Drugs are a global disaster and the enemy of all mankind. At present, the increasingly serious drug tide in the world not only seriously endangers human health and corrupts social atmosphere, but also directly leads to and induces various crimes, threatening global political stability and economic development. It has become the common aspiration of people all over the world to contain, reduce and eventually eliminate drug crimes, and combating drug crimes has become a severe task faced by judicial organs all over the world. In the process of detoxification, we found that many drug addicts were tricked into taking drugs because they didn't understand drugs, and some abused drugs for the purpose of "treating diseases", and as a result, they became addicted to drugs and could not extricate themselves! In order to educate teenagers, so as to achieve the purpose of understanding drug knowledge, detoxification and anti-drug, our hospital's drug rehabilitation center has formulated this manual, aiming at strengthening anti-drug publicity and education and raising the awareness of the whole people, hoping to play a certain role in controlling the spread of drug abuse.
