How Long Does Cocaine Stay in Your Hair Follicle: Understanding the Science

Repetitive transcranial magnetic stimulation (rTMS) was recently proposed as a valid tool for therapeutic purposes in addictions, including cocaine use disorder (CocUD). We collected hair samples from nine CocUD patients at different stages from the beginning of treatments. Hair sample analyses revealed significant changes in the patterns of cocaine use, according to the negativity of urine screening tests and the clinical reductions of craving. In contrast to drug testing in conventional matrices, testing of hair may provide data on long-term exposure to drugs. For this reason, hair testing is a well-recognized method for forensic, legal, and clinical purposes, to assess one’s individual history of drugs of abuse [4]. Moreover, hair drug testing can be used in epidemiological and clinical studies to objectively assess repetitive exposure to a certain drug in specific patient populations [6].

Types of Drug Tests and What They’re Used For

A negative result indicates that you haven’t engaged in illicit drug use over the past 90 days. If you have an upcoming drug test and are concerned it might show evidence of your substance use, it can be tempting to quit the substance cold turkey and hope for the best. For example, if you drink heavily or use benzodiazepines, withdrawal symptoms can be dangerous and even fatal in some cases. It is important to remember that specific drugs included in the tests can vary. A 4-panel drug test means that the test is looking for four drugs; however, which specific drugs are included in the test is left up to the organization requesting the test and may vary. Weight can indirectly play a role in how long it takes a drug to leave your system.
