it's different for everyone. thc stores in your fat cells, so the more weight you have the longer it stays.

i've beaten drug tests where i've smoked constantly up til 2 days before and beat it naturally by drinking a lot of water before i peed. granted, this was one of those tests you dip into the urine and wait for the lines to show up.

if you really only smoke that much, unless they catch you within 72 hours you should be good. check out erowid.

hope this helps.
