Drug are those substance which produce physiological effect in our body. The effect maybe good are bad but drug produce it. So if we take for certain effect like for pain etc its good and will benefit for us. But some people used it for addiction which cause demagh to our body in its known as drug abuse and which is prohibited in most countries. So i want that with any prescription the norcotics and other opidos and antidepressant should be not given to any person.
