CBD typically stays in your system 2 to 5 days. However, depending on your frequency of use - you can test positive for CBD depending on your use:
- 1-3 days for Infrequent users (less than 2 times/week)
- 7-21 days [after last use] for moderate user (several times per week)
- A month or longer after last use for heavy users (daily use)
How Long Does CBD Stay in Your Urine?
Many current drug tests look at a urine sample to see if it contains any prohibited substances. While there aren't many studies that take a look at how long CBD stays detectable in urine, one that did found some interesting information.
A recent study examined users who consumed capsules, oils, flowers, and other CBD products. The urine samples of the volunteers were examined after two hours, and they all came back positive. CBD levels were no longer detected after retesting urine samples 24 hours later.
Keep in mind that this is one of the few studies that look for CBD in the urine. If you're going to be drug tested soon, it's advisable to stay away from CBD for at least a week. Alternatively, exclusively utilize CBD isolate or broad spectrum extract products.
How Long is CBD Detectable in your Blood?
The focus of blood tests is on recent use. THC is only detectable in the blood for about 5 hours, but its metabolites can last up to 7 days in the body.
Taking CBD products that contain unknown quantities of THC would only produce a valid result if a lab test on a blood sample was performed during this short time frame.
Is it possible that CBD will cause me to fail a drug test?
While it's doubtful that CBD will lead you to fail a drug test, it's always better to be safe than sorry. THC is banned at the federal level and in most states, thus most drug tests seek for it (with the exception of a few).
It's vital to keep in mind, though, that CBD products can legally include up to 0.3 percent THC. However, because this amount is so small, it's unlikely to show up on a drug test. To be at risk of failing a drug test, you'd have to take a lot of full spectrum CBD oil, like 1,000mg or 2,000mg per day.
If you want to be extra cautious while still reaping the advantages of CBD, you'll be relieved to learn that there are several THC-free options available. THC is only found in full spectrum extract products. Buy CBD isolate or broad spectrum CBD products to avoid the chemical entirely.
Always buy from a brand that has its goods tested by a third-party lab when using CBD for the first time or transitioning to a new product. This ensures that the CBD contains a legal quantity of THC or none at all, allowing you to buy with confidence.
