how long does cbd oil last in your system

Your method of intake can influence how it affects you as well as for how long it lasts. Popular methods and forms of CBD include:

According to the Mayo Clinic, THC metabolites can be detected for as long as 15 days post-administration among frequent and daily users. However, the research also suggests that these numbers can vary based on the dosage.

How Long Does CBD Stay In Lab Tests?

If you pass a drug test after taking CBD, it doesn’t necessarily mean you have traces of THC in your system. It may just mean you’re below the detection level.

Furthermore, some tests are more effective at detecting THC and for longer periods of time. The type of drug screening you’re administered – and how long after you last took CBD – could influence whether it’s detectable.

There are many different factors to consider that influence how long CBD stays in your system as well as how it affects you. How long it lasts and is detectable is not the same for everyone. It can depend on:

Inhalation is also an effective delivery method for CBD due to its rapid absorption and the efficiency of the lungs at transferring CBD into the bloodstream. Whether you’re smoking a high-CBD strain or taking a draw from a CBD vape pen, the interaction with the body remains the same. When CBD is inhaled, the cannabinoids are sent directly to the lungs, where they are rapidly absorbed into the bloodstream and put into circulation.

Bottom line: Whether you’re ingesting CBD oil or CBD-infused edibles, it ultimately goes through the same lengthy digestive process, reducing the total CBD concentration in the bloodstream. With ingestion, it could take anywhere from one to two hours before the effects of CBD finally set in. From there, you may feel the effects for one hour to several hours, depending on the dose and your response to CBD.

A 2018 review of existing CBD studies found that the estimated half-life of CBD was two to five days for those who took a daily oral dose. Other delivery methods delivered varied half-lives.

I on the other hand use CBD for anxiety and as a sleep aid. When I start to feel that turning in my stomach and start to get anxious, I will break out my CBD vape pen and take a few puffs. Within a few minutes, I start to feel my worries wash away. Then, most times after about 20 minutes, I can function properly again and get on with my day.

The period between doses is roughly 9 hours apart for her. She does occasionally have a third dose in the afternoon on days when she is visiting her grandchildren. The method of ingestion for this afternoon dose is usually a CBD mist which she takes Sublingually by squirting a few sprays under her tongue. Sublingual CBD use is supposed to be the second quickest way to feel the onset of effects after smoking or vaping.


CBD oil has a much shorter half-life than its cousin THC. THC can be found when tested for in the body for up to 30 days after use. THC metabolizes for everyone differently, but generally, if you are a moderate to heavy smoker, expect for it to show 14-30 days after use.

Depending on the day and how everything is going, I will notice the effects of the CBD start wear off after around 2-3 hours. I should note that I am 6’1 and weigh 200lbs. I am also quite active—getting 4 to 5 days of exercise in a week. So my metabolism is going to be quite high compared to my grandma’s

This would be eating or drinking CBD in a variety of ways, so that it’s passed through the stomach, then to the liver before entering the bloodstream. This method of consumption is known to bring the slowest onset of effects, but also last the longest. Taking CBD pills or capsules or adding CBD to food through an oil tincture are the most common ways of ingesting CBD.
