Steroids themselves aren't an addiction, nor do I think they're "cheating" in most high-level sports, not anymore. No one these days plays without some form of enhancement, legal or otherwise. To be sucessful at the top echelon of almost any sport, you do what it takes to keep up. As far as addiction... they aren't physically addictive in and of themselves. However, people can certainly become psychologically addicted to the pumps, the size gains, the strength, how they look, etc. That's why some guys start off with a 10 week cycle and end up staying on for 2 years. Do I think they're addictive? No. Do I think they can still be abused? Hell yes.
