Home Drug Testing Tips & Advice

We are passionate about what we do and our goal is to make drug testing simple. With that in mind, we thought it would be helpful to explain a few things you should know to avoid getting a false-positive result. If you have ever thought your positive drug test result was a mistake, you could be right.

There are a few products that can cause a false positive on a THC test. Vitamin supplements, especially ones containing riboflavin can cause a false positive. Most supplements are made synthetically, but some companies produce riboflavin from hemp seed oil.  Ibuprofen can also cause a false positive for THC, barbiturates, or benzodiazepines. So if you’ve got a headache just before you take a home drug test you should grab some aspirin or acetaminophen instead.

Some people claim second-hand smoke will trigger a positive drug test result. This rumor is false. You would have to be in a very enclosed space with someone smoking heavily non stop to test positive for THC.

You might have heard about the rumor about poppy seeds and positive drug test results. People say if you eat poppy seeds, like on a bagel or in a muffin, you might test positive for opiates.  Well, this rumor is true. Poppy seeds actually contain trace amounts of opiates, like opium and codeine. Opiates can usually be detected in urine for up to 48 hours, so you should avoid eating anything with poppy seeds in that time frame.

Cold medicines, while tremendously helpful when you have congestion or sore throat, can lead to a false positive for amphetamines. This is because the primary ingredient in most cold medicines is Pseudoephedrine, which is a synthetic amphetamine and is often used to make drugs like meth.
