The Gallup poll was conducted from Oct. 1 to Oct. 10, just before Canada became the second country in the world to legalize marijuana. Meanwhile, in the U.S., voters in four states are considering ballot measures in the upcoming midterm elections that would allow recreational or medical marijuana use.

Past Gallup polling has indicated support for legalizing marijuana across political demographics. For the first time, the majority of Republicans joined Democrats last year in supporting legalization.
