To the Editor.— As a high school teacher I have been looking for guidance on preventing the abuse of anabolic steroids by our students. The article "Anabolic Steroid Use by Male Adolescents" by Johnson et al1 not only failed to provide this guidance, but the results failed to support the authors' conclusions. The study shows that, of the teenage users of steroids surveyed, 38% correctly identified liver disease, 35% cancer of the liver, and 30% stunted growth as side effects of steroid use.
