As a group they have a higher rate of substance abuse.<ref name = Breithenfeld/> The most common chemical substance which is abused by pop musicians is [[cocaine]],<ref name = Breithenfeld/> because of its neurological effects. Stimulants like cocaine increase alertness and cause feelings of [[euphoria]], and can therefore make the performer feel as though they in some ways 'own the stage'. One way in which substance abuse is harmful for a performer (musicians especially) is if the substance being abused is aspirated. The lungs are an important organ used by singers, and addiction to cigarettes may seriously harm the quality of their performance.<ref name = Breithenfeld/> Smoking harms the alveoli, which are responsible for absorbing oxygen.
