Luke Combs says he has a type of obsessive-compulsive disorder known as 'pure O,' an unofficial diagnosis where the compulsions are entirely mental.

Country superstar Luke Combs opened up about his experience living with purely obsessional obsessive-compulsive disorder, informally known as Pure O, in a recent interview with 60 Minutes Australia.
