With the rise in popularity of CBD products, many people wonder how long CBD lingers in the body after ingestion. The answer to this question depends on many factors including how much CBD you take and how you take it.
This article explains what the latest scientific research has discovered and answers the question “How long does CBD stay in your system?”.
There isn’t a lot of current research investigating exactly how long CBD stays in your body, but one older study from 1991 showed that CBD levels in the blood were virtually undetectable one week after CBD use was discontinued. The CBD was orally administered to patients with Huntington’s disease over a six week period at 700mg per day, which was a high dose over a long time period. From this clinical trial, it was estimated that the half-life of CBD is two to five days. Half-life means how long it takes something to reduce to half its initial amount.

However, a 2018 review found that other modes of ingestion may impact how long CBD lasts in the body. For example, the review found the average half life of CBD to be:
As you can see, research has shown that the half-life of CBD can vary widely. How long CBD stays in your system depends on how much you take and how you take it.
Additionally, there is very little research on how long it takes the body to completely clear CBD from the blood. Although — based on the available data — it’s likely that CBD will be cleared from your system in about a week, more studies are needed before this question can be answered with confidence.
From observation of other cannabinoids like THC, certain genetic factors or personal preferences play a part in the time that it takes for cannabis extracts to be eliminated from your system. These characteristics may include:
Essentially, your body may not absorb CBD in the same way as your neighbor, and it may take a different amount of time for the compound to leave your system.
Remember, based on the most current research, the amount of time that CBD is likely to stay in your system is dependent on many factors.
