What Are Drugs?

Drugs are a group of natural or synthetic substances that affect the central nervous system. The term “narcotic” refers to any substance that impairs consciousness and alters mental function. These substances often contain chemicals that induce drowsiness, sleep, or even loss of awareness.

Repeated use of these substances can lead to dependence syndrome—a set of behavioral, cognitive, and physiological changes that make the user strongly compelled to continue using the substance despite harmful consequences. Over time, this can develop into addiction and trigger withdrawal symptoms when trying to stop.

What Is Addiction?

Addiction is a compulsive and uncontrollable desire to continue using a drug despite physical, psychological, and social harm. The person may continually increase the dosage, which leads to:

• Psychological dependence

• Physical dependence

• Inability to function without the substance

• Withdrawal symptoms when stopping

Addiction affects the brain’s reward system, causing changes in behavior, decision-making, mood, and cognition.
