I recently tested positive for a small amount of opiates on a drug screen. I do not take any other drugs (other than what is listed in my question above). I was told a cd/ms drug test will be done to determine exactly what I took and how much. I didn't take any opiates so I'm a bit confused as to how they are going to tell what type of opiates I took when I didn't take anything. All I want is to clear this up. I am so upset about this whole ordeal. Has this happened to anyone else? Thanks for any help or advice in advance!
