These drug tests are looking solely for THC, the component in cannabis that gets you ‘high’. Since Canntica contains zero THC, it shouldn’t be picked up in a drug test. Having said that, if you take very high doses of CBD (over 1000mg per day!) there is the possibility of a false positive in a urine drug test (which aren’t very accurate) but once the confirming blood test is done, the result should come back as negative.
