Homonym: Drug (Substance)
A drug is a substance that can alter the body's functions, either physically or mentally. Drugs can be natural, like those derived from plants, or synthetic, created in laboratories. They are often used for medical purposes, such as treating illnesses or managing pain, but some can also be misused, leading to addiction or health issues.
Drugs can be classified into various categories, including stimulants, depressants, and hallucinogens. Each category affects the body differently. For example, stimulants increase alertness and energy, while depressants can relax the body and mind. Understanding the effects and risks of drugs is essential for making informed choices.
