Lettuce are welcoming some special guest non-profits for their fall tour dates this month, including the Cannabis Voter Project, a joint effort that teams voter engagement organization HeadCount with California’s CannaCraft cannabis manufacturer to help organize and educate voters on cannabis-related initiatives in their community.

The Cannabis Voter Project, along with the ACLU and WhyHunger?, are joining Lettuce on their October tour leg, through the band’s October 13 stop at Hillberry in Eureka Springs, AR.
