Anti-Doping in Sport: WADA, NADA, CAS and the Code
Exam notes on anti-doping in sport: WADA and its Code, the Prohibited List, NADA and the NDTL in India, the 2022 Act, and the Court of Arbitration for Sport.
By GK24 Editorial Team· Published · 4 min read

Doping means the use of a banned substance or method to improve sporting performance, and the system built to stop it has its own agencies, its own rule book and its own court. The modern structure dates from the Festina affair of the 1998 Tour de France, when a team car full of banned drugs forced governments and the Olympic movement to act together. The World Anti-Doping Agency was created the next year as the result. For an examiner the topic is a gift, because it has crisp, unchanging facts: a founding year, a headquarters city, a rule book, a laboratory and a court.
The World Anti-Doping Agency
- WADA was established on 10 November 1999 and its headquarters is at Montreal in Canada, with regional offices elsewhere; Lausanne in Switzerland houses its European office.
- It is a foundation under Swiss law and is funded half by the Olympic movement and half by the governments of the world, which gives both sides equal seats on its board.
- Its slogan is Play True, and it runs education, research, testing standards and the accreditation of laboratories.
- The World Anti-Doping Code is the single document that harmonises anti-doping rules across sports and countries. It first came into force on 1 January 2004 and has been revised more than once, the 2021 version among them.
- The Prohibited List is issued by WADA every year and takes effect on 1 January.
The Prohibited List and the key ideas
| Idea | What it means |
|---|---|
| Substances banned at all times | Anabolic agents, peptide hormones and growth factors, beta-2 agonists, hormone and metabolic modulators, diuretics and masking agents |
| Substances banned in competition only | Stimulants, narcotics, cannabinoids and glucocorticoids |
| Banned in particular sports | Beta-blockers, in sports such as archery and shooting where a steady hand matters |
| Prohibited methods | Manipulation of blood and blood components, chemical and physical manipulation of a sample, and gene and cell doping |
| Strict liability | An athlete is responsible for whatever is found in the body, whether or not it was taken on purpose |
| Therapeutic Use Exemption | Written permission to use a banned medicine for a genuine illness, granted in advance |
| Whereabouts rule | Athletes in the registered testing pool must file where they can be found, so that out-of-competition testing is possible without notice |
| Athlete Biological Passport | A record of an athlete's own blood and steroid values over time; a sudden change is itself evidence of doping |
A urine sample is split into an A sample and a B sample. The B sample is opened only if the A sample tests positive and the athlete asks for it, so that the finding can be confirmed. Erythropoietin, known as EPO, raises the red blood cell count and thus the oxygen carried to the muscles, while anabolic steroids build muscle and shorten recovery; blood transfusion of one's own stored blood is the method called blood doping.
Anti-doping in India
- The National Anti-Doping Agency, NADA, was set up on 24 November 2005 as a registered society under the Ministry of Youth Affairs and Sports, and it plans and carries out testing, results management and education in India.
- The National Dope Testing Laboratory at New Delhi is the country's testing laboratory and works under the same ministry; its accreditation comes from WADA.
- India is a party to the International Convention against Doping in Sport, adopted under the auspices of UNESCO in 2005, which is the treaty through which governments bind themselves to the Code.
- The National Anti-Doping Act, 2022 gave statutory backing to the system: it provides for the National Anti-Doping Agency and the National Dope Testing Laboratory in law and sets up a National Board for Anti-Doping in Sports to oversee the agency's work.
- Inside NADA, an Anti-Doping Disciplinary Panel hears a case first and an Anti-Doping Appeal Panel hears the appeal.
The Court of Arbitration for Sport
- CAS was established in 1984 on the initiative of the International Olympic Committee and sits at Lausanne in Switzerland, with branches at Sydney and New York.
- Since the Paris Agreement of 1994 it has been run by the International Council of Arbitration for Sport, which keeps it independent of the Olympic committee that founded it.
- It has an Ordinary Arbitration Division for contract disputes, an Appeals Arbitration Division for appeals against the decisions of sports bodies, and an Anti-Doping Division that hears doping cases at first instance for those who have accepted its authority.
- Ad hoc divisions have sat at the Olympic Games since the Atlanta Games of 1996 so that disputes during the Games are settled within days.
- An award of CAS may be challenged only before the Swiss Federal Tribunal, and only on narrow grounds, which makes CAS in practice the last word in world sport.
