What Do OPI Drug Tests Screen For

There are many different types of home drug testing kits which screen for a wide variety of substances with different origins. One of which is an OPI drug test.  As the abbreviation suggests this form of testing looks for opiates and opiate derived synthetic versions (OPI). With substance abuse numbers on the rise for opium, heroin, and the fastest growing addiction, narcotic prescription pills, it’s become relevant to screen for these substances which would have gone undetected in the past.

On average it takes between 2-3 days for the human body to breakdown and rid itself of opiates once they are ingested; meaning a person can only show positive on a urine drug test if they used in the last 72 hours give or take (the true time of how long opiates will stay in your body depend on a large list of individualized factors). The detox time or the length of time it takes Opiates to be expelled from your system is faster since they tend to be water soluble, in contrast to the fat soluble THC which can leave traces in your urine up to 30 days since last use. Opiates are classified as drugs that are derived from (or based on) the resin excreted by the Opium poppy; which includes Morphine, Opium, and Heroin, Vicodin, Oxycontin, Oxycodone, Percocet (NOTE: the last 3 substances will only appear in opi drug tests when high doses have been consumed. If you are concerned about Oxycontin abuse, please use an OXY drug test which will detect much lower metabolite concentrations in the urine stream.)

However what does OPI drug tests screen for? Opiate drug testing analyzes a person’s urine for a variety of Opiates and sometimes drugs that have “opiate-like” effects. Usually when a person is subjected to this form of testing they are looking for the big three listed above; Morphine, Opium, and Heroin. Unfortunately over the years the testing palette has expanded to include Oxycodin, Oxycodone, Paracetamol , Tylenol 3, Morcap, Codafen, and Roxanol. It’s important to remember that previously testing of “legal” drugs was unheard of, but with the rising number of people abusing prescription drugs employers aren’t taking any chances.
