Effects of Performance-Enhancing Drugs
With all the information, attention, and debate over performance-enhancing drugs (or PEDs), many people want to further understand how performance-enhancing drugs affect one’s body. It’s an important area of concern for athletes and at the foundation of why USADA and other anti-doping organizations exist. Simply put, PEDs have the ability or potential to drastically alter the human body and biological functions, including the ability to considerably improve athletic performance in certain instances. These drugs, however, can be extremely dangerous and, in certain situations, deadly. The negative effects these drugs can have on one’s body make USADA’s mission paramount as to why no athlete should ever have to consider PED use to succeed in sport.
This section provides answers to common questions about the health and safety risks associated with substances and methods on the WADA Prohibited List (List). It also provides information concerning the legitimate medical use of substances. When these compounds are misused, it constitutes a breach of ethics both by the user and supplier.
Anabolic Agents (Including Testosterone)
The primary medical use of these compounds is to treat delayed puberty, some types of impotence, and wasting of the body caused by HIV infection or other muscle-wasting diseases. What are some potential side effects of anabolic steroid abuse? Some physiological and psychological side effects of anabolic steroid abuse have potential to impact any user, while other side effects are gender specific. The following list is not comprehensive.
Gender Specific – Males
Gender Specific – Females
NOTE: * Effects may be permanent and can vary by individual.
Peptide Hormones, Growth Factors, and Related Substances
The primary medical use of these compounds vary, but include treatment of cancer or aiding those born prematurely. The presence of an abnormal concentration of a hormone, its metabolites, relevant ratios or markers in your sample is deemed to contain a prohibited substance unless you can demonstrate the concentration was due to a physiological or pathological condition. Examples include human growth hormone (hGH), erythropoietin (EPO), insulin, human chorionic gonadotrophin (HCG), and adrenocorticotrophin (ACTH). Despite the presence of some growth factors, platelet-derived preparations were removed from the List as current studies on PRP do not demonstrate any potential for performance enhancement beyond a potential therapeutic effect.
Note that individual growth factors are still prohibited when given separately as purified substances as described in S.2.5.
Human Growth Hormone (hGH) Physiological
The primary medical use of these compounds is to treat conditions such as asthma and other respiratory ailments. Some studies have shown beta-2 agonists have performance-enhancing effects when consistently high levels are present in the blood.
The primary medical use of these compounds is to treat conditions such as hypertension, kidney disease and congestive heart failure. Taken without medical supervision, diuretics can result in potassium depletion and possibly even death.
The primary medical use of these compounds is to treat conditions such as Attention Deficit Disorders (ADD/ADHD), asthma, narcolepsy, and obesity.
Marijuana is classified by Congress as a Schedule 1 drug under the Controlled Substances Act (CSA). This means that it has a high potential for abuse, no accepted medical use in the United States, and lacks accepted safety data for use under medical supervision. Side effects of cannabinoid use include:
Blood doping is the practice of misusing certain techniques and substances to increase the red blood cell mass in the body. Since the red blood cells carry oxygen to the muscles, this allows the body to transport more oxygen to working muscles and therefore can increase their aerobic capacity and endurance. There are three widely known substances or methods used for blood doping, namely, erythropoietin (EPO), synthetic oxygen carriers and blood transfusions*. The primary use of blood transfusions and synthetic oxygen carriers are for patients who have suffered massive blood loss, either during a major surgical procedure or caused by major trauma. Erythropoietin is used in the treatment of anemia related to kidney disease. However, misuse of these substances and techniques could lead to:
*With transfusions, there is an increased risk of infectious disease such as AIDS or hepatitis.
In small doses narcotics have medical uses that include relieving severe pain and inducing sleep. However, narcotic overdose is a medical emergency and can lead to respiratory depression and even death.
While a sensation of euphoria and psychological stimulation are effects common to the use of narcotics, the misuse of narcotics can pose ethical questions about the handling of the substance as well as great health risks. Those include:
The primary medical use of beta-blockers is to control hypertension, cardiac arrhythmias, angina pectoris (severe chest pain), migraine, and nervous or anxiety-related conditions.
The primary medical use of these compounds is to treat allergies, asthma, inflammatory conditions, and skin disorders among other ailments.