Cases that papers mention
- Ben Johnson of Canada was stripped of the 100 metres gold medal of the 1988 Seoul Olympics after testing positive for the anabolic steroid stanozolol, the case that made doping a public issue.
- Lance Armstrong of the United States lost his seven Tour de France titles of 1999 to 2005 after a long investigation by the United States Anti-Doping Agency.
- Maria Sharapova of Russia was suspended in 2016 for meldonium, a substance that had been added to the Prohibited List at the start of that year, a reminder that the list changes each January.
Exam Point of View
Most questions are single facts: the year WADA was founded, the city of its headquarters, its slogan, the year the Code came into force, the year NADA was set up and the ministry it works under, the city of the National Dope Testing Laboratory, the body under which the 2005 convention was adopted, and the seat and founding year of the Court of Arbitration for Sport. A second group tests the vocabulary: what a Therapeutic Use Exemption is, what strict liability means, why there is an A sample and a B sample, what the whereabouts rule requires and what the Athlete Biological Passport records. A third group asks which class of substance is banned only in competition, with stimulants and narcotics as the answer, and which class is banned only in particular sports, which is beta-blockers in shooting and archery. The usual traps are placing WADA at Lausanne instead of Montreal, confusing WADA with NADA, dating the Code to 1999, and thinking an appeal from CAS goes to the International Olympic Committee rather than to the Swiss Federal Tribunal.

Practice MCQs on this topic
Where is the headquarters of the World Anti-Doping Agency (WADA)?
- A.Lausanne, Switzerland
- B.Montreal, Canada
- C.Paris, France
- D.New York, United States
Show answer
Explanation
The correct answer is B, Montreal, Canada. WADA began work in 1999 from Lausanne and then moved its headquarters to Montreal, where the agency has remained; Lausanne continues as its European office. Option A is wrong, and it is the trap in this question, because Lausanne is the seat of the International Olympic Committee and of the Court of Arbitration for Sport, so candidates place every sports body there. Option C is wrong because Paris is the headquarters of UNESCO, which adopted the International Convention against Doping in Sport in 2005, and of the International Council of Sport Science and Physical Education, not of WADA. Option D is wrong because New York holds the United Nations headquarters and a branch office of the Court of Arbitration for Sport, but no office of WADA of that standing. Remembering the pair Montreal for WADA and Lausanne for the Olympic bodies settles a whole family of questions.
In which year was the World Anti-Doping Agency established?
- A.1984
- B.1994
- C.1999
- D.2004
Show answer
Explanation
The correct answer is C, 1999. WADA was created on 10 November 1999, a year after the Festina affair of the 1998 Tour de France, in which a team car carrying banned drugs exposed how organised doping had become and pushed the Olympic movement and governments to build a joint agency. Option A is wrong because 1984 is the year the Court of Arbitration for Sport was established on the initiative of the International Olympic Committee. Option B is wrong because 1994 is the year of the Paris Agreement, by which the International Council of Arbitration for Sport was created to run that court independently. Option D is wrong because 2004 is the year the World Anti-Doping Code came into force, on 1 January, five years after the agency itself. Holding the sequence 1984 for the court, 1994 for its council, 1999 for WADA and 2004 for the Code answers four questions at once.
India's National Anti-Doping Agency (NADA) works under which ministry?
- A.Ministry of Health and Family Welfare
- B.Ministry of Youth Affairs and Sports
- C.Ministry of Home Affairs
- D.Ministry of Education
Show answer
Explanation
The correct answer is B, the Ministry of Youth Affairs and Sports. NADA was set up on 24 November 2005 as a registered society under that ministry, and it plans and carries out sample collection, manages results and runs education programmes so that sport in India is practised without doping. The National Anti-Doping Act, 2022 later gave the agency a footing in law and created a National Board for Anti-Doping in Sports to oversee it. Option A is wrong because the health ministry deals with drug regulation and public health, not with sport testing, although doping involves medicines. Option C is wrong because the home ministry has no role of this kind; narcotics control is a separate subject from sports doping. Option D is wrong because the education ministry handles school and higher education, while sport, including the Sports Authority of India and Khelo India, sits with the youth affairs and sports ministry.
The Court of Arbitration for Sport (CAS) has its seat in which city?
