Will THCA show on a drug test?

Yes. Drug tests screen for THC metabolites, and heated THCA products produce exactly the same metabolites as dispensary cannabis — a standard test cannot tell legal hemp flower from anything else, and "it was federally legal" does not change a lab result or an employer’s policy. Detection windows vary from days to weeks or more depending on frequency and body. We publish no beat-the-test tricks, ever, because they range from unreliable to fraudulent. If you are subject to testing, the only honest answer is that these products are not compatible with that.
