The amount of time any drug can be detected in one's system can vary from person to person and test to test. It certainly can also depend on the amount of the drug taken and when it was taken relative to the time of the test.
Detection Time is the number of days after intake of a drug that an individual would be expected to excrete detectable levels of drug metabolite in urine. These are average times only - for each drug, detection may be possible (but less likely) for significantly longer than listed. Detection may be influenced by a variety of factors including dosage, frequency of use, liquid consumption, and individual metabolic characteristics.
Note: Detection times will vary depending on analytical method used, drug metabolism, tolerance, patient's condition, fluid intake and method and frequency of ingestion. These are general guidelines only, we cannot guarantee the accuracy of this information.
