Everybody rids thc metaboites at different rates. It is impossible to plug numbers in and say for certain where one stands. What you should do is get some at home thc tests either through your local/chain pharmacy or on line (tons cheaper). Testing yourself is the only way to be sure. When you test yourself use your 1st void of the day since it contains the highest amount of thc metabolites. When you can test negative on your 1st void, you should be good to go.
