Hemp Protein Powder is produced when whole hemp seeds are cold-pressed to expel the oil, leaving behind a dry "cake." This cake is then milled at low temperatures to remove some of the fiber and produce a concentrated form of protein. We have not tested it in drug tests, however according to this link here, drug tests have not been affected with the consumption of hemp seeds since there is no measurable THC in the seeds or protein that we consume.

However, if you are worried, then better play it safe.
