According to the nation’s most authoritative survey, the new General Social Survey, 51.7% of Americans thought marijuana should be legalized, with 41.7% opposed and 6.6% undecided in 2014.
In 2012, the last time the same question was asked, just 43.3% of Americans supported legalization adding new weight to efforts to legalize its use across the country.
Support is up 9 percentage points from 2012, the last time the survey was conducted.
The numbers rose steadily through the 1990s as states began adopting medical cannabis laws, starting with California in 1996.
Legalization supporters have been able to capitalize on that energy and secure full legalization in four states, with a partial legal status in DC.
