Abstral is a narcotic and will show up in a drug test screening, so it’s important to inform your drug test administrator that you are taking or have recently taken this prescription. Abstral will stay in your urine and blood for at least 5 days, but will stay in your hair considerably longer. Drug test on your hair can show traces of Abstral and other medications for up to 90 days after your last dose. If you feel you or a loved one is suffering from substance use disorder, it’s not too late to stop drugs from taking over your life. The Recovery Village has well-trained staff standing by to answer your questions.
