Background
Abuse of illicit drugs has become a very serious social problem. Currently, the number of drug abuses of men is about 2700 ten thousand and the number of drug abuses of men is about two to three times of that of women. Among the abusive classes of illicit addictive substances, cannabinoids are the most widely abused globally, with an prevalence of about 3.8%. Second, opioids, amphetamines, ecstasy and cocaine, with prevalence rates of 1.05%, 0.7%, 0.4% and 0.37%, respectively. Of the abuse modes, intravenous injection is the most prevalent mode of abuse, especially in countries and regions of eastern and southeast europe. The abuse mode can cause the blood-borne diseases such as AIDS, hepatitis B, hepatitis C and the like to be widely spread among drug-taking people, seriously harms the human health and increases the national economic burden.
After the reform is opened, along with the development of economic level and the advance of trade, the drug-taking phenomenon starts to spread and flood. At present, illegal criminal activities related to drugs exist in provinces, cities and municipalities all over the country to different degrees. At present, the abuse situation of Chinese drugs is developed towards diversification. The total number of drug abuse crowds is increased sharply, the drug addicts have the characteristics of youthfulness, the abusing amount of various novel synthetic drugs such as amphetamines and ketamine is increased rapidly, and the traditional drugs still keep a higher abuse level. In addition, drug abuse places are diversified, and common use phenomena exist in various entertainment places such as bars, clubs and the like.
The consumption or abuse of forbidden drugs is a public health and social problem worldwide, which not only seriously harms human health, but also brings high crime rate, economic loss, social public safety, public health and other problems to the society. At present, China mainly adopts the method of strengthening the control of virus-making raw materials from the source and strengthening the information work at the same time, and arranges the public security personnel to be hidden in virus-making pits as the bed bottom. However, this type of investigation requires a lot of manpower and material resources, and a lot of time is consumed to investigate and obtain evidence, and the safety of the public security officer who is under bed cannot be guaranteed. Particularly for drug-making and drug-selling nests which are in the deep mountain and in the forest and have good hiding performance, the investigation work is slow, the drug-making and drug-selling places cannot be accurately positioned, the drug-making degree cannot be known, and the instant and effective information is difficult to obtain.
