There are many types and various categories of drugs that are difficult to classify into a single category. The chemical and pharmaceutical industry introduces new compounds every day, which differ from each other in terms of effect and composition. One of the common classifications is as follows:
A: Substances that cause mental and physical dependence:
– Opium and its derivatives such as heroin, morphine, cocaine, etc.
B: Substances that only cause psychological dependence:
– Cocaine
– Amphetamines
– Hashish
– Marijuana
– Catha
– Hallucinogenic drugs
– Volatile liquids (inhalation)
This classification helps us better understand how different substances can affect the human mind and body.
Now let’s discuss the definitions of each type of drug and their methods of usage.
Opium
Opium is a substance obtained from the sap of a plant called “poppy,” which grows in temperate regions and has beautiful dark red flowers. This substance is extracted from the poppy flower by making incisions in its capsule. At the beginning of its release, it is a white sap, but upon exposure to air, its color changes and becomes brown and hard.
Opium usually has a brown color and a paste-like consistency, and its smell is often compared to that of urine or ammonia.
Usage methods: Smoking, swallowing, and mixing with tea or coffee.
Heroin
Heroin is one of the most powerful addictive drugs and has earned names such as “the white devil” and “the round of death.” Heroin is a white crystalline powder that is extracted from morphine through a distillation process.
