While the DoD has stated CBD products are not permitted for active members, the drug tests administered do not look for CBD, they look for THC. And the topical administration of CBD products will not enter your bloodstream regardless.
No. They test for THC. However, THC can be present in CBD products, and if you're not careful you can test positive after prolonged use of this "full spectrum" CBD oil. CBD isolate does not contain THC.
