How does a saliva swab drug test work?

Answer

A saliva swab drug test is one of the most ineffective drug tests used. Some of the chemicals in marijuana can be detected with a saliva swab test for 1-3 days after use and no more. You are given a spongy swab that is attached to a stick, very similar to a lollipop and you put it in your mouth for a few minutes being sure to rub it up against the inside of the cheek. The sponge is then tested for chemicals that may have been left behind from drug use.
