Sportsmen who use performance enhancing drugs may suffer physical effects including liver and kidney damage, baldness, skin discolouration, testicular shrinkage, a higher voice, infertility and breast growth. Women however, may experience liver and kidney damage, deepening of the voice, breast reduction, menstrual cycle irregularities and facial hair growth. As well as these physical effects, men and women both can be subject to emotional distress, severe mood swings, hallucinations and violence on and off the field. Performance enhancing drugs, if taken by an adolescent, can cause long term health problems and stunt the person's further development. A recent study of high school students in America shows that statistics on students who used steroids rose from % of 40 kids to % of 40 kids in one year.
In most cases every drug under each category listed above can be obtained legally with a prescription, however most are illegal to use without a prescription and banned from use by most sporting associations. Depending on the organization in-which you compete the level of enforcement of the rule will vary but an interesting note, the majority of people who use performance enhancing drugs do not partake in any organized sporting competition but do so only to look better than they would otherwise. Unfortunately for these individuals, most of them do so by breaking the law but this legal factor does not seem to be slowing down the use by any means.
