You can get somewhat faster results using steroids (provided you are a decent responder and don't experience strong sides), sure. However, the overwhelming majority of people complaining about (often hypothetical) drug users are not putting in even minimal effort and haven't taken the time to learn how to train properly. I'm unconvinced that this is anything but a way to protect their ego and simultaneously feel cheated of the god-like bodies they would most assuredly have if it wasn't for their superior morals and judgement. It comes as no surprise that those very people don't get anywhere once they hop on gear, which is something I've witnessed firsthand a few times.
