Why is steroid use such a big issue?

I only trust people who admit they’re on steroids— openly.

Why are steroids such a big issue? I think the biggest issue is that they are dangerous, and also propagate false imagery for men, maybe even women. For example, I’m certain that a lot of these female CrossFit athletes, female powerlifters, female athletes, even Olympic athletes or sprinters are all taking some sort of steroids or weird performance enhancing drugs.
