Cyclists often take cortisones when they're injured and they often use tramadol in the final of bike races to reduce pain (and thus ride harder). It's incredibly dangerous to use a drug like tramadol in a peloton of 200 cyclists driving at 50km/h. Tramadol slows your reaction time and makes it hard to concentrate. And it's not even illegal as of now! It has been linked with many crashes in the peloton.
Probably a lot of cortisone abusers in American sports. Some of those are very physical and injury prone.
