Of all deaths in the U.S. each year, half are caused by substance abuse. Substance abuse is pervasive. About 33% of all Americans smoke cigarettes, 6% use illicit drugs regularly, and about 14% of all Americans are alcoholics. The consequences of substance abuse include heart disease, cancer, stroke, chronic obstructive lung disease, cirrhosis, trauma, and familial, social, legal, and economic difficulties.

The utilization of medications or other substances with intentions differing from their prescribed purposes, often to induce intoxication or modify emotions. Frequently abused substances include stimulant drugs, solvents, and adhesive substances. Issues can emerge from unfavorable reactions or the addictive nature of the substance, leading to potential dependencies.
