Using someone else's urine, who has used pot, for the drug test would give a false positive.
what medications cause a false positive on a drug screen for marijuana?
It just gave me a false positive for marijuana for a drug screen for a job.
yes it can be a false positive.
Any drug that contains THC (e.g., Marinol) and any food that contains marijuana (e.g., "weed brownies") will cause a positive THC test.However, there are some products that can cause a false positive for THC, such as ibuprofen (Advil, Motrin, etc.), naproxen (Aleve), hempseed oil, and even riboflavin (vitamin B2).This does not mean that taking those products will cause a false positive. Sophisticated drug tests won't be fooled.

Eucalyptus does NOT contain THC. Eucalyptus has some of the same characteristics for marijuana such as color changes and chloroform separation, which can cause a false positive on a drug test.
i have herd that eating poppy seeds that are found in pastry cakes can cause a false positive test for meth. poppy seeds cause a positive for marijuana - not meth. Actually you are both very wrong. Poppy seeds can cause a false positive for opiates(heroin, morphine, etc). Opiates are made from the poppy plant. Wow who ever said these top two are STUPID. I am speachless.
It should not cause a false positive on a drug test.
