Nationally, between 2011 and 2019, suicide was the second leading cause of injury death, and about half of all suicides were firearm related. An overlooked factor connecting firearms and suicide is lead exposure. Lead bullets and primers are used throughout the US and pose danger to adults and children. ⋯ Lead was a predictor of all suicide types. Our study appears to be the first to show the established firearm suicide relationships holds within municipalities in a single state. We provide evidence concerning the link between lead exposure and suicide, particularly from firearms, and provide a glimpse into the relationship between firearm prevalence and elevated blood lead levels.

Prevalence of and disparities in adolescents' susceptibility to novel oral nicotine products marketed as "tobacco-free".
Non-therapeutic, novel oral nicotine products are convenient, discreet to use, and flavored, with increasing sales in the United States. It is unclear whether these products appeal predominantly to adolescents already susceptible to inhalable nicotine products, or whether they attract adolescents who would not otherwise use nicotine. This study examined prevalence and correlates of susceptibility to inhalable and oral nicotine product use among adolescents. ⋯ Lower-socioeconomic status (SES) and sexual minority adolescents were more susceptible to oral (ORs = 1.76-1.87; ps < 0.05) and both products (ORs = 1.32-1.88; ps < 0.05), compared to higher-SES and heterosexual adolescents. Adolescents in Southern California may be more susceptible to e-cigarettes than other nicotine/tobacco products. However, appreciable numbers may be susceptible to oral nicotine products, including some youth who might not otherwise use nicotine and youth from populations historically impacted by tobacco-related health disparities.

Electronic cigarette use as an aid to quit smoking: Evidence from PASSI survey, 2014-2021.
This paper updates a previous cross-sectional study on the effectiveness of electronic cigarettes (e-cigarettes) as an aid to quit smoking. In the 2014-2021 PASSI survey, the ongoing Italian behavioural risk factor surveillance system, on a total of 239,812 subjects representative of the Italian adult population respondents who smoked and made at least one quit attempt in the previous 12 months (i.e., 19,234 subjects) were categorized into four groups according to the method used in their most recent quit attempt: no aid, e-cigarettes, standard pharmacological support (medications) and/or smoking cessation services (SCSs), other unspecified methods. The primary outcome was self-reported abstinence for a period ≥6 months. ⋯ No significant difference in abstinence was observed for those reporting no aid compared with e-cigarette users (adjusted Prevalence Ratio [aPR] = 0.93; 95% confidence interval [CI] = 0.79-1.10). Those using medications/SCSs were significantly more likely to report abstinence than e-cigarette users (aPR = 1.35; 95% CI = 1.01-1.81). E-cigarettes as consumer products are not associated with higher quitting rates than those recorded using no aid, therefore there is no health benefit for allowing them to be marketed to smokers.
