    How Long Does CBD Stay in Your System?

    The effects of CBD last in the system for around ten to forty-eight hours, depending on various factors such as body weight and metabolism. Regarding expiration, CBD oil lasts for around one to two years. This guide highlights how long CBD oil lasts, including factors that influence how long CBD oil lasts in the system, factors that influence CBD’s oil shelf life and how to extend CBD’s oil shelf life.

    CBD, also known as cannabidiol, is one of the chemical compounds existing naturally in the cannabis plant. The cannabis plant has two sub types, marijuana and hemp. CBD is mostly derived from the hemp plant because of its low concentration in tetrahydrocannabinol. Unlike its famous causing THC, CBD is non-psychotropic. Cannabidiol has various benefits, such as; relieving pain and inflammation, alleviating anxiety and stress and curbing cancer-related symptoms.The cannabis industry is flooded with products ranging from CBD-infused oils, vapes, edibles and topicals. CBD oil is the most popular form of CBD. It comes with a dropper that makes measuring the required dosage easy.

    How Long Does CBD Oil Last?

    Everyone has a unique body chemistry. As a result, there is no standard dosage. Various factors affect how long CBD oil lasts in the system, such as dosage, body weight, metabolism, and frequency of use.

    However, CBD oil generally lasts for around ten to forty-eight hours. CBD's half-life ranges between one hour to five days. Half-life refers to the period taken by the body to excrete one-half of the product. Normally, the body excretes a medication within 4-5 half-lives.CBD oil drops half-life is around 1.4 to 10.9 hours. Consuming CBD sublingually increases its half-life to around two to five days. CBD oil stays in the system for approximately ten to forty-eight hours.

    Factors Affecting How Long CBD Oil Last

    Below are variables that influence how long CBD oil lasts in the system:


    Like other medications, the higher the dosage consumed, the longer CBD oil effects last.

    Frequency of Use

    Fischer et al. (2021) stated that how frequently an individual consumes CBD oil significantly influences how long the effects last. When used regularly, cannabidiol builds up in the body over time. Hence, consuming CBD oil for about a week is recommended to see if it is effective in your body. CBD oil clears from the system if you use it occasionally.

    Your Body

    Everyone has a unique endocannabinoid system and body chemistry. Hence the reason CBD affects every person differently. Body weight, metabolism, and water content affect how long CBD oil lasts.


    The amount of food you eat, the time you eat and what you consume matter. When consumed on a full stomach, CBD effects take longer thanthose on an empty stomach.

    How Long Does CBD Oil Take to Expire?

    Like other substances, cannabidiol oil has a shelf life. CBD oil normally lasts for around one to two years. However, this timeline is influenced by various factors such as CBD type and ingredients used.

    Factors That Affect How Long CBD Oil Last


    CBD oil is manufactured with multiple ingredients such as flavonoids, carrier oil and flavourings.Each ingredient has its shelf life. Flavourings may affect the shelf life of your oil since they degrade faster than cannabidiol.


    Different vendors utilise varying production processes for their oil. It results in varying qualities among them. Reliable companies subject their products to rigorous testing, increasing their shelf life. Authorised vendors receive approval from FSA(foods and standard agency), meaning their goods have better manufacturing standards than unregulated companies. It is best to purchase CBD oil from reputable and trustworthy vendors to be safer.

    The Product’s Quality

    The CBD’s quality also significantly affects the oil’s shelf life. High-quality goods last longer since they are derived from a high-quality hemp plant. The non-organic hemp plant produces short-lasting goods since it was grown in low-quality soil with toxic substances such as pesticides and heavy metals that speed up the product's expiry.

    CBD Type

    There are three types of CBD; full spectrum, broad spectrum and isolate. According to Bilge et al. (2021), full-spectrum CBD contains all compounds and phytochemicals in the hemp plant, including insignificant amounts of THC. De Assis et al. (2021) commented that broad-spectrum CBD oil features all the other compounds and phytochemicals in the hemp plant except THC. CBD isolate contains CBD alone.

    CBD isolate oil lasts longer than broad and full-spectrum since it is purer and contains CBD alone and no other ingredients that could make it degrade quickly.

    Extraction Technique

    There are various extraction techniques used in manufacturing CBD oil. The most recommended one is carbon dioxide since it produces a cleaner and purer shelf life; as result, extending the product's shelf life. Other extraction techniques, like ethanol, shortens the product’s life span. Therefore, before purchasing CBD oil, it is vital to research the extraction technique utilised.


    Where and how you store CBD oil significantly affects its lifespan. Exposing your product to extreme temperatures speeds up its expiry. So, to make it last longer, it is best to store it in a cool and dark place.

    How to Extend the Shelf Life of CBD Oil

    When exposed to various environmental factors, CBD oil’s shelf life degrades. To increase its lifespan, store it in a cool and dark place with a temperature of around twenty-three degrees Celsius. Storing it in a cupboard or pantry significantly helps. Avoid storing it near the window or other heat sources. Additionally, store it in its packaging since the airtight bottleprotects the ingredients against heat and oxygen exposure. Before handling the product, wash your hands thoroughly. After use, seal it tightly. It minimisesits exposure to contaminants such as bacteria.


    Generally, CBD oil lasts in the system for around ten to forty-eight hours. However, this timeline is affected by various factors such as food, body metabolism and body weight. It is made possible by its half-life. A product's half-life is the rate at which the body excretes one-half of the substance. Regarding shelf life, CBD oil lasts for around one to two years. Its shelf life is affected by various factors such as the extraction method utilised, the CBD type, the product’s quality and the vendor. Before purchasing CBD oil, ensure that the vendor is reliable and trustworthy. Once you get it, store it in a cool and dark place to extend its shelf life. A point to note is; before using CBD oil, seek medical guidance on its dosage and side effects.
