If you’re taking a CBD product, you may be concerned about how long it stays in your system. Maybe you’re faced with a routine drug test at work or are applying for a new position. In either case, you’re wondering if that CBD oil you’ve been taking for potential health benefits is going to show up on a drug test. Luckily, you don’t need to worry. CBD probably won’t show up on a drug test, and studies have shown that CBD doesn’t stay in your system for very long. Here’s everything you need to know about how long CBD remains in your system.
Does CBD Show Up on a Drug Test?
First things first: drug tests typically are not looking for CBD. Instead, they’re usually testing for another cannabinoid, THC. THC is the chemical that gives marijuana its psychoactive properties and causes users to experience a “high.” CBD, on the other hand, is not psychoactive and doesn’t get users high, so drug tests typically aren’t too concerned with it.
The problem is that CBD can contain traces of THC, some more than others. Hemp-derived CBD must contain less than the federally-regulated .3 percent THC. Hemp is a form of cannabis that’s bred for its low THC and high CBD content. In states that have legalized medical marijuana, you can find marijuana-derived CBD. Marijuana-derived CBD can contain more than 0.3 percent THC because it doesn’t fall under the federally regulated products. Not all manufacturers disclose whether their CBD is derived from hemp or marijuana, so you’ll need to do some digging.
It stands to reason that if you consume enough CBD that has a high THC content, it might show up on a drug test. However, hemp-derived CBD that contains less than .3 percent THC doesn’t provide enough THC to trip a drug test. To reach a concentration of 50 ng/mL of THC, a consumer would need to consume as much as 2,000 mg of hemp-derived CBD products or any CBD product with 0.3% or less THC content. Most people take much less than that, making it extremely unlikely that the average person – taking, for example, about 100 mg of CBD or less each day – would fail a drug test that’s testing for the federal 50ng/mL THC level. If you’re taking hemp-derived CBD, you’ll likely be in the clear.
That said, THC is stored in fat cells, so it is possible that low levels of THC could potentially build up over time and result in a positive drug test. However, it would likely require a significant daily intake of full-spectrum CBD products. There are several factors that can contribute to how long CBD stays in your system, such as your body weight and metabolism, your diet, dosage, how you take CBD, and how frequently you take CBD, and studies have shown that CBD can stay in the system for several days, possibly more than 10 days in some cases.
How Long Does CBD Stay in Your System?
You may still be wondering how long CBD stays in your system. Unfortunately, it isn’t a one-size-fits-all answer, but we can glean some answers from studies performed on the half-life of CBD. A 2014 study published in to the journal Epilepsy Currents found that CBD has a half-life of “about one to two days” when taken orally. The half-life of a compound is the amount of time it takes for the concentration of the compound in the body to be reduced by a half. In other words, if you take 10 mg of CBD, you’ll probably have about 5 mg in your body after one or two days. After four or five half-lives, the substance should have left your body completely. That means that CBD should leave your system completely within two to ten days, in most cases.
However, quite a few factors play into that calculation. The frequency of use, your metabolism, age, and weight may all impact how long CBD remains in your system. Additionally, the method you use to take CBD oil also may impact how quickly it moves through your body. Let’s look at the most common ways to get your daily dose of CBD and find out how long each should stay in your system:
- Sublingual oil. CBD oil and tinctures are one of the most popular methods of consumption. With sublingual drops, you hold the liquid under your tongue. This allows the CBD to be absorbed directly to your bloodstream and bypass your digestive system. CBD is processed by your body quickly through this method, which means it should also leave your body sooner.
- Consumables. Consumables are also a popular way to take CBD. They come in many varieties, including gummies, capsules, cookies, and other foods. When you ingest CBD orally, it must pass through your digestive system and be processed by your liver before it enters your bloodstream. That means it takes a lot longer than sublingual oil to take effect: approximately 30 minutes to one hour. This slower processing means it takes more time – generally speaking, about five to ten days – for the CBD to leave your system.
- Vape. Vaping is another way to imbibe in CBD. With this method, CBD is added to a vape pen or cartridge and is electronically heated. When you inhale CBD through vaping, the CBD enters your bloodstream immediately. Therefore, vaping is similar to sublingual oil in that you’ll feel the effects quickly, and the CBD should exit your system more rapidly.