- A.Lausanne
- B.Geneva
- C.The Hague
- D.Monaco
Show answer
Explanation
The correct answer is A, Lausanne, in Switzerland. CAS was established in 1984 at the initiative of the International Olympic Committee, whose own headquarters is in the same city, and it also keeps branch offices at Sydney and New York besides sitting in ad hoc divisions at the Olympic Games. Option B is wrong because Geneva hosts the United Nations European headquarters, the World Health Organization and the World Trade Organization, but not this court. Option C is wrong because The Hague is the seat of the International Court of Justice, the International Criminal Court and the Permanent Court of Arbitration, which are courts between states, not between athletes and federations. Option D is wrong because Monaco is the headquarters of World Athletics, the governing body of track and field, which is a federation and not a tribunal. Appeals from a CAS award lie only to the Swiss Federal Tribunal.
The International Convention against Doping in Sport, the treaty by which governments bind themselves to the World Anti-Doping Code, was adopted in 2005 under the auspices of
- A.The World Health Organization
- B.The International Olympic Committee
- C.UNESCO
- D.The Commonwealth Games Federation
Show answer
Explanation
The correct answer is C, UNESCO. Because WADA is a private foundation, governments needed an instrument of international law through which they could commit themselves to the Code, and the United Nations Educational, Scientific and Cultural Organization provided it by adopting the International Convention against Doping in Sport in 2005. It is the treaty that most countries, India among them, have ratified. Option A is wrong because the World Health Organization deals with health standards and medicines but is not the parent of this convention. Option B is wrong because the International Olympic Committee is a private body and cannot make a treaty; it enforces the Code through the conditions of entry to the Games instead. Option D is wrong because the Commonwealth Games Federation only organises its own Games and, like other federations, is a signatory to the Code rather than the author of a convention.
Which of the following classes of substances is prohibited only in competition?
- A.Anabolic agents
- B.Peptide hormones and growth factors
- C.Stimulants and narcotics
- D.Diuretics and masking agents
Show answer
Explanation
The correct answer is C, stimulants and narcotics. The Prohibited List divides substances into those banned at all times, those banned only in competition and those banned only in particular sports. Stimulants, narcotics, cannabinoids and glucocorticoids fall in the in-competition group, because their effect is felt on the day of the event rather than through training. Option A is wrong because anabolic agents, which build muscle during training, are banned at all times, in and out of competition. Option B is wrong because peptide hormones and growth factors, among them erythropoietin and growth hormone, are likewise banned at all times. Option D is wrong because diuretics and masking agents are banned at all times, since their purpose is to flush or hide the traces of other drugs. Beta-blockers are the class banned only in particular sports, such as archery and shooting, where a slow heartbeat steadies the aim.
In anti-doping rules, what is a Therapeutic Use Exemption (TUE)?
- A.A reduced period of suspension for a first offence
- B.Advance permission to use a prohibited substance needed to treat a genuine illness
- C.Permission to miss an out-of-competition test while travelling
- D.A waiver of the fee for testing the B sample
Show answer
Explanation
The correct answer is B. An athlete who genuinely needs a medicine that appears on the Prohibited List, such as an inhaler for asthma or insulin for diabetes, applies in advance to a panel of doctors, which may grant a Therapeutic Use Exemption limited to that substance, dose and period. Without it the same medicine would be an anti-doping rule violation, because the principle of strict liability makes an athlete answerable for whatever is found in the body. Option A is wrong because a reduction of a sanction turns on matters such as the substance being a specified one, prompt admission or substantial assistance, not on a TUE. Option C is wrong because missing tests is governed by the whereabouts rules, and three failures in a year are themselves a violation. Option D is wrong because the testing of the B sample is a procedural right and has nothing to do with an exemption.
The National Dope Testing Laboratory of India is located at
- A.Patiala
- B.New Delhi
- C.Bengaluru
- D.Kolkata
Show answer
Explanation
The correct answer is B, New Delhi. The National Dope Testing Laboratory, which analyses the samples that NADA collects, functions at New Delhi under the Ministry of Youth Affairs and Sports, and its standing as a testing laboratory rests on accreditation by WADA. The National Anti-Doping Act, 2022 gives it a place in law as the principal dope testing laboratory of the country. Option A is wrong because Patiala is the home of the Netaji Subhas National Institute of Sports, the main coaching institute, which trains coaches rather than testing samples. Option C is wrong because Bengaluru has the Sports Authority of India centre at Kanteerava Stadium and many sports science facilities but not this laboratory. Option D is wrong because Kolkata, for all its sporting history, has no national dope testing laboratory. Keeping the pair Patiala for coaching and New Delhi for testing apart is the useful habit here.
What is the slogan of the World Anti-Doping Agency?
