"I am a recent college graduate and am about to start my new job on the 20th. I have not smoked for a few weeks, but want to ensure that I can pass a drug test in time."
There are many variables that determine when THC leaves your body: for Marijuana for a Single Use, it can be out of the saliva in 24 hours and blood 6 to 24 hours . In a regular user, it can be much longer: up to 24hours in saliva and 7 days in blood tests.
For urine testing, it is too difficult to speculate in general, and depends on a person’s body fat, etc.
