Once the drug is taken, it will leave traces in the urine, blood, saliva and other biological materials, which could be used as evidence to identify illegal drug use. However, different types of samples have different retroactive periods. For example, generally, the retroactive period of drugs in urine is no more than 3 days, and in blood is less than 24 hours. Once exceeded, no drug components can be detected.

Hair, as a legal biological sample, has incomparable advantages. There are dense capillaries around the hair follicles. Drug components or metabolism products in the blood enter into the hair follicles of the scalp during the growth of the hair, and fixed by keratin in the hair. The hair containing drugs will grow out of the surface of the scalp in about 3-5 days. According to this mechanism, we can infer the type, time and dose of drug abuse and detect the trace amount in past months.

ILG-100 Rapid Drug Detector adopts advanced Quantum dot immunochromatography technology. Rapid and accurate detection of morphine, methamphetamine(“Ice”) and ketamine (commonly known as K powder) in hair can be easily completed in 6-10 minutes.
