A photograph of an unnamed boy in a cage features in Sean O’Carroll’s exhibition about Ritalin.

A BOY crouches naked in a steel animal cage, with the downcast eyes of a prisoner.

This confronting image, meant to represent a ”chemical cage” of drugs to treat attention deficit hyperactivity disorder, is part of an exhibition called Ritalin by photographer Sean O’Carroll.

O’Carroll, a former teacher, said the exhibition expressed his concern about the widespread administering of what he called addictive mind-altering drugs to young boys, which was ”a catastrophic failure on the part of our society to deal with the challenge of raising active, energetic and ‘difficult’ boys”.
