A 45-year-old member asked:
Can you tell me if a urine drug test is clean, will a saliva test be clean as well?

Not necessarily: Different drugs are metabolized by different pathways. So, secretion of a metabolized drug in the saliva may be very different than a drug that has been metabolized and is now secreted in the urine. These pathways often involve the liver at some point, so if you have liver problems, it may affect test results also.
