However, there is a high number of cases when this knowledge does not make people break the habit. One more controversial question is caffeine addiction influence a personality. Considering this question one can notice that there are different views on the phenomenon of caffeine addiction. Some researchers claim that it is, but other tells that habit to use caffeine does not become an addiction. Finding compromise one can say that in any case, overindulgence of any product can lead to negative consequences, and caffeine is not an exception, whatever is its overindulgence named addition or not.

Considering the issue of caffeine addiction, one can notice that even though the first association with this issue will be coffee, there is a wide amount of products that contain caffeine. Joseph notices that there are more than sixty plant products, including tea, coffee and kola nuts that hold caffeine. Crocq saw that “approximately 80% of the inhabitants of affluent countries drink coffee or tea daily” (182). Considering the reasons for such popularity Crocq wrote that “subjectively, caffeine increases feelings of well-being, a motivation for work, and desire to socialize” (182). Considering the effect of caffeine more detailed, on a biological level, Joseph refers to Groves and Rebec claiming that caffeine “stimulates the heart and increases tension in the skeletal muscles while relaxing the respiratory smooth muscle.” Joseph also describes the two main ways in which caffeine acts: it “stimulating cellular metabolism and mimicking neurotransmitters to stimulate the brain and nervous system.” Considering the data about caffeine effect and subjective perception of it one can say that it seems to be quite positive.
Some sources confirm the positive effect of caffeine. Crocq already cited above noticed that caffeine “induces alertness, elevates mood, and facilitates ideation” (182). Smith also notices that caffeine have some beneficial effects that “can be most easily demonstrated in low arousal situations” and that “improved performance has been shown when reduced alertness is not involved” (1250). Smith also noticed “caffeine improves the performance of artificial tasks and simulations of driving and industrial work” that allows suggesting that “it will be of benefit in safety-critical situations and will improve operational efficiency” (1250). Hale is one more researcher who noticed the positive effects of caffeine. The researcher noticed that brain processes that have been shown “to benefit from caffeine include selective visual attention, task switching, conflict monitoring, and response inhibition” (Hale). Hale also wrote that caffeine positively influences sustained attention and selective attention.
