CBD usually stays in the body for 2-5 days, but this interval does not apply to everyone. For some, CBD can stay in their system for weeks. THC is usually only detectable in plasma for about five hours after taking it. However, THC metabolites and thus CBD can be present for up to a week. In a 2005 randomised, double-blind, controlled study published in Therapeutic Drug Monitoring, volunteers were given cannabis extract with 2.The research team found that CBD was only detectable in the blood for up to nine hours after ingestion.
Therefore, CBD taken orally would leave the body completely in about 11-28 days, but could be undetectable in a blood test much earlier. The half-life of inhaled or smoked CBD in blood plasma is much shorter than that of ingested CBD, only a few hours. A regular user may take longer to completely eliminate CBD from their system than a casual or new user. There are several factors that can contribute to how long CBD stays in the body, such as body weight and metabolism, diet, dosage, how CBD is taken and how often it is taken, and studies have shown that CBD can remain in the body for several days, possibly more than 10 days in some cases. CBD will probably not show up in a drug test, and studies have shown that CBD does not stay in the system for very long.
In some cases of heavy use, CBD can remain in the system for up to a week, with detection windows extending to over a month. Although blood tests are not as common as urine tests for CBD and cannabinoids, they can be used to detect THC metabolites. CBD (or cannabidiol) is stored in the body's fat cells and can theoretically remain detectable for days or even weeks in a blood test. Taking CBD products with unknown amounts of THC would only give a valid result if a lab test was performed on a blood sample within this short period of time. You can get CBD isolate in oil form, as cbd oil pain cream, and in any other form you can get other CBD products.
It is a common misconception that CBD and THC are the same; although CBD is a natural supplement, it is still possible for THC metabolites to be detected during drug testing.
