What is the most widely-consumed drug in western society?

Caffeine is widely considered the most consumed psychoactive substance in Western society. It is a central nervous system stimulant found in various beverages, such as coffee, tea, and energy drinks, which are integral to daily routines for many individuals. The prevalence of caffeine consumption can be attributed to its ability to enhance alertness and combat fatigue, making it a popular choice among people working in various sectors.

In contrast with other substances listed, caffeine is typically consumed in social, familial, and professional settings, which further contributes to its widespread use. While alcohol and tobacco are also highly prevalent, the daily consumption of caffeine in various forms often surpasses that of these substances. Marijuana has gained acceptance in many areas and has seen increased usage, but its overall prevalence still lags behind caffeine when you consider daily consumption levels across the population.
