When Was Pot a Performance Enhancer Drug??

American judo practitioner Nick Delpopolo was expelled from the London Games after testing positive for marijuana on Monday. (He claims he unknowingly ate food that had pot baked into it.) Weed is officially listed on the World Anti-Doping Agency's (WADA) list of banned substances, but scientists are calling its banning into question since pot doesn't offer athletes any noted physical advantages. Here, a brief guide to the controversy:
Can weed make you a better athlete?
The consensus: Not really. "I can't think of any sport in which [smoking pot] would be an advantage" in terms of enhancing a user's speed, strength, power, or precision, David Nutt, a professor of neuropsychopharmacology at Imperial College London, tells Reuters. "There's no evidence cannabis is ever performance enhancing in sport, and since its use is legal in a number of countries, there's no reason for it to be banned by the WADA," says Nutt. Other experts, however, contend that marijuana could prove useful in sports like shooting or golf where calm nerves and a steady hand are needed.

Why is it banned?
WADA uses two criteria to determine if an illegal substance goes on its list: Whether it can enhance athletic performance, and whether it is contrary to the spirit of sport. While cannabis won't improve performance in most competitions, evidence suggests it could have a "negative impact," saysReuters, pointing out that weed's active ingredient, THC, "increases blood pressure and heart rate while decreasing cardiac stroke volume, leading to diminished performances." In that sense, marijuana arguably meets WADA's second criterion. When asked to comment on why marijuana is considered a banned substance, WADA officials declined to comment.

Is that really why it's banned?
Well, other factors are probably at play. "The problem is the elite athletes should be seen as role models for young kids," said one British sports scientist who chose not to be named. WADA officials choose to ban cannabis "because they don't want to have the image of gold medalists smoking joints." But pot advocates accuse WADA of being inconsistent: The exact rules stipulate that "stimulants and anabolic steroids" should be illegal, says Brendan Ferreri-Hanberry at the Marijuana Policy Project."However, caffeine, a stimulant, is not on the list of prohibited substances," and the exact justification isn't clear.

Why is Michael Phelps still swimming while Delpopolo was expelled?
Under WADA's rules athletes can face a two-year ban if cannabis is found in their system "while they are in competition." When U.S. swimmer Michael Phelps was photographed allegedly smoking marijuana out of a glass pipe in 2009, he wasn't competing, and thus wasn't banned. Some scientists argue that "this smacks of double standards," says Reuters.
