Pot Politics: The Marijuana Business Comes To Washington

State by state, the legal marijuana business is slowly gaining ground. The industry is using both an increasingly favorable public opinion toward marijuana and a newly legal cash flow to try to transform itself into a force in national politics.

Recreational marijuana retailers celebrated their first anniversary of legal operation in Washington state Wednesday, while last week marked 18 months for the recreational cannabis business in Colorado. And Oregon legalized it July 1, though stores there won't open until 2016.
