Lower room temperatures and sleeping with parents also increase cotinine levels, highlighting the need for education on preventing passive smoking.
A study found that children with at least one smoker parent have significantly higher cotinine levels in their urine, quadrupling the risk for mothers and doubling it for fathers. Sleeping with parents and lower temperature rooms were also associated with increased cotinine levels.

The study found that male mice exposed to cigarette smoke had higher rates of genetic mutations than non-smoking mice, with the duration of exposure increasing the likelihood of damage.
Researchers measured pollutants from secondhand smoke near bars and restaurants with indoor smoking bans, finding a rise in pollutants associated with an increase in smokers. The study suggests that secondhand smoke is present in these outdoor zones, potentially creating unhealthy environments for non-smokers.

A large longitudinal study found that full-term, low-birth-weight babies are significantly more likely to develop respiratory symptoms, such as wheezing and coughing, between ages 1 and 5. Exposure to environmental tobacco smoke further increases the risk of these symptoms.
Implementing NICE-recommended smoking cessation interventions can benefit employees' health and employers' businesses. The interventions include short counselling sessions, nicotine replacement therapy, and group therapy to help smokers quit, resulting in reduced lost productivity and improved public health.

Research suggests that elderly people exposed to secondhand smoke are at a higher risk of developing dementia. The study found that those with high lifetime exposure were approximately 30% more likely to develop dementia than those with no exposure. High exposure was defined as more than 30 years of exposure to secondhand smoke.
A recent survey found that nearly 60% of US children ages 3-11 are exposed to secondhand smoke daily, with urban children suffering the highest rates. Pediatricians lack formal training on effectively addressing secondhand smoke-related issues, despite knowing its hazardous health consequences.
