Stop smoking for up to 72 hours and you'll pass the oral swab test. :thumbsup:

Also brush everywhere in your mouth real good. Teeth tongue and especially the roof and cheeks. Also on top and under your tongue. If they allow you to insert the swab, just touch inside your mouth lightly and pretend to rub it around. Just get it wet on you cheek.
