As far as I know, MEPS uses 50 ng/ml on immunoassay and 15 ng/ml on confirmation GC/MS, same as most employers.

There are several supplements you can buy online - I've no idea if they work or not.

There are three things you can do that definately will help though.

1. Limit exercise between now and the test - THC is stored in adipose tissue. Exercise will skew the equilibrium toward fat cell breakdown, releasing thc into your bloodstream.
Actually, he's got over a week. He could benefit from aerobic exercise for a few days then stop on the 3rd or 4th and get lazy.

That's pretty much right.

You can't flush THC metabolites out of your system with water. It isn't like pressure washing the driveway. It is good to stay well hydrated but over doing it the day before the test isn't going to increase GFR.

Hair test are only about $20 more than a 5 panel urine test with GC/MS confirmation. They don't use hair testing in MEPS though.

Delore, many recruiters have instant tests they keep in the office to let those "questionable" prospects test to see if they can pass the real thing. They want you to make it in so they are usually pretty helpful. You can get your own instant test or come up with a creative story to see if you can get pre tested (I was at a party and there was some smoking going on in one of the rooms, heaven forbid I got some second hand smoke yada yada yada). Also, what is your height and weight and normal physical activity level? You can also add some soluble fiber to your diet like metamucil.
