Detecting Marijuana Through Urine Testing

Approximate times for testing positive versus frequency of use.


In response to questions referring to the time it takes the body to cleanse itself from detectable urine traces, according to a national report titled, "Drugs, Crime, and the Justice System", (published from the Bureau of Justice Statistics, U.S. Department of Justice):

Single Use : 3 Days

Moderate Use (4 times a week): 5 Days

Heavy Use (Daily smoking): 10 Days

Chronic Heavy Use: 21-30 Days

Although do keep in mind that there are many factors that effect the outcome of the tests (potency of drug taken, testing methods, metabolism, etc.) so this is just a estimate figure-so be careful out there.
