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.
no
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.
No.
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.
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.
