 Copped is a serious health condition caused primarily by smoking. It is characterized by reduced lung function and difficulty breathing. Early detection of copped is important because it allows for earlier intervention and treatment. This study found that certain measures of lung function, such as maximum mid-expiatory flow rate, could be used to identify smokers who are at risk of developing copped.
