A friend of mine smoked the day of his swab test and passed. Said he just didn't let the swab really touch the inside of his mouth... It's more of a thing you have to hold in your mouth then something they do.
thathippiekid Reviewed by thathippiekid on . how do you pass a swab test?? I have a drug test coming up in a week... I've been taking Niacin & Goldenseal for a week & a half. Took one of those home drug tests & failed it.. been smoking for about 43 yrs on a daily basis.. have quit for about a month now.. I thought the test was going to be a UA but instead they do a mouth swab... where they use your saliva... does anyone know of how you would pass this type of test? really could use some help here!
