About 20 years ago, drug abuse and drug smuggling became increasingly serious all over the world. Faced with this grim situation, the United Nations held a ministerial conference on narcotics and illegal trafficking in Vienna from June 6, 65438 to June 26, 987. More than 3,000 representatives from 138 countries attended the conference. The meeting put forward the slogan "Love life, don't take drugs". June 26th every year, the day after the opium was destroyed in Humen, is designated as "International Anti-Drug Day".

There are ten kinds of drugs in the world, mainly opium, heroin, marijuana, cocaine, amphetamines, hallucinogens and so on. Among them, heroin occupies the third and fourth places, that is, drugs No.3 and No.4, which are commonly called "Heroin No.3" and "Heroin No.4" internationally. Because of this habitual name, people mistakenly think that there are heroin 1 and 2, but heroin 1 and 2 are actually morphine (basic substance) or morphine.

Generally speaking, drugs have the following characteristics: (1) There is an irresistible force that forces smokers to keep using drugs and get them by hook or by crook; (2) continuous use is easy to increase the dosage; (3) Mental and physical dependence on drugs, withdrawal symptoms after drug withdrawal (that is, withdrawal symptoms will occur after drug withdrawal); (4) It will produce harmful results for individuals, families and society.
