How Long Does CBD Stay in Your System? A Comprehensive Look

Cannabinoid (CBD) is a non-intoxicating substance in the cannabis sativa plant believed to moderate anxiety and minor pain. It is mainly grown purposely to act as a supplement. CBD is found in the body's fat tissues since it is fat-soluble. Like any other drug, CBD undergoes processing in the body. CBD may have some time in an individual’s system ranging from hours to approximately a month. It can stay in the body for 2 to 5 hours. However, this range does not apply to everyone.   In some individuals, it may last for weeks, depending on various factors. This article explains how long CBD stays in an individual’s system comprehensively.

The half-life of CBD in the body ranges from one hour to about five days. Half-life in medicine means; the period the body takes in removing one-half of a drug when it is compared to its original amount. The body can eliminate a drug in about four to five half-lives. Therefore, several factors should be considered by any CBD user before using it. For example, the half-lives of CBD drops and sprays are 1.4 to 10.9 hours. Too much consumption of CBD products orally raises its half-life to 2 to 5 days. However, someone who smokes it as required has a half-life of 31 hours. It shows that CBD sprays may last longer in the body, about 10 hours to at most two days. For individuals who are smoking CBD in massive amounts, it can stay in the body for almost ten to25 days. The approximated CBD half-life is two to five days, mainly for people with CBD dosed orally. There is a variation in the rest of the delivery methods.

Factors Determining CBD Retention in the Body

Usage Frequency. Several factors considered to look at and influence the duration that CBD lasts in the body are explained. Since the time it takes and the period an individual detects it is usually not the same for everyone, it is, therefore, the defendant on the following:

The frequency of using CBD will influence the total time it will take to remain in the body. Regular usage of CBD increases in the body as an individual is still using it. According to  Goldstein (2016), taking CBD should be at least one week to prove it is suitable for you. Using it rarely clears itself from the system.


Backer et al. (2019) explained that taking large amounts of CBD at a given time influences the duration the cannabinoid lasts in the system. It means that the big the dose an individual takes, the period of CBD in the body also increases.

CBD Administration Methods

CBD effects and its presences in the body determine how it may impact the body. CBD can be in the form of edibles, vaping, creams, lotion, oils, and tinctures, or pills and capsules. According to Bridgeman & Abazia (2017), a person's method of taking CBD impacts the onset and duration of effects and the general period it may last in the body system. For instance, if a person vapes or smokes CBD, their plan takes its impact at least immediately, unlike ingesting, which can last up to one hour or two.

According to Bickel et al. (2019), when vaping CBD, it enters the lungs, and its effects are felt quickly and come out so fast. Absorption of tinctures and oil placed under the tongue takes very fast, and they stay in the bloodstream for a long time. The digestive system performing edible metabolic forms of CBD usually takes a while. Oils and creams also last for quite a long period in the body, taking longer to come out. The method of consumption is key to determining the duration CBD will last, and the time one will begin feeling its effects. Inhalation of CBD reached the blood in 3 minutes. It shows that its products are immediately felt after consumption. The duration lasts in the body system is five minutes to some hours.

Food and Activity

CBD on an empty stomach tends to be processed faster in the body when compared to on a full stomach. Likewise, for individuals who regularly exercise, there are cannabinoids such as THC and CBD metabolism takes less time. Many people with the ‘’runner’s high’’ have experienced a feeling of vision during cannabis usage and exercise. The feelings result from the release of cannabinoids that store fat during activities.


Since several factors must be considered, it is not easy to tell the duration CBD lasts in an individual’s system. Also, our bodies are quite different, resulting in different responses toward CBD. The method used, dosage, and body composition are vital in making it hard for an individual to guess the rate of CBD kicking in and how it will affect an individual. A small dosage of CBD and a slow increment as one approaches the body's desire are recommended. The dosage measure of CBD is determined by several factors, such as the weight of the body, the chemistry of the body, the CBD concentration on the product being used, and finally, the treated condition. In terms of body weight, the body mass index (BMI) plays a crucial role in determining how faster is metabolized. The bigger the body weight results in a longer duration to last in the body system. Whichever condition an individual is making an effort to treat using CBD, a considerate dosage that you apply to yourself should be paramount. If not so, CBD may not be the right choice for you. Like any other drug, CBD requires restrictions. After taking it, CBD is processed by the body, and the duration it may last in the body might be longer depending on the few factors illustrated above. Other CBD may stay in the system for even weeks. So it is necessary to look at the many determinants before consuming CBD, and the amount of dose one is likely to take. It is also important to note that FDA regulates not all CBD products; therefore, the CBD a person may be consuming can be a mixture of other cannabinoids that may take a little bit longer to detect CBD. Also, the more regular you take products from cannabis, the increases the detectability chances.
