Performance-enhancing substances can be harmful to adolescents, survey of pediatricians says

Researchers say pediatricians, family doctors and parents need to learn more about what kind of performance-enhancing substances kids are using when they work out or play sports.

Seventeen per cent of more than 800 Canadian pediatric specialists surveyed said they saw adolescents who needed medical attention due to performance-enhancing products, including both legal and illegal substances, during the previous year.
