From what little I’ve read and gather...hemp oil is refined from the seed and referred to as hemp seed oil, and has no CBD properties in it. CBD oil, I guess derived from the leaves can and most likely will have a certain minute amount of THC, that can build up over time in your system and trigger positive test results.
It seems that the consensus is, nobody really knows, including myself, if hemp gummies can trigger a positive result. It seems the hemp gummies are CBD oil free, therefor would make them THC free as well. *f-wordk...I don’t know. I’m just trying to help the guy and do a little research for him...this dude is one helluva hydraulics/landing gear mechanic...he just ain’t no computer/google kinda guy.
