Hair analysis to detect drugs of abuse have been used by UK and Canadian courts, and hair testing for alcohol markers is now recognised in both the UK and US judicial systems. There are guidelines for hair testing that have been published by the Society of Hair Testing that specify the markers to be tested for and the cutoff concentrations that need to be tested.. Drugs of abuse that can be detected include Cannabis, Cocaine, Amphetamines .The hair follicle test is growing in popularity because it is less invasive than a urine screen, it is harder to falsify or tamper with the specimen, and the detection window is extended to roughly three months. Hair for testing can be collected from anywhere on the body, so the test can be utilized even when someone is bald or shaves their head. Because body hair grows at a different rate than head hair, some people have made the correlation that drug use can be detected in body hair for up to 12 months.
