There is much debate about how much effect steroid use has on the premature deaths of professional wrestlers. As this list will be updated with causes of death, where available, it is beneficial to have some idea of the side effects of steroid use. While the true long term side effects are not fully known, it is believed that just a few of the side effects of steroid use include: heart disease, liver damage, kidney damage, cancer, strokes and blood clots, depression, thoughts of suicide, paranoia, hallucinations, severe mood swings, and ‘roid rage’ – severe, agressive behavior that may result in violence.
WWE helped promote it through an on-screen angle (a fictional storyline used in wrestling). This involved the heel Chris Jericho criticizing legendary retired wrestlers such as Ric Flair , who he felt were embarrassing themselves, as well as Mickey Rourke for his portrayal in The Wrestler . At the 15th Screen Actors Guild Awards , Rourke announced he would be competing at WrestleMania XXV , specifically targeting Jericho.  The announcement led to a confrontation between the two on Larry King Live , which showed signs of second thoughts from Rourke.  On January 28, it was announced through Rourke's spokesperson that the actor would not compete at the event,  and he was soon after announced instead as a guest.
