Doping drugs as we all know are banned drugs which enhance performance of sports persons and athletes. They range from steroids to newer synthetic drugs. Stimulants, Steroids, Diuretics (often used to lower the body weight) and artificial Hormones, growth Hormones, Narcotic Analgesics are all considered as doping drugs.

For a more elaborate explanation go through this website:

As we have done two separate investigations on mice, oxymetholone and stanozolol induced severe damages in testicular tissue and embrytoxicities. Upon my incomplete knowledge, anabolic-androgenic steroids (AASs) induce hypogonadotrophic hypogonadism via negative feedback to the hypothalamus leading to testicular atrophy and impaired spermatogenesis. Despite therapeutic significance (treatment of anemias or therapy of myelotoxic anticancer drugs-induced myelofibrosis and AIDS-associated wasting ), AASs causes hepatic and cardiac damages too. Unfortunately, According to statistics of the International Olympic Committee, over half of positive doping cases are due to AASs abuse. For more precise information please find the attached.

At first, I want to say 'Thank you', Prof. Dr. Pravin Tirgar, for this great question.

Let me start by this: (Taking and Giving) Drugs in sports fields have a lot of side effects which can effects athletes physically and mentally.

On Physical side I can cite what the great editor John O’Leary in his book named: (Drugs and Doping in Sport Social-Legal Perspectives) has said:

“There is no doubt that doping can damage your health. Anabolic agents such as Stanozolol and testosterone increase strength and endurance but can lead to aggressive behaviour, impotence, Kidney damage and breast development in men, and the development of male features, facial and body hair in women. Beta blockers reduce heart rate and blood pressure, but can lead to dangerously low blood pressure. Blood doping where blood is taken from the athlete's body re-oxygenated and then pumped back into the athlete can lead to allergic conditions, blood clotting and kidney damage. Diuretics such as frusemide and triameterine encourage weight loss, but cause nausea, cramps and dehydration. Stimulants such as amphetamine increase mental and physical stimulation, but raise blood pressure and make the heartbeat irregular. The much-publicised EPO aids pain control and muscle growth, but can cause abnormal growth of internal organs and increase the risk of blood clots and strokes. Human growth hormone in adults increase the number of red blood cells, boosts heart function and makes more energy available by stimulating the breakdown of fat. However, inflated levels of human growth hormone can cause acromegaly, a disease characterised by excessive growth of the head, feet and hands. The lips, nose, tongue, jaw and forehead increase in size and the fingers and toes widen and become spade-like. The organs and digestive system may also increase in size, which may eventually cause heart failure".

From legal side I can speak, and I provide examples with evidence about the size of the Real damages employing drugs' in sports could does, examples:

1. Case No1: Greg Titus who was on Steroids' use, and his wife Kelly Ryan are killing their friend (Melissa James), on December 13 or 14, 2005.

2. Case No2: Mike Tyson bites Evander Holyfield's ear. On June 28, 1997, Mike Tyson bites Evander Holyfield's ear in the third round of their heavyweight rematch. The attack led to his disqualification from the match and suspension from boxing, and was the strangest chapter yet in the champion's roller-coaster career.

And the list is the longest.
