The Since U Been Gone singer told USA Weekend magazine that she used the drug while on a trip in Amsterdam. The singer, who has a good reputation, claims that she took advantage of the permissive laws in the Netherlands and ate a cookie that was laced with marijuana. Clarkson explained, "I don’t ever do anything illegal here (in America)… I’ve never tried any drugs," she told USA Weekend magazine. "I wouldn’t do anything that would cause holes in your brain or your nasal cavity."
Clarkson, who sold more than 11 million copies of her disc Breakaway, insists that she has never used drugs since her trip to Europe.
