Is it true that some animals, like humans, are prone to intoxication, drugs and poisonous substances? Such natural phenomena, it turns out, are directly related to the ability of animals to immobilize their victim or enemy with the help of their body products, as well as to overcoming pain and to many features of animal behavior. It is interesting about these curious things, the author, Doctor of Biological Sciences Sergei Aleksandrovich Korytin, known for his work on animal ethology and zoopsychology, tells with a kind smile. It is proposed to consider the origins of alcoholism, drug addiction in humans and similar manifestations in animals in a new concept for the study of these bad addictions.
