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 can take longer to completely eliminate CBD from their system than a casual or new user. The time it takes for CBD to take effect, as well as the duration of the effects, will be different. As a general rule, the effects of CBD last between 2 and 8 hours. 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. In the case of single exposures, THC and its metabolites are detectable in urine for about 3 days after the last intake. While CBD can remain in our systems for up to 3-4 days, on average, it is gone in a couple of days.
You will experience the effects of CBD for approximately 2-6 hours if you ingest it orally. If you apply it topically, you can expect the impact to last around 6 hours and be incredibly localised. Cannabidiol can build up in the body over time with regular use, so using CBD often will also slow down your body's processing time, and leave it in your system for longer. On the other hand, CBD canna oils are processed by the body's bloodstream and can stay longer, as can CBD topicals, which also tend to have a longer shelf life. If you are new to CBD and wondering how long its effects last, you will need to give your body some time to adjust to its consumption. Higher doses of CBD can also have an effect on how long the CBD will stay in the body, unlike smaller doses.
A single dose of CBD can continue to work for several hours, and the cannabinoid can persist in the body for days or weeks. 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. For example, when vaping CBD the effects are felt quickly, it is processed quickly, and tends to leave the body more quickly as well. CBD topicals are excellent at providing localised benefits to the area of the body where they are applied. On average, however, you should expect CBD to remain in your body for a couple of days, but not much longer. That said, on average, users can expect to see CBD leave their body for a couple of days at most.
Still, the general premise is the same: taking significant amounts of CBD will cause it to stay in the body for longer.
