If you’re a Commercial Driver’s License (CDL) driver, you probably already know that the use of certain drugs, including marijuana, will disqualify you from driving a commercial vehicle. But what about oils made from cannabis, such as hemp oil and CBD oil? Does hemp oil show up on a drug test? Read on to learn more.
Hemp oil is made from the hemp plant, a species of cannabis. There are two main varieties of hemp oil: hemp seed oil and cannabidiol (CBD oil). Hemp seed oil is made from the seeds of the hemp plant and contains little to no tetrahydrocannabinol (THC) and no active CBD. Hemp seed oil is usually used for nutritional purposes, as it contains vitamins, minerals, and essential fatty acids. CBD oil differs from hemp seed oil, but the two terms are often used interchangeably. CBD oil is made from the stalks, leaves, and flowers of the hemp plant. It contains a higher percentage of CBD than hemp seed oil does, and it can be used for medical and recreational purposes.
Now that we’ve defined hemp oil, we return to our original question: Does hemp oil show up on a drug test—in particular, a Department of Transportation (DOT) drug test? The DOT does not allow the use of cannabis with over 0.3% THC. However, hemp oil generally contains under 0.3% THC, and it doesn’t affect a person unless taken in extreme amounts, making its use acceptable in the eyes of the DOT. Unless taken in extreme quantities, hemp oil—including CBD oil and hemp seed oil—does not usually show up on drug tests. This is because drug tests test for THC, the active ingredient in marijuana; the level of THC in hemp oil is much lower than in marijuana—generally too low to be detected.
It’s important to keep in mind, however, that CBD manufacturers cannot always guarantee their products’ THC levels are below 0.3%. Thus, if the hemp oil you’re using contains any THC, there’s always a slight chance you’ll test positive for marijuana. Use hemp oil at your own discretion, and if you’re concerned about testing positive, consider taking a non-DOT drug test to confirm that your THC levels aren’t too high.
As a CDL driver, you must always be careful to avoid substances the DOT doesn’t allow because the consequences of a violation are serious. Be prepared for a random DOT drug and alcohol test whenever you’re on duty.
