Young adults have disproportionately driven the shift toward public support of the drug, though support is rising among other generations as well. Millennials – those ages 18 to 35 in 2016 – are more than twice as likely to support legalization of marijuana as they were in 2006 (71% today, up from 34% in 2006), and are significantly more likely to support legalization than other generations.

Support for marijuana legalization has also increased among members of Generation X and Baby Boomers (ages 36-51 and 52-70 in 2016, respectively). More than half of Gen Xers (57%) support legalization, a considerable jump from just 21% in 1990. A majority of Boomers (56%) also support legalization, up from just 17% in 1990.
