False positives are more common than one would like to think. Labs make errors. Immediately get a repeat test.
I have a relative that's a cop who  this happened to.His repeat  test came back negative..but it may be up two years before he gets his job reinstated...beauracracy at it's finest.

   If you had no dope in your system then you need to go to a Dr and explain what happened and take a drug test you will no for sure then.  Sometimes mistakes happen.

If you have done it in the past, within a year I wiuld say, and you lose weight, you could come up with a pos u/a. Thc is stored in the fatty cells, and burning fat can release some thc. It happened to my husband after being clean 5-6 months, and getting really sick so that he lost a lot of weight. Try telling this to a po, tho. Either way, ask for a new one soon.
