There is a lot of new understanding on the length of time that THC metabolites stay in your system. I know of moderate users that have passed after 1 - 2 weeks of abstinence. Individual results will vary based on body weight, overall activity level, consumption level, etc.

Best advice is to go to Walgreens and pick up a home test to see if you can pass. It's a $15 insurance policy..... See pic below.
