Poison is generally a drug that induces addiction. The word drug here is a broad concept, which mainly refers to crow slices, heroin, ice, etc. abused by drug addicts, and also includes dependent natural plants, cigarettes, alcohol, solvents, etc., which is different from medical drugs.
Drug-making products refer to articles used to make drugs that are drunk and intoxicating. Some poisons can be obtained naturally, such as crow slices, which are natural products extracted directly from immature poppy fruits, but most poisons can only be obtained through chemical synthesis. These basic raw materials for pharmaceutical and chemical production are what we call drug-making products. Therefore, toxic substances are not only raw materials for medicine or chemical industry, but also preparations for making toxic substances.
