Marijuana: Common name for a drug made from the dried leaves and flowering tops of the Indian hemp plant, scientifically called Cannabis sativa. People smoke, chew, or eat marijuana for their hallucinating and intoxicating effects.
Opium: Is used primarily as a source of the drug morphine. Morphine is used mainly to kill pain arising from an accident or disease. It also controls coughing in diseases of respiratory organs.
Heroine: This is an artificial derivative of morphine. It is used medically and is perhaps the most dangerous of addictive drugs.
Cocaine: This is the only widely used local anaesthetic of plant origin, though there are several synthetic ones. An injection of cocaine deadens the response of nerves in small areas of the body to pain for a period of up to one hour.
Tobacco/Cigarettes: Tobacco is an agricultural product processed from the leaves of plants of the genus Nicotiana. It can be consumed, used as a pesticide, or at times as medicine.
Alcohol: Alcohol is a chemical which is present in varying amounts in palm wine, wine, beer, stout, and strong alcoholic drinks such as whiskey, gin, schnapps, etc.
Barbiturates: Medically recommended doses of barbiturates are used to induce sleep, relieve tension, treat ulcers, hypertension, insomnia, and a variety of mental disorders. An excess dose, taken over an extended period, causes physical and psychological dependence on the drug.
A person who uses a drug frequently, after repeated use, the person not only uses the drug again and again but is unable to do without the drug. This situation is described as addiction or dependence.
Once a person is addicted to a particular drug, he may find it difficult to do without it.
