When most organized sports had already implemented drug policies, the history of steroids in baseball is relatively recent. In fact, in the United States, major league baseball was the last sport to adopt a policy dealing with drugs. Steroids in baseball is an ongoing issue since it is still fairly new, but the beginning of the steroids in baseball saga is often attributed to Mark McGuire and a bottle of performance enhancers found in his locker.
The story of steroids in baseball continued from there including various players admitting they used steroids. Other reports included players stating that they knew that a fairly large percentage (varying from 50-85%) of players used or have used steroids in baseball. It was probably at this point that the media really picked up on steroid use and steroids in baseball became a major issue.
Another issue related to steroids in baseball is that players say that had used steroids in the past but that they didn't know they were steroids – instead, trainers were giving them creams and pills under the guise that they were other treatments. During the time of this alleged use, however, the league had not yet outlawed steroids in baseball.
These reports of steroids in baseball did draw major media attention, however and many people think that these reports of steroids in baseball may have hurt the sports as a league. People wonder if records would have been broken if it hadn't been for steroids in baseball. There is also speculation that the popularity of the sport has declined due to the media surrounding steroids in baseball. Other sources say, however, that the sales and overall popularity of the sport has not declined during the steroids in baseball mess.
Even with drug testing and rules and regulations against steroids in baseball, most people will agree that players and trainers are able to supersede these tests to help the players enhance their performance and continue to break records. Because of this, the story of steroids in baseball is not over.
