Quality of military urine test for marijuana?

it can detect it up to 5 months The military's urine test is state of the art. There are two phases to it. In the first phase, your urine sample will be taken to the Army Substance Abuse Program office on base and run through a screening machine. If it comes up hot, it's sent to a centralized lab where machines so sophisticated no one else has them are used. If your sample tests positive at the centralized labs...you've had it.
