption. CBD can only be detected in the blood for a few hours.

CBD and road traffic: Driving with CBD oil?

Not only the consumption of substances, but also the taking of medications can impair your ability to drive. It is advisable to leave the car if you experience disorientation, sensory impairment, problems pedaling or insecurity, whether due to illness, medication, CBD or other reasons.

Can you drive a car while consuming CBD? - In summary, CBD does not generally have any negative effects on driving ability as long as it is consumed responsibly and legally. Nevertheless, it is important to be aware of your own reactions and, if in doubt, to use alternative means of transport.

CBD interactions with medicines and individual advice

It is important to note that CBD can interact with other medications, which can affect elimination time. Therefore, consult your doctor to ensure that taking CBD is compatible with your medications.

Tips for using CBD safely

To use CBD safely and effectively, you should start with a low dose and slowly increase it until you achieve the desired effects. It is also important to choose high-quality products from trusted manufacturers.


The length of time CBD stays in the body varies depending on several factors, including method of ingestion, dosage, frequency of use, and individual physical characteristics. While CBD is a useful therapeutic agent for many people, it is important to be aware of its potential drug testing effects and the best method of use. With the right approach, CBD can be a valuable addition to your wellness regime.
