One thing that is troubling about performance-enhancing drugs is the increased probability of addiction to other substances. Several studies have shown an increased misuse of other drugs by those who use PEDs. For example a study reported in the journal Drug and Alcohol Dependence showed that athletes who use steroids are at a greater risk of opioid analgesic misuse. These drugs include codeine, oxycodone, fentanyl, hydrocodone and hydromorphine. Another study in the journal Drug and Alcohol Dependence showed that men with an anabolic steroid dependence showed a pattern of concurring opioid (painkiller) dependence. In addition Drug and Alcohol Dependence cited a study showing that the use of anabolic steroids is associated with the use of alcohol and illicit drug use.
If you’re still struggling to imagine that, lets use a more realistic example. Take the “blade runner,” Oscar Pistorius, for example. Respectfully ignoring recent events, he was a fantastic athlete, but he would not have been had it not been for his carbon-fiber, prosthetic “cheetah-style” legs. He was so good he even competed in the Olympics against fully able-bodied athletes. But this begs the question: what if one day somebody created an artificial limb that made the wearer run much faster than the human leg would normally allow?