- A.Play True
- B.Faster, Higher, Stronger
- C.Sport for All
- D.Clean and Fair
Show answer
Explanation
The correct answer is A, Play True. The phrase has been WADA's slogan since its early years and appears on its campaigns, its outreach programmes at major Games and its education material for athletes. Option B is wrong because faster, higher, stronger is the Olympic motto, in Latin Citius, Altius, Fortius, to which the word together was added in 2021; it belongs to the International Olympic Committee and not to WADA. Option C is wrong because sport for all is a general movement for mass participation promoted by many governments and federations, not an anti-doping slogan. Option D is wrong because, although it sounds plausible and clean sport is an expression WADA uses, the slogan asked for in papers is Play True. Questions of this kind usually sit beside the Olympic motto, so the two should be learnt as a pair and kept distinct.
Which sprinter was stripped of the 100 metres gold medal of the 1988 Seoul Olympics after testing positive for the anabolic steroid stanozolol?
- A.Carl Lewis
- B.Ben Johnson
- C.Linford Christie
- D.Maurice Greene
Show answer
Explanation
The correct answer is B, Ben Johnson of Canada, who won the final in a world record time and lost the medal within days when his sample showed stanozolol. The case is treated as the moment doping became a public issue and is the usual example in questions on the subject. Option A is wrong because Carl Lewis of the United States finished second and was awarded the gold medal after the disqualification, so he is the beneficiary rather than the offender in this story. Option C is wrong because Linford Christie of Great Britain was moved up to the silver medal in the same race; his later career had its own controversy, but not at Seoul in 1988. Option D is wrong because Maurice Greene belongs to a later generation of sprinters and competed from the middle of the nineteen nineties, well after these Games.
Erythropoietin, better known as EPO, is prohibited in sport because it
- A.Increases the red blood cells and so the oxygen carried to the muscles
- B.Masks the presence of other banned substances in urine
- C.Slows the heartbeat and steadies the hand
- D.Reduces body weight quickly before weighing in
Show answer
Explanation
The correct answer is A. Erythropoietin is a hormone that signals the bone marrow to make red blood cells; when it is injected, the blood carries more oxygen to the muscles and endurance rises, which is why it has been the drug of choice in cycling and distance events and why it is banned at all times as a peptide hormone. Option B is wrong because masking is the work of diuretics and other masking agents, which dilute or block the detection of a drug; EPO is taken for its own effect. Option C is wrong because slowing the heartbeat and steadying the hand describes beta-blockers, which is exactly why they are prohibited in sports such as archery and shooting. Option D is wrong because rapid loss of weight before a weigh-in is sought through diuretics, again a different class. The related method of storing and re-injecting one's own blood is called blood doping.
Frequently Asked Questions
Where is the headquarters of the World Anti-Doping Agency?
At Montreal in Canada. WADA was created on 10 November 1999 and its first office was at Lausanne in Switzerland, which still houses a European office, but the headquarters moved to Montreal. Placing WADA at Lausanne is the commonest error, because Lausanne is the seat of the International Olympic Committee and of the Court of Arbitration for Sport.
What is the difference between WADA and NADA?
WADA is the world body that writes the Code and the Prohibited List and accredits laboratories. NADA is India's National Anti-Doping Agency, set up in 2005 under the Ministry of Youth Affairs and Sports, which applies those rules within the country by collecting samples, managing results and running education programmes.
What is a Therapeutic Use Exemption?
It is written permission for an athlete to use a medicine that appears on the Prohibited List because a genuine illness requires it, for example an inhaler for asthma or insulin for diabetes. The application is decided in advance by a panel of doctors, and without it the same medicine would count as doping under the rule of strict liability.
Why is a dope sample divided into an A sample and a B sample?
The A sample is analysed first. If it shows a banned substance, the athlete may ask for the sealed B sample to be opened and tested, usually in the athlete's presence or that of a representative, so that the first finding can be confirmed independently. A charge normally proceeds only when the B sample agrees with the A sample.
Which court hears appeals in doping and other sports disputes?
The Court of Arbitration for Sport, established in 1984 and seated at Lausanne in Switzerland. It hears appeals against decisions of international federations and national bodies, runs an anti-doping division, and sits in ad hoc divisions at the Olympic Games. Its award can be challenged only before the Swiss Federal Tribunal.
What does the whereabouts rule mean for an athlete?
Athletes placed in a registered testing pool must inform the anti-doping authority where they will be, including a daily one-hour window and the address for it, so that samples can be collected out of competition without notice. Repeated failures to be available or to file the information are themselves an anti-doping rule violation.
