Oral fluid drug screening, commonly known as a mouth swab drug test, is a method of detecting recent drug use. This type of test analyzes saliva for the presence of substances, with a focus on detecting use within a shorter window than urine or hair follicle tests. The detection window for cannabis in saliva is typically considered to be 24-72 hours after use, although individual results may vary.
The increasing prevalence of this testing method in workplaces and legal settings underscores the need to understand the factors influencing test results. Its ease of administration and non-invasive nature make it a practical option for employers and authorities. Historically, more invasive methods were more common, making oral fluid testing a relatively newer and more convenient alternative.
