Simon maintains that the strongest grounds for banning performance enhancing drugs is
  based on
 
  a. applying current drug laws to everyone equally, and not making an exception for
  athletes.
  b. the fact that athletes are widely admired by children, and the use of drugs by athletes
  is likely to cause harmful drug-abuse behavior in impressionable children.
  c. the ideals of athletic competition.
  d. the serious long-term physical and psychological harm caused by the use of such
  drugs.
  e. recognition of the fact that high-level athletic competition is at most only one brief
  phase of an individual's life, but harms from drug use are often permanent.
