Alcohol and cigarettes are legalized in most countries and inevitably available in abundance. Prescription drugs are harmful only if admitted in overdose or without a doctor’s prescription. Especially schedule X drugs which are classified as narcotics or nerve agents are most harmful to encountering overdosage. Though few drugs are illegal, there remain no restraints in their availability. The intoxication effects of each drug vary. Drug abuse showcases strong anti-social behaviour.
