Rep. Earl Blumenauer (D-Ore. 3rd District), the co-chair of the Congressional Cannabis Caucus, joined Cheddar's "Cannabiz" to discuss the state of marijuana legalization on the federal level as more states continue to greenlight medical and adult use. He stated that there couldn't be a better time to revise the old policies on marijuana with more than 90 percent of Americans, including a majority of Republicans, on board. "This tidal wave of support continues. There were five states that approved in the last general election, and I think, rather than one single event, it is this momentum and the demonstration of broad public support that is making the difference," Blumenauer said.
