retired longhaul trucker here ... you should pass OK, couple smokes a month, probably won't accumulate in your body enough to trigger the test ... THC stores itself in fat cells, that's why high levels of exercise help dissipate the THC concentrations ... BUT, if you're gonna be a truckdriver, you need to QUIT smoking pot ... sooner or later the tests will catch up to you, hopefully before you find yourself and others, in an emergency situation ... good luck :smokin:
