More than two-thirds of Californians believe that the legalization of marijuana in the state has been a good thing and most want marijuana shops to be permitted to open in their towns.

In a poll published Tuesday conducted by the University of California Berkeley Institute of Governmental Studies, 68% of voters in California said they think that legalizing the sale, possession and personal use of pot among adults was a "good thing."

Just 30% of Californians think legalization has been a "bad thing."

Additionally, 63% of voters favor allowing retail marijuana dispensaries to sell cannabis products in neighborhoods where they live, while 36% do not.

California legalized marijuana in 2016 when 57% of voters approved Proposition 64, which allowed for the growing, selling and possession of cannabis for recreational use.

However, support varies among several demographics. More than three-quarters, 78%, of Democrats see legalization as a good thing, compared to less than half, 48%, of Republicans.

Young people, those aged 18 to 29, were the most likely to support legalization at 79%. People aged 65 and older were the least likely, though there was still a majority at 58%.

Additionally, African Americans are the race most likely to say legalization of pot in California was a good thing at 77%. Seventy-two percent of white people, 63% of Latinos and 62% of Asian Americans say the same.

Of the different neighborhoods in California, 66% of residents of the Central Valley area support the establishment of dispensaries. Los Angeles County residents follow closely at 65%, followed by residents of the San Francisco Bay Area at 64%.
