I’ve thought about this a lot and I’ve gone back to being against it. A lot of performance enhancing drugs push your cardiovascular system pretty hard. If everyone is trying to juice as much as possible to win, they’ll end up competing to getting as close to death as possible for our entertainment to achieve the max performance. They’re either killing themselves in the process or shaving decades off their natural lifespans. I don’t know if creating such a system would be ethical.
