Not sure if this is right category apologies if not. Basically about a week ago my partner took 2 of my co codomal 30/500 for an ankle pain. Two days later he got a random drug test at work and was suspended for which I am assuming was the co codomal. His employer is satisfied with his explanation but obviously he cannot provide a prescription for the tablets. Any advice would be great
Modern laboratory instrumental analysis allows detection of codeine, other narcotics and their analogues in blood and urine many days after ingestion of the drug. Detecting their presence after two days as per the OP's account, is a walk in the park for instrumental techniques nowadays. My laboratories can detect the presence of both codeine and morphine around a week after ingestion and sometimes longer.
