In the present article we will try to answer to a cognitive dissonance on the effects of alcohol consumption. Namely, on one hand it is viewed by many people as an acceptable and beneficial thing, becoming increasingly popular among youngsters, while on the other hand both common sense and empirical data reveal a host of negative effects for both the consumer and the others. We will explore which of the two is supported by evidence and see how this habit reproduced and amplified by some wicked social environments come against the principle of negative (non-corruptive) education of J. J. Rousseau.
