I heard that MMA fighters take special painkillers so as not to feel bumps. Do you think these rumors are true?
MMA is the same sport as everyone else. Many drugs (like doping) cannot be used here. These rumors are caused by the fact that CBD oil is often used to aid in relaxation after training. This Site talks about it in detail. CBD oil helps athletes recover faster after heavy fighting. It is safe and doesn't even contain THC.
