However, little research has examined how much a person must smoke to fail a drug test While hair tests are highly sensitive to cocaine, their sensitivity to pot is not well established Alternatives: The shortcomings of drug testing can be avoided by performance tests that measure actual concentration and reaction time instead of chemical residues Swab tests use fresh saliva from the mouth using a Q-tip or a swab Passive inhalation of marijuana smoke and urinary excretion of cannabinoids In vivo adulteration: excess fluid ingestion causes false-negative marijuana and cocaine urine test results J Anal Toxicol It can only indicate recent use of drugs Although further study is needed on the long-term health effects of marijuana use, short-term effects include impaired motor coordination and perception, as well as slowed learning and decreased short-term memory 9 Home tests can help people test themselves for the presence of cannabis in their system .
