What is the most commonly used drug among all age groups?

Alcohol is the most commonly used drug among all age groups due to its widespread legal status and social acceptance across various cultures. It is easily accessible, and its consumption is often integrated into social events, celebrations, and daily activities. This prevalence contributes to its high usage rates when compared to other substances. While tobacco, marijuana, and cocaine have significant usage rates, they do not match the extensive use of alcohol among diverse populations and age groups. Alcohol consumption spans many demographics, making it a common choice for individuals from adolescence through adulthood and into older age.
