The California Senate recently passed a proposal to ban smoking in apartments. The proposal would allow landlords to prohibit smoking in apartment buildings they own to protect nonsmoking tenants from second hand smoke, according the Los Angeles Times.

The measure will strengthen previous anti-smoking measures that bar Californians lighting up in many public places, including playgrounds, concert halls, restaurants, offices and some beaches.

The proposal, similar to a measure in Utah, is supported by the California Apartment Association, which represents about 50,000 property owners. But the Western Center on Law and Poverty argued that the proposal discriminates against the poor, the disabled and people of color, who smoke and rent at higher rates than other segments of the population.
