How Long Does CBD Stay In Your System?
How long does CBD stay in your system?
If you’re using CBD oil, then you might have wondered “how long does CBD stay in your system?”. It’s a valid question! The general consensus is that CBD stays in the body for between 2-5 days, but this can differ for everyone, based on a number of facts.
It’s understandable that people who are subjected to drug testing for sport, work or other reasons are particularly interested in understanding how long CBD stays in the body. Cannabis drug tests are designed to detect THC; for full-spectrum CBD products to comply with the law the need to contain less than 0.3% THC. So for the most part, this is of no concern.
In today’s blog we ask the question, “how long does CBD stay in your system?” and we look at the factors that can influence how quickly CBD leaves the body.
How long does CBD stay in your system? The half-life explained.
Throughout this blog, you will see us refer to the ‘half-life’ of CBD. What does that mean? The half-life is a measure of the time it takes for the concentration or quantity of a given substance by half of the original amount. The term is commonly used in many applications of science.
The half-life of CBD is thought to be between 18-32 hours. Which means that within that time frame, the concentration of the dose that a person has consumed will have been reduced by half. In a further 18-32 hours, that half concentration will reduce by half again, and so forth until all CBD has cleared from the person’s system. This is how scientists arrive at the conclusion that CBD lasts in the body between 2-5 days (depending on a number of factors).
How long does CBD stay in your system? The dose rate.
As is the case with most other substances, the higher the dosage of CBD that you take, the longer it will stay in your system.
How long does CBD stay in your system? The frequency of use.
A review study conducted in 2018 found that the half-life of CBD was between 2 and 5 days for people who took a daily dose. In people who only use it occasionally, it clears from their system faster.
CBD is known to have a cumulative effect, and so it builds up in the body over time with regular use. It is also for this reason that it is recommended to try using CBD oil for at least a week to determine whether it is beneficial for the particular ailment or purpose that you are taking it for.
How long does CBD stay in your system? Your individual metabolism.
It goes without saying that we are all different. A number of factors influence each individual’s metabolism. Things such as your age, body mass index (BMI), and the amount of water you carry are just some such factors that can influence how long CBD stays in your system. CBD is a fat-soluble molecule, so it is stored in the body’s fat cells, rather than in water cells. This is why BMI influences the speed of metabolism.
How long does CBD stay in your system? Diet.
Diet matters. What you eat and how much you eat can influence how long CBD stays in your system for. Taking CBD on a full stomach slows its absorption into the bloodstream, as compared to taking it on an empty stomach, where it is absorbed and metabolized faster. High-fat meals also increase the absorption of CBD into the bloodstream.
How long does CBD stay in your system? The bottom line.
While how long CBD stays in your system will greatly depend upon the factors mentioned above, as a general rule of thumb, CBD is likely to leave the body after a week or two.
