The hair follicle can easily detect the presence of marijuana, cocaine, amphetamines, opiates, and PCP. A person might be needed to undergo the drug testing process for things such as employment, medical purposes, or legal proceedings. Some companies might require a potential employee to take the drug test which is a part of their application evaluation process.

Employers might also organize random sessions for drug testing for the in-house employees to ensure everything is in place.

While some states ban the employers from this process implemented over their employers randomly, in order to organize a test the employer needs to provide sufficient evidence that aids their decision for testing any particular employee.
The courts might be required to opt for drug testing meant for the individuals that are on probation, child custody, domestic violence, and adoption. The healthcare providers might also request testing for the people that are at high risk of alcohol or drug misuse. However, it is crucial that the drug testing is conducted only after acquiring the written consent from the person.
The hair follicle test for the presence of drug can occur anywhere in a workplace, healthcare setting, or even at home. During this test, the examiner shall remove a minuscule hair sample that is close to the scalp of a person and then send the same to the laboratory for testing purpose conducted overnight. Certain foods and prescription medications like poppy seeds might contain compounds which lead to the showcase of a false positive result. The hair samples tend to undergo a 2-step process in order to ensure that the results are accurate to the core.
