The length of time that 500mg of CBD stays in your system depends on a variety of factors, including the dose taken, the frequency of use, and the method of consumption. The half-life of CBD in the body can range from about 1 hour to up to 5 days. It usually takes 5.5 half-lives for a drug to be completely eliminated from the system, meaning that CBD taken orally would completely leave the body in about 11 to 28 days. However, it may take longer for a regular user to completely remove CBD from their system than an occasional or new user.
The metabolites of CBD can usually appear in a urinalysis between three days and two weeks after the last time they were taken. Inhalation is an effective method of administering CBD because of its rapid absorption and the effectiveness of the lungs in transferring CBD to the bloodstream. The half-life of vaporized or smoked CBD in blood plasma is much shorter than that of CBD ingested within a few hours. Most experts suggest taking CBD for at least two weeks to see how it affects your health and if you're reaping the benefits or not.
Drug tests don't look for CBD, so if you take normal doses of full-spectrum CBD oil, you're clear about that. Even if your THC test result is false, you can tell your employer that you're taking full spectrum CBD oil and request another screening test. The type of pharmacological test given to you, and the time elapsed since you last took CBD, could influence whether it is detectable. It is important to note that accurate information on how long CBD stays in the body remains limited compared to information on THC.
Therefore, it may be impossible to detect it in a blood test much earlier than 11 to 28 days after ingestion.
