Globally, regulations vary. In the United States, the Combat Methamphetamine Epidemic Act of 2005 restricts the sale of ephedrine, requiring it to be sold behind the counter and limiting the quantity an individual can purchase. In Europe, it is categorized under controlled substances, and its sale is heavily restricted. The World Anti-Doping Agency (WADA) also bans its use in sports due to its performance-enhancing properties.
