"Just Say No" was an advertising campaign during the 1980s and early 1990s. It was part of the U.S. "War on Drugs." The campaign wanted to discourage children from using illegal drug(s) and offered various ways of saying "no". "Just Say No" was also used by other organizations, such as DARE, to discourage violence and premarital sex. The slogan was created by First Lady of the United States, Nancy Reagan.[1]
