The psychedelic experience also hinges on setting: who or what is or isn’t in our immediate surroundings; the environment we’re in, whether natural or urban, indoor or outdoor; the quality of the air and ambient sound around us; and so on. Setting also partakes of the set of who is with us while we take the drug, whether they be a friend or a stranger, relaxed or tense, a supportive guide or a probing scientist.
