If the line is faint once you take your test, then you might want to drink a healthy amount of gatorade and water before your test, but not enough to "dilute" the sample which would make employer's suspicious if you are for some reason (though doubtful) dirty. I would say you were 110% alright if you were "skinny" but people that are overweight have a shitty time expelling the THC from their system, and there have been situations before where people like that still test positive after quitting for 60 days. I'd say you'll be fine though
