So been taking a lot of piss test for jobs and going and talking to the people who give you the test is interesting! You can learn a lot from them.

Like I found out that you need to watch what your eating! There are a lot of healthy snack food out there that have hemp in it! We all know it is legal but your piss test might say your doing weed! I was told this by one of the testing places guess the military has kicked people out because of it " Per the Air Force guy" so just be careful what your eating! A lot of the Kind health bars you can find at Walmart have hemp in it also seems like it's being used a lot more in health food. Just a FYI

Many tests will show positive even on a "negligible" presence.  Eat a poppy seed muffin and take an opiates test - it'll show positive. Only a more expensive quantitative test will indicate that the presence was a trace amount not linked to illegal use.

I had this exact thing happen to me.  Ate a poppy seed muffin got pulled for a random drug test on a job site.  Me and one other person failed the test.  We argued it and the company said they will send it out for a quantitative test and it came back as trace amount to small to be linked to illegal use.

I always thought this was an urban myth. Crazy!

I can confirm. I have also popped positive for opiates from eating poppyseed bread.

No kidding... that's what I always thought too.

I picked up a few of those Kind bars this week to try, LOL.

No shit; I did to.  I need to take a look at the ingredients in the kind bars as someone above mentioned they contained hemp seeds.  

Pretty sure you won't test positive for THC by eating hemp as they test for the byproduct of metabolized THC.

When I tested for the Air Force they had flyers all over the place about this they went so far to make sure the PX does not sell anything with hemp in it.

Mythbusters did it
