There are very small amounts of THCa and THC in our products (not enough to be intoxicating). This is highly beneficial in most situations, but in rare instances it can lead to false positives for marijuana use. It does depend how sensitive the testing equipment is and how your body processes cannabinoids whether or not the THC will show up. In dealing with thousands of customers this has not been an issue, but it is best to check what kind of drug test will be required.
