In the 1990s, shortly after then-presidential candidate Bill Clinton claimed he "didn't inhale," only 25 percent of Americans wanted to legalize recreational marijuana. Today, that number has climbed to 58 percent, according to a new Gallup poll that shows a majority of Americans supporting the legalization of weed for the first time in U.S. history.
How did Americans learn to embrace pot? Here is a look at the evolution of marijuana laws and attitudes in the United States.

Infamous anti-drug propaganda film Reefer Madness, which later becomes a cult classic, is released.

Former Georgia Gov. Jimmy Carter calls for the federal decriminalization of marijuana during his presidential campaign, which would eliminate jail sentences for people caught with a small amount of the drug.
