How much hemp protein would it take to fail a drug test?

It would be almost impossible to fail a drug test from only taking hemp protein as it contains tiny amounts of THC when eaten in moderate quantities. Of course, if you take a lot of it, relative to your body weight, there is always a chance that you could test positive, but you would need to consume A LOT regularly. THC levels in most products are tested to make sure they are less than a specific ppm, usually 10-20 ppm
