THC or tetrahydrocannabinol is the psychoactive cannabinoid found in both the hemp and marijuana plant. In order to be federally compliant, all hemp plants must be at 0.3% in THC. This is why full spectrum (containing all the cannabinoids) CBD oil won’t get you high. However, since full spectrum CBD oil contains THC, even such a low amount, it can cause someone to fail a drug test. THC builds up in our system, because technically it isn’t a drug or poison that our body immediately gets rid of. It actually uses THC for a multitude of biological reasons.
