Sweat drug screen
There are also surface drug tests that test for the metabolite of parent drug groups in the residue of drugs left in sweat. An example of a rapid, non-invasive, sweat-based drug test is fingerprint drug screening. This 10 minute fingerprint test is in use by a variety of organisations in the UK and beyond, including within workplaces, drug treatment and family safeguarding services at airport border control (to detect drug mules) and in mortuaries to assist in investigations into cause of death.
