6 types of drugs banned by the Olympics, and how they affect athletic performance, from marijuana to trimetazidine – Yahoo News

Olympic athletes are barred from using hundreds of different medications and drugs.
Many offer a potential advantage in endurance, muscle-building, energy, or focus.
The rules have prompted controversy around how athletes are penalized for testing positive.
Elite athletes competing at the Olympics and other international sporting events are banned from using certain medications and drugs, on the grounds that they may present safety risks, give unfair advantages, or violate the "spirit of sport," according to the World Anti-Doping Agency (WADA).
Recent controversies surrounding high-profile athletes like Sha'Carri Richardson and Kamila Valieva have called into question what should happen to athletes caught using banned substances, and why certain drugs are banned at all.
Hundreds of substances are on the banned list, with widely varied reasons for prohibiting them. Major categories of banned drugs, like stimulants, anabolic agents, and metabolic modulators can affect athletic performance by accelerating muscle gains, improving blood flow, and boosting endurance and focus.
Certain banned substances are designed to be used prior to competition, not during the event itself, to help athletes build muscle more quickly.
Known as training drugs, the category includes anabolic steroids, a wide range of synthetic forms of the human hormone testosterone that help prompt the body to pack on muscle to become bigger and stronger, according to the Mayo Clinic.
Growth factors, like human growth hormone (HGH), also aid in building muscle and connective tissue, like ligaments and tendons, and help protect them from breaking down during intense exercise.
Nigerian sprinter Blessing Okagbare was barred from the 2021 Toyko Olympics after testing positive for growth hormones.
Included in the same category as growth hormones are peptide hormones like erythropoietin, which help the body produce more red blood cells and more effectively oxygenate the muscles. By making more oxygen available, the drugs can help improve endurance.
Using peptide hormones for a competitive edge is known as "blood doping," Dr. Charles Yesalis, professor emeritus of health and sports science at Penn State, previously told Insider.
Another class of drugs called hormone and metabolic modulators can speed up or slow down certain chemical reactions in the body. They're considered performance-enhancing because they can help delay exhaustion for athletes in endurance sports or improve efficiency.
Trimetazidine, for instance, is a medication used to treat angina (chest pain from reduced blood flow), which works by making the heart more efficient without increasing heart rate or blood pressure. It's been involved in several Olympic controversies — most recently, 2022 Russian figure skater Kamila Valieva tested positive for trimetazidine, losing her chance at a medal despite being allowed to compete.
Stimulants include drugs and medications that ramp up energy and attention. They can benefit athletes by keeping athletes alert and focused during competition as well as improving blood flow and reaction time, according to the Mayo Clinic.
Illicit drugs, like cocaine and methamphetamine as well, as prescription drugs like Adderall (without a medical exemption) are included in the banned stimulant category.
Caffeine, the most popular performance-enhancing (and psychoactive) drug in the world , was also banned at the Olympics until 2004 for its stimulating effects, the Chicago Tribune reported.
Cannabis has been banned in the Olympics for two decades, along with any products containing its active ingredient, THC.
However, experts have called THC a "gray area" when it comes to performance enhancing drugs. The substance is primarily used to promote recovery and relieve pain, according to Yesalis.
Another component of cannabis called cannabidiol or CBD, was removed from the banned substances list in 2019. CBD is linked to many of the same pain relief and relaxation effects as THC, without the psychoactive effect or "high."

"This situation is super unfortunate and it's also unprecedented that someone with a failed doping test is allowed to compete in the Games. It's a complete slap in the face to every single athlete who comes here and competes clean," Rippon told Reuters.Rippon, who won bronze with the United States in the team event at the 2018 Pyeongchang Games, said he believed the decision by sport's highest court to allow the 15-year-old to compete after testing positive for the banned angina drug trimetazidine was unfair to other competitors.Valieva, who finished first in the short program on Tuesday (February 15), tested positive at her national championships on December 25 but the result was not revealed until February 8, after she had already competed at the Beijing Games in the team event. She will not face a hearing for her doping charge until well after the end of the Games. Olympic officials will not award the medals until the doping case is resolved.
Dutch troops used “extreme violence” — often deliberately — during Indonesia's 1940s war for independence, and military leaders and politicians in the Netherlands largely ignored the excesses, a long-running research project concluded in findings published Thursday. The 4 1/2-year investigation by experts from three historical research institutes contradicts the Dutch government's long-held view that the country's troops engaged in extreme violence only sporadically as they battled pro-independence forces in what became Indonesia.

HONG KONG (Reuters) -Hong Kong has identified more than 20,000 hotel rooms for quarantine accommodation, leader Carrie Lam said on Friday, as property developers piled in to show support as the global financial hub battles a surge in COVID-19 cases.
