Researchers have noted the relationship between psychedelics and ecology, particularly in relation to the altered states of consciousness (ASC) produced by psychedelic drugs and the perception of interconnectedness expressed through ecological ideas and themes produced by the psychedelic experience. This is felt through the direct experience of the unity of nature and the environment of which the individual is no longer perceived as separate but intimately connected and embedded inside.[1]
Swiss chemist Albert Hofmann, the first person to synthesize LSD, believed that the drug made one aware and sensitive to "the magnificence of nature and of the animal and plant kingdom" and the role of humanity in relation to nature.[2] Stanley Krippner and David Luke have speculated that "the consumption of psychedelic substances leads to an increased concern for nature and ecological issues".[3] As a result, American psychologist Ralph Metzner and several others have argued that psychedelic drug use was the impetus for the modern ecology movement in the late 1960s.[1]
