Alcohol: No substance in the world seems so familiar to us and is so incredibly diverse in its effect. Alcohol is available everywhere and this particular molecule has the power to affect all 200 billion neurons of our human brain in completely different ways. But hardly anyone calls alcohol a drug despite its psychoactive and cell-destroying effect. Why do we tolerate the death of three million people every year? Have we turned a blind eye to the dangers and risks for thousands of years? What role does the powerful alcohol industry play with an annual turnover of 1.2 trillion euros in this on-going concealment? The author, who himself enjoys having a drink, looks into the question why we drink at all, what alcohol does to us and to what extent the alcohol industry influences society and politics.
