Introduction: Thirdhand smoke (THS) is the toxic residue of tobacco smoke that persists long after tobacco smoking on the clothing and hair of smokers and in the surrounding environment. This study aimed to assess parents' beliefs about THS in terms of harm and persistence in the environment and evaluate associations between parents' THS beliefs and home smoking rules.
Methods: A sample of parents living in Kuwait were enrolled in a cross-sectional study. Parents reported home smoking rules (strict, partial, and no, home smoking ban) and completed the 9-item Beliefs About ThirdHand Smoke (BATHS) scale that assessed parents' overall, health, and persistence beliefs about THS. Associations between the quartiles of THS overall, health, and persistence beliefs scores and home smoking rules were evaluated using a modified Poisson regression, and adjusted prevalence ratios (APR) and 95% confidence intervals (CI) were estimated.
Results: In total, 536 parents (404 females) were enrolled in the study, with 42.0% (n=225) and 43.6% (n=234) reporting a strict or partial home smoking ban, respectively. The prevalence of a strict home smoking ban was higher among never smokers than among ever smokers (49.1% vs 25.2%, p<0.001). The majority of participants indicated that THS exposure harms the health of children (67.2%) and adults (60.6%) and THS residue could remain for days in the environment (58.9%). The prevalence of a strict home smoking ban increased as THS overall (APR = 1.48; 95% CI: 1.12-1.96), health (APR = 1.22; 1.02-1.45), and persistence (APR = 1.55; 1.17-2.05) beliefs scores increased.
Conclusions: Parents' harm and persistence beliefs about THS were associated with enforcing a strict home smoking ban, which provides a safer environment for children and non-smokers. Therefore, tobacco prevention programs need to incorporate educational messages about the harm of THS in an attempt to promote smoke-free homes.

Article Synopsis
- Third-hand smoke (THS) is harmful residual smoke that remains on surfaces and can negatively affect respiratory health, especially in individuals with preexisting conditions.
- The study investigated how THS causes respiratory toxicity through mechanisms like increased reactive oxygen species (ROS), cytotoxicity, and inflammation in human airway cells.
- Findings indicated that THS leads to oxidative stress, as evidenced by increased levels of malondialdehyde and interleukin-6, along with decreased antioxidant activity, potentially exacerbating respiratory diseases.

Article Synopsis
- Environmental tobacco smoke (ETS), which includes second-hand (SHS) and third-hand smoke (THS), poses significant health risks, particularly for non-smokers and children who have higher exposure levels.
- The study analyzed tobacco-specific nitrosamines (TSNAs) from SHS and THS in a controlled room, finding differences in their concentration and distribution due to various factors like air exchange and particle deposition.
- The research highlighted that even limited exposure to THS leads to a concerning lifetime cancer risk, indicating the need for stronger smoke-free policies to mitigate health risks from ETS.
