Hey quick question fellas, I work P/T at my job im work one week and Im off the next. Well this last week I worked im hurt my back really bad, didnt even know it till later that evening, but here I am off till my next week. Now I have taken some of my mothers tylenol #3 with codeine, which will show up in a drug test. If I call work and tell them I hurt my back its policy to send me for a drug test which will show the codeine which I dont have a prescription for which means I lose my job. How long does it take for codeine to clear my system??? Please only answer if your sure my job depends on this LOL I thought it was 2-4 days but I need some def answers. Thx
