to catch athletes who use drugs. The first tests for athletes were at the 1966 European Championships and two years later the IOC implemented their first drug tests at both the Summer and Winter Olympics. Anabolic steroids became prevalent during the 1970s and after a method of detection was found they were added to the IOC's prohibited substances list in 1975, after which the 1976 Summer Olympics in Montreal were the first Olympic games which tested for them. Over the years, different sporting bodies have evolved differently in the struggle against doping. Some, such as athletics and cycling, are becoming increasingly vigilant against doping. However, there has been criticism that sports such as football (soccer) and baseball are doing nothing about the issue, and letting athletes implicated in doping get away unpunished. Some commentators maintain that, as outright prevention of doping is an impossibility, all doping should be legalised. However, most disagree with this, pointing out the claimed harmful long-term effects of many doping agents. Opponents claim that with doping legal, all competitive athletes would be compelled to use drugs, and the net effect would be a level playing field but with widespread health consequences. A common rebuttal to this argument asserts that anti-doping efforts have been largely ineffective due to both testing limitations and lack of enforcement, and so sanctioned steroid use would not be markedly different from the situation already in existence. Another point of view is that doping could be legalized to some extent using a drug whitelist and medical counseling, such that medical safety is ensured, with all usage published. Under such a system, it is likely that athletes would attempt to cheat by exceeding official limits to try to gain an advantage; this could be considered conjecture as drug amounts do not always correlate linearly with performance gains. The influence of popular culture Social pressures Social pressure is one of the factors that leads to doping in sport. The media and society work together to construct a view of what masculinity and femininity should look like. Adolescent athletes are constantly influenced by what they see on the media, and some go to extreme measures to achieve the ideal image since society channels Judith Butler's definition of gender as a performative act. Examples of social pressures were given in a study done on an online bodybuilding community where bodybuilders doped because they felt like it was
