(CNN) -- Following the liberal footsteps of Colorado and Washington, Alaska, Oregon and the District of Columbia passed ballot initiatives to legalize marijuana this month. Florida's medical marijuana law failed, but only because as a constitutional amendment it needed 60% support; 58% voted in favor of it.
In 2016, another five to 10 states will likely consider legalization -- possibly Arizona, California, Delaware, Hawaii, Maine, Maryland, Massachusetts, Montana, Nevada, New York, Rhode Island and Vermont. It's not surprising. Opinion polls show that marijuana legalization now commands majority support across the country.
Do these developments mean that full legalization is inevitable?
Not necessarily, but one would hope so. Marijuana legalization is a policy no-brainer. Any society that professes to value liberty should leave adults free to consume marijuana.
