Drug use and drug addiction are major public health concerns worldwide. Understanding what drugs are, how addiction develops, and how it affects individuals and societies is essential for awareness, prevention, and recovery.
What Are Drugs?
Drugs are substances that alter the normal functioning of the body and mind. They can be legal (such as prescribed medicines or alcohol) or illegal (such as heroin or cocaine). While some drugs are used for medical purposes, misuse can lead to serious health risks.
What Is Drug Addiction?
Drug addiction, also known as substance use disorder, is a chronic disease where a person becomes physically and mentally dependent on drugs. Addiction affects the brain’s reward system, leading to compulsive drug use despite harmful consequences.
Types of Drugs
Drugs can be broadly classified into:
1. Stimulants – Increase alertness and energy (e.g., cocaine, amphetamines)
2. Depressants – Slow down brain activity (e.g., alcohol, benzodiazepines)
3. Opioids – Relieve pain but are highly addictive (e.g., heroin, morphine)
4. Hallucinogens – Distort perception of reality (e.g., LSD, psilocybin)
5. Cannabis – Alters mood and perception
6. Prescription drugs – Painkillers, sedatives, or stimulants misused for non-medical purposes
