Narcotic drugs are drugs that have a narcotic effect on the central nervous system, are abused continuously or used irrationally, and are prone to physical dependence and mental dependence, and can become addictive. Commonly used narcotic drugs include Acetorphine, Acetamfetamine, Acetomethadol, etc. According to the international anti-drug conventions, active psychotropic substances are divided into narcotic drugs, psychotropic drugs, and other dependence drugs. In terms of natural properties, these substances are used rationally under strict control. They have a certain clinical therapeutic value and are called drugs. In terms of natural properties, if compulsively sought for abnormal needs, such substances lose their clinical therapeutic significance and are called drugs. The term drug is a relative concept, but of course there are still some that are no longer used as drugs due to their high drug addictive properties, and are therefore only considered drugs. Narcotic drugs can be broadly divided into: opioids, including opioids of natural origin and the active ingredients extracted from them; cocaine, cocaine, etc.; cannabis, including various preparations of cannabis; and some synthetic preparations for clinical use.
