Drug Testing for Heroine, Opium, and Prescription Opioids

With a few exceptions, these drugs last in the body only two to four days, regardless of amount and frequency of use. The exceptions include methadone, which lasts 6 to 12 days. Oxycodone, Percodan, Percocet, Tylox, Numorphan, Morphine, Lortab, Vicodin, Fentanyl, Davon, Tussionex and Talwin are all depleted within 8 to 24 hours, regardless of amount and frequency of use.

Barbiturates and Benzodiazepines

Short-acting barbiturates last in the body about two days while the long-acting barbiturates last as long as three weeks. The range of time for the latter category may depend on use history, so the longer, more frequent and heavier use would be detectable in the body longer than shorter, less frequent, light use. Benzodiazepines can generally be detected for seven to ten days.
