Drug Testing in the Workplace

Drug Detection Times
Drug detection times indicate the period after you last took a drug, that drug testing can reveal its presence or resulting metabolites in your specimen. Drug detection times are affected by frequency of use, type of specimen, test method, cutoff levels, metabolism, and other factors.

The table below was published in September, 1999, by the National Institute on Drug Abuse (NIDA). It includes commonly-abused drugs, such as marijuana, cocaine, hash, methamphetamine and other amphetamines. The type of specimen (blood, hair or urine) to which the table refers is not clear. But the drug detection times are within the ranges reported by other sources for urine analysis, and it's the most commonly-used drug testing method by Federal government.
