I haven't smoke weed in a mouth and a half will i pass a urine test

The chances are good that you'll pass.

If you were a heavy daily smoker before you stopped, there's a slim chance that there are still enough metabolites in your system to show up on a test, but if you are only a "casual" smoker, you'll be OK.

(A hair test will show drug use from months ago (depending on the length of your hair))

you should it takes about a month for it to pass your system
