use as well as the use of drugs and substances
not permitted in specific occupations or athletic
competitions.

checked at later date
Can test multiple people at one Need multiple devices to test
time multiple people
Person reading may be legally Takes away subjectivity
liable for incorrect results
Results may be bias towards an Removes bias as instrument
