This test will allow you to figure out if a drug from the opiate family has been recently used. The test will yield a positive result when concentrations of morphine exceed 2000 ng/mL. Morphine is excreted un-metabolized, and is also the major metabolic product of codeine and heroin. Morphine, codeine, and heroin are generally detectable in the urine for several days after use.
Opiates are extremely addictive. You can learn more about Heroin at the National Institute on Drug Abuse website. This opiates drug test uses a urine sample to find out if an opiate has been used in the past few days. It is 99% accurate, simple to use, and provides results within 5 minutes.
