If by intense you mean guys taking balls and throwing them at a competitor, then they should not be illegal. While you guys are thinking about the potential earning of a doctor, think of the damage and immorality it can bring out in a person. "Roid rage" is fairly common with those who consume them.Steroids should be legal. The fact that they're illegal now doesn't stop people from using them, but legalising them could help prevent some of their major side effects since you can tell your doctor you're on them and he can monitor your health. Plus imagine how intense all of the sports will get with a little bit of boost.
I find it disgusting that you guys are even talking about the idea of legalizing them.
