When Michael Pollan was preparing to investigate the use of drugs in the treatment of depression, addiction and anxiety, which are so difficult to overcome, he did not intend at all to create what happened - the most personal of his books. But finding that these substances can improve the quality of life of not only mentally ill, but also quite healthy people, barely restraining pressure from everyday life, he decided to determine the topography of his own consciousness and wrote a lot in the first person. Thus began his journey through various altered states, during which he addresses advances in brain science. Pollan also did a lot of work in the archives to separate the truth about psychedelics from the common myths that have dominated ideas about them since the 1960s, when negative attitudes towards what had potential for science were lobbied.
