What is a Drug?
A drug is any substance that causes physical or mental changes in the body. They can benefit the body by restoring health in a diseased situation, change someone’s state of mind or mood, or make one dependent on it in order to cope with life.
Drugs that are produced legally are called Licit drugs, for example, paracetamol, antibiotics, alcohol, caffeine, and nicotine. Those that are not permitted by the law are called Illicit drugs, for example, Indian hemp, cocaine, heroin, etc. Drugs used for the treatment or prevention of diseases are called Medicines.
