California, Massachusetts and Nevada legalized marijuana on Tuesday, three more wins for the state-driven shift towards legalizing a substance the federal government still categorizes as a "most dangerous" drug.
Voters in Florida and North Dakota also approved medical marijuana measures. More than 60 percent of Florida voters backed a constitutional amendment making medical marijuana available for residents with debilitating illnesses whose doctors advised cannabis use.
North Dakota approved dispensing small amounts of marijuana to qualified patients registered with the state, or allowing those who reside far from dispensaries to legally grow their own.
The five measures passed as support for legalizing the substance is reaching new highs: 60 percent of Americans support making pot legal, according to a Gallup poll that's measured the trend for 47 years.
Arizona rejected the legalization of recreational marijuana, with 52.1 percent of the electorate voting no. Medical marijuana has been legal in the state since 1996.
Three other states weighed marijuana measures on Tuesday: Maine and Arkansas also also considering marijuana legalization, while Montana is considering medical cannabis measures. If all remaining measures are approved, marijuana could become legal in some form in 29 states.
