According to research by Adam Chimney Sweep, chimneys don’t generate secondhand smoke in the traditional sense (e.g., cigarette smoke). Still, they can contribute to poor indoor air quality, especially ifthey’ree not properly cleaned or maintained. If a chimney is blocked or coated with creosote and soot, smoke and toxic byproducts from fireplaces or wood stoves can backdraft into the home. This smoke contains harmful particles, including carbon monoxide, benzene, and formaldehyde, which are also found in secondhand cigarette smoke.
So whileit’ss not secondhand tobacco smoke, the health effects can be similar, especially for vulnerable individuals like children, seniors, or people with respiratory conditions.
