There can be many factors—such as drug half-life, hydration status and frequency of drug use—that can affect how long certain drugs remain detectable in urine. For instance, some drugs can be detected from 2 to 4 days; some drugs can remain for months (like marijuana). Drugs that have a long half-life may also remain in your systems for a longer amount of time.
Our test measures for 6 drugs via urine testing:
Amphetamines including methamphetamine. Typical detection time in urine is up to 2 days.
Cannabinoids (Marijuana/THC). For just a single use, typical detection time in urine is from 2 to 7 days. However, if use is chronic, detection time in urine may be extended.
Cocaine. Typical detection time in urine is up to 4 days.
Opiates/Opioids. Typical detection time in urine is up to 4 days.
Oxycodone. Typical detection time in urine is up to 4 days.
Phencyclidine. Typical detection time in urine is 2-3 days but can be more than a week in chronic users.6
