“…The capacity of psychedelics and nature contact to increase a sense of connectedness is notable, as a sense of ‘disconnection’, alienation or isolation has been implicated with a broad range of mental illnesses including eating disorders ( Huemer et al, 2011 ), bipolar personality disorder ( Kverme et al, 2019 ), PTSD ( McDermott et al, 2012 ) and depression ( Karp, 2017 ; Sorajjakool et al, 2008 ; Watts et al, 2017 ). Interestingly, feelings of disconnection from nature and other humans are not uncommon insights described by psychedelic users (St John, 2018 ), and this disconnection is frequently viewed as a source of health and societal problems, with these substances perceived to partly facilitate healing by amending this disconnection ( Fotiou, 2012 ; Gearin, 2015 , 2017 ; Schmid, 2013 ; St John, 2018 ; Watts et al, 2017 ; Winkelman, 2013 ). Connectedness is considered a key predictor and mediator of well-being ( Capaldi et al, 2015 ; Cervinka et al, 2012 ; Lee et al, 2008 ; Saeri et al, 2018 ; Zelenski and Nisbet, 2014 ), in addition to a factor linked to recovery of mental health, including recovery from depression and addiction ( Drake and Whitley, 2014 ; Leamy et al, 2011 ).…”
