In the event of an accident, a lit cigarette also becomes a fire risk
Instead, the FDA suggests that companies should rework their batteries to make them less likely to overheat
In a letter to Health and Human Services (HHS) Secretary Xavier Becerra and members of Congress, the ACLU noted that about 80% of Black smokers prefer menthol cigarettes, and warned the ban "will trigger criminal penalties, which will disproportionately impact people of color," lead to "constitutional policing," and "prioritize criminalization over public health and harm reduction." While acknowledging that it would be best if no one smoked, the ACLU also seemed to question the necessity of the menthol ban, citing government data showing "cigarette use is down to 2.3% from 13% in 2002" and that among underage African-Americans it's down to 1.1%

The increase in the immature macrophages seen in smokers may be due to the influx of monocyte-derived cells from the peripheral blood, with the additional increase due to AM proliferation within the lung.38 CS exposure and AM immune function Transcriptional profile and inflammation A number of studies have looked at the transcriptional profiles of human AMs isolated from smokers compared with non-smokers.36 47 48 The differential in gene expression belongs to the functional categories of immune/inflammatory response, lysosomal function, antioxidant-related function, signal transduction, regulation of transcription, cell adhesion, ECM and proteinase/anti-proteinase production.48 One such difference was an increase in osteopontin expression in smokers (fourfold), which was confirmed at the protein level and correlated with airflow obstruction
