Lipitor is not on the World Anti-Doping Agency (WADA) banned list. Lipitor is a brand name for atorvastatin, which is a medication used to lower cholesterol levels in the blood. According to Drug Patent Watch [1], atorvastatin is not listed on the WADA Prohibited List. The WADA Prohibited List is an international standard that identifies substances and methods prohibited in sports. However, it is important to note that athletes should always check with their respective sports organizations for specific banned substances.

Instead, the sources discuss the use of cannabis as a performance-enhancing drug and the drug testing policies of USA Powerlifting. Reuters [2] reports that cannabis is not considered a performance-enhancing drug by WADA, but it is still prohibited in competition. USA Powerlifting [3] also prohibits the use of cannabis and conducts drug testing to ensure compliance with their policies.

In conclusion, Lipitor is not on the WADA banned list. However, athletes should always check with their respective sports organizations for specific banned substances and comply with their drug testing policies.
