ah. This was a one time thing they did in a store.. you held it in your mouth and a little thing on the side changed colors.
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!
