HALLOWELL — A coalition of health and clean-air groups is applauding numbers showing smoke-free policies in public housing and privately owned rental units.

The Breathe Easy Coalition of Maine says 100 percent of the state’s public housing authorities have now adopted smoke-free policies.

The coalition also says a survey it commissioned shows that 47 percent of Maine renters are living in smoke-free housing, and 48 percent of landlords prohibit smoking in their buildings. The survey was conducted during the past two months.

The survey by Critical Insights of Portland also showed that 43 percent of tenants indicated willingness to pay more to live in smoke-free housing.

The Breathe Easy Coalition is an umbrella coalition of the Smoke-Free Housing Coalition of Maine, Maine Tobacco-Free Hospital Network, and Maine Tobacco-Free College Network.
