If you are worried about testing positive on a drug test after consuming hemp seeds, there's no need to worry.  Hemp hearts come from a plant that is similar to, but not the same as, marijuana. The hemp plant contains 0.3% THC - significantly lower than marijuana which can contain up to 30%. Jolene Formene, staff attorney for the Drug Policy Alliance points out that consuming hemp seeds will not make you high; minimal amounts of THC may be found when consuming them and studies have determined that it would be difficult to detect such low levels in federal drug tests.
