Trait controlled by the both environment and genetic factor. Usually, multifactorial traits outside of illness result in what we see as continuous characteristics in organisms, especially human organisms such as: height, skin color, and body mass.
I recently took a drug test for a job. I tested positive for opiates in my urine. I do not and have never taken drugs of any sort other than alcohol. I dont take any prescription drugs, how is it possible that this happened. I hade consumed some beer about12 hours before the test.
I've given plenty of urine drug screens to suboxone patients in the last few years, and have not had one false positive due to suboxone come up. The positive tests that did show up were due to the patient relapsing, not suboxone. This isn't to say that a positive for opiates can't happen, but the chances are very small.
