By now you've heard about the amazing victories in Washington and Colorado, two states which voted to legalize cannabis at the state level on November 6. In Washington, possession of up to an ounce of cannabis will become legal on December 6 when the law comes into force. Prosecutors have already begun dropping hundreds of possession charges across the state. Washington state officials now have one year to figure out how to set up a state-run network of cannabis shops that will sell the herb to adults.
