Here is the best advise you will get: Go to a head shop (or browse the internet) for the THC at-home urine test. They are sensitive to the same detection levels as the employer-driven lab tests. You can find them for like $6 a test. Or you can go to pharmacy and buy one for $18.

I'm an everyday (though relatively light) smoker. When I quit, I find that I can pass a test after 14 days of no-smoke. I've even tested clean after 11 days of no-smoke. I'm in decent shape, although I carry a beer gut and love handles.

So get rid of all the uncertainty and get yourself tested before you go to any job interview.

Here's another gem of wisdom: The only time urine tests are observed is when it is mandated by court (i.e. for parole). The urine tests for pre-employment screening are NOT observed in person. They may require you to put your wallet, keys, phone, and valuables in a locked box before going into the bathroom. But no one will ever watch you urinate.

The nurses at the test clinic can never check what you sneak in the creases of your taint. You only need 40 ml of liquid for the pee cup. Clean, body temperature pee can easily be sneaked into a pre-employment drug test.

Get clean pee from a trusted friend or get the powder from the internet. This is the surest way to pass when your body is full of THC.
