A majority of men favor marijuana legalization, while women are split. Younger Americans are especially likely to support legal marijuana use. There are partisan differences too: most Democrats think marijuana use should be legal, while most Republicans do not.

The percentage of Americans who say they have personally tried marijuana has grown since 1997, when CBS News last asked the question. Back then, just a third (34 percent) of Americans said they tried marijuana, but that percentage has risen to 43 percent today.
