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. Therefore, CBD taken orally would leave the body completely in about 11-28 days, but it may be impossible to detect it 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 an occasional or new user. Depending on dosage, frequency of use and metabolism, you can expect CBD to be completely eliminated from your system in 2-5 days. Frequent or high doses naturally take longer. Without a lot of hard data to rely on, you may want to play it safe before taking a drug test and assume that CBD leaves your body at the same rate as THC. According to the Mayo Clinic, a urine test (the most common type used for workplace testing) can detect THC metabolites for 10-15 days in the case of daily use. Depending on the portion and frequency of use, the figures may vary.
CBD is a cannabinoid that will spend some time in your body once you have consumed it. There are several factors that can contribute to how long CBD stays in your system, such as your body weight and metabolism, your diet, dosage, how you take CBD and how often you take it, and studies have shown that CBD can stay in the system 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. Flannery told us that a person's body weight does not really alter how long CBD will stay in the system. Most topical products stay on the skin and muscles without entering the bloodstream, which means that CBD (and any THC it contains) won't be in your system at all.
Although the type of CBD product you use influences how long it will stay in your system, the dosage plays a more important role. It depends on the amount and frequency of dosing, the form of CBD and, perhaps most importantly, whether you use CBD isolate, broad-spectrum CBD oil or full-spectrum CBD oil. You can get CBD isolate in oil form, as cbd oil cream for pain, and in any other form you can get other CBD products. The highest bioavailability (the amount that is absorbed and reaches the bloodstream) comes from CBD that is vaped or smoked, with CBD oil tinctures applied sublingually (under the tongue) coming in second place. If you are concerned about any occupational consequences of CBD oil use, it may be helpful to discuss the issue with a human resources representative or consult your state's specific CBD laws. When hemp products were legalised in the United States, the law stated that CBD oil and other CBD products could not contain more than 0.
