In his book, Nutt tried to answer in simple terms the countless questions associated with the symbiosis of man and ethanol going into the darkness of centuries. Why is alcohol a drug? How does it affect our psyche? How to avoid a hangover? Why does the liver suffer especially from drunkenness? What are the social benefits of drinking? How do you know if you're addicted? Are there successful alcoholics? What strategies help control alcohol use? Is the alcoholic guilty of his condition? How do different drugs for the treatment of alcohol dependence work? What should governments do about this? All this information, supported by the latest scientific data, should help each of us determine for ourselves that ideal dose of alcohol that will bring maximum joy with minimal harm - and ultimately answer the eternal question "To drink or not to drink?".
