How long after ingesting drugs can the drug use be detected with a urine drug test?
A. Drug Detection Time depends on the drug used and the amount of drug used. The outer limit of detection for the commonly abused drugs is anywhere from two days to three days for most drugs, to 3-5 days for marijuana use. Claims that urine enable marijana detect for 30 days are exagerrated, and rarely occur. The soonest that drugs can be detected also depends on the specific drug. Urine typically can not detect drugs until hours after ingestion. The retention times below are only general guidelines. Physical condition, fluid intake, and method and frequency of drug ingestion all influence the time drugs stay in the body.
