In recent years, drug abuse has become one of the focal points of public attention. In order to detect drug abuse more efficiently, researchers in the scientific and technological world have made continuous efforts. One of the high-profile innovations is the use of hair for drug testing.
So, you might be wondering, why can hair be used to detect drugs? What's the principle behind this?
First of all, we need to know that hair is a part of the body and contains a lot of information related to the body's metabolism. When the body ingests drugs, these drug components circulate through the blood to reach the hair follicles. During hair growth, these metabolites are gradually deposited inside the hair, forming a characteristic timeline.
Drug testing is based on this principle. Using advanced analytical techniques, scientists can extract chemicals from a sample of a human hair, including metabolites of various drugs.
One of the advantages of this technology is that by analyzing a sample of a person's hair or body hair, we can understand drug use in the last 6 months. Hair testing can provide information over a longer span than urine or blood tests, which is important for long-term monitoring of drug abuse. Moreover, hair detection can screen a variety of drug types, reducing the complicated process of screening drugs;
In addition, hair detection has some other unique advantages. For example, hair samples are relatively easy to collect, virtually painless and non-invasive, and the samples are kept for a relatively long time. This makes hair detection a very convenient and reliable method of drug abuse monitoring.
Applicable scenarios of hair testing include, but are not limited to: addiction identification, community drug rehabilitation, drug use history analysis, abuse monitoring, and physical examination for special jobs (auxiliary police, civil servants, crew members, drivers, entertainment venue staff, etc.).
