how does a mouth swab drug test work? is it more accurate than a urine test?

Not Medical/Legal Advice: Saliva testing analyzes an oral fluid sample for parent drugs and their metabolites. An absorbent collection device is placed in the mouth and the saliva collected is screened for drugs of abuse. Samples are checked to verify the saliva is human and undiluted.

According to Forensic Fluids Laboratories, oral fluid testing can detect drugs anytime, from immediately after the most recent use, up to three days after use. Conventional drug testing with urine cannot accurately detect usage in the first four hours after use, thus making saliva superior for post-accident testing.
