Don't single out cycling. Doping is rampant and risk free (when it comes to the risk of being caught) in every professional sport. They decided to do something about it in cycling while most sport federations (with maybe the exception of the UFC) prefer to turn a blind eye. There is much more incentive to dope in soccer, NFL, NBA or tennis and about zero risk of ever being caught if you're not a complete idiot about it. It's safe to say cycling is one of the cleanest sports now and wasn't the dirtiest in the past. Sure you still have compounds that are detectable for like 3-4 hours and you still have designer drugs which are not detectable yet but at least you have to deal with an organization willing to test and use biological passport while for example in soccer everyone works together so it's easy to dope and get those 100 high paced games per season done.
