According to the TEDS report, opiates are the primary substance of abuse and accounted for almost one-fifth (19 percent) of all substance abuse treatment admissions in 2007. Some common opiates are morphine, codeine and heroin, of which heroin is the major illegal drug. According to NSDUH, there were about 114,000 persons aged 12 or older who used heroin for the first time within the past 12 months in 2008.
Opiates is one of the five metabolite groups called SAMHSA-5 that can be tested for workplace drug testing under SAMHSA guidelines. The opiate drug tests detect the presence of codeine, morphine, and 6-acetyl-morphine. The presence of 6-acetyl-morphine shows recent heroin abuse.
Urine drug testing:
Urine test is a common method of detecting opiate and its metabolites in urine specimen. Morphine can be detected in urine for 2 days, codaine for 2 to 3 days and heroin for 3 to 4 days. The cutoff concentration for initial test of opiate metabolites is 2000ng/mL. The confirmatory cut off level for morphine and codeine are 2000ng/mL and 10ng/mL for 6-acetylmorphine.
Hair drug testing:
Many opiates can be detected using hair tests. Hair tests require a sample of hair about 90 to 120 strands. The standard hair screen uses the most recent 1.5 inches of growth for testing. Hair tests detect substance abuse over a long period. Morphine, codeine and heroin can be detected for up to 90 days using hair tests. The initial cutoff level for opiate metabolites is 200 pg/mg and confirmatory cutoff value is also 200 pg/mg.
Saliva drug testing:
Saliva tests are easy to administer and adulteration of the specimen can be avoided. Morphine and heroin can be detected in saliva for 1 to 2 days and codeine for 2 to 3 days. The initial cutoff concentration level for opiate metabolites is 40ng/mL. The confirmatory test cutoff level for Morphine and codeine are 40ng/mL each and 4 ng/mL for 6-acetylmorphine.
Opiate abuse continues be a serious threat to public health. The above information will surely help you to understand different methods of opiate drug testing and choose the better one to detect this harmful drug without much hassle.
