Athletes since the beginning of time have looked into gaining an advantage on their opponents in order for them to succeed and excel in their sport.  In my personal opinion using a substance that will give you an advantage over another person is cheating. Different leagues use different systems to punish those who are caught using PED’s (performance enhancing drugs), but unfortunately those who violate the rules sometimes come back and violate the rules again. In my opinion every pro sport should use the lifetime ban. If you’re caught once then you should be kicked out for life. Pete Rose who is the all-time hits leader in the MLB was kicked out for life for gambling and sense then no one else has been caught gambling. This should be implemented with those who cheat in general.
