marijuana? yes.
30 days
probably in a hair test but not in urine
Obviously not
yes
you don't
No it does not. My friend smoked a day before his drug test and it didn't show.
21days. But you can shorten that time by drink a lot of pure orange juice
not yet before you do test yourself with a test kit from a drug store
yea
I don't know how much you smoked before you stopped, but with a 30-day no-weed window I'd say you're safe.
nope, well, kind of. You can fool the test by using fake urine or by drinking a lot of water to dilute your urine the night before.
