How long does marijuana stay in your system?

California NORML's Drug Testing Tips -
Dealing With Urinalysis on Short Notice

"While NORML strongly opposes drug use on the job, we think no one should be forced to submit to urine testing, especially for marijuana. Aside from launching a legal challenge, your best defense against urine testing is to be clean. Unfortunately, this may be difficult since urine tests may detect marijuana 1-5 days after an occasional use, 1-3 weeks in regular users, and 4-6 weeks in multiple daily users.
