Can you tell me how to pass a urine drug test in 24 hours after using cat?

Don't know what cat. Is as a drug. However, if you are using amphetamine like drugs, opiates, marijuana, benzodiazepines, pcp, Cocaine or other commonly abused drugs for which testing is usually done, then there is nothing you can do at this point. I would be more worried about having a drug problem than in being caught. What you can do is get help and be honest with yourself.If you try to beat test, they will find it.
