Is there anything you can take or do to pass swab test?

Swab tests are able to detect use within the past few days.So stay away from drugs for at least 4 to 6 days. 7-12days is the best.Also clean your mouth big time, brush, gargle, and floss.And you can check these guys www.drugtestfriend.com I found it here and tried it myself (hair and urine tests and I passed with no problem) but they help for swab drug tests also.
