The second dimension of a cup of coffee is related to its use as a drug. Coffee contains caffeine, a drug that stimulates the brain. For many people, this is why they drink coffee. It is interesting in sociology why coffee addicts are not considered drug users in Western culture, although they may be in other cultures. Like alcohol, coffee is a socially acceptable drug, while marijuana is not. However, in other cultures, the use of marijuana is tolerable, but the consumption of coffee and alcohol is unpopular. However, the third dimension of a cup of coffee is closely related to social and economic relationships. The cultivation, packaging, distribution and marketing of coffee is a global enterprise that influences many cultures, social groups and organizations in these cultures. These things often happen thousands of miles from coffee drinkers. Many aspects of our lives are now in global trade and communications, and studying these global deals is very important to sociologists. Mills discussed another aspect of sociological imagination in his book. He values this most, and this is our future possibility. Sociology not only helps us analyze current and existing social life patterns, but also helps us see some possible futures open to us. Through sociological imagination, we can not only see what is real, but we can see that if we want to do so, then what can become a reality.
