"Just Say No" was a television avertising campaign, part of the US "War on Drugs" and prevalent during the 1980s and early 1990s, to discourage children from engaging in recreational drug use by offering various ways of saying no. Eventually, this also expanded the realm of "Just Say No" to violence, premarital sex, and any other vices that young people might try. The slogan was created and championed by former First Lady Nancy Reagan during her husband's presidency.
