Illegal drugs are drugs which have controls on them by a government and are illegal in certain situations (a person is not allowed to have them). A drug is any chemical designed to affect the human body. A psychoactive drug is a drug that affects the brain. Some controlled drugs are allowed if you have permission (called a "prescription") from a doctor. Other drugs are illegal - meaning you are never allowed to have them. Individual countries and places have different laws about different drugs, and there are also international treaties against some drugs. The most used drugs are not illegal.

One theory suggests there is a genetic disposition which predisposes certain individuals toward substance abuse. Another suggests substance abuse is learned there for people subjected to substance abuse by those around them begin to copy the same behaviors. Substance abuse might start out as a bad habit but when and if addiction develops it manifests as a chronic debilitating disease.
