Blood Drug Testing

What meds could I be taking that would trigger me to fail the marijuana part of a urine test?

I failed the marijuana part of a drug urine test and I was just wondering if cough medicine or anything else could trigger that?

3. "The chances of you getting a false positive depends on the quality of the laboratory that does the testing. There seems to be about 1,200 of these labs in the United States currently testing for drugs. Less than a 100 of these meet federal standards and most of the individual states do not regulate drug test labs. The number of false positives returned range from 4% to over 50%, depending on the lab. A concern here is that, if your company tests for drug useage, they are probably not required to use a certified drug testing lab, which means you have a greater chance of getting a false positive.

4. marinol that is a pill form of marijuana but, the THC is so much higher in the pill form that you would have to smoke it by the plant.
