Unlike urine tests which can only detect recent use, these hair tests can detect historic use. Head hair grows at an average of 0.5 inches per month, so depending on how long your hair is, you could detect usage of several months or even years.
Hair detection has unique advantages in the field of drug testing. Hair can provide long-term medication information that is not available in other biological samples such as blood and urine. Hair samples are relatively easy to take, easy to carry, and easy to store for long periods of time. The slow metabolism of drugs in hair can persist for a long time, and these factors provide better conditions for drug analysis.
Cocaine is a potent central nervous system stimulant and a local anaesthetic. Initially, it brings about extreme energy and restlessness while gradually resulting in tremors, over-sensitivity and spasms. In large amounts, cocaine causes fever, unresponsiveness, difficulty in breathing and unconsciousness. Cocaine is often self-administered by nasal inhalation, intravenous injection and free-base smoking.
