Arsenic is measurable in tobacco and cigarette mainstream smoke (MSS). Whether arsenic has an independent role in diseases associated with tobacco consumption is not known. Epidemiology and biomonitoring data and probabilistic risk assessment (PRA) methods were used to investigate this potential association. Analysis of data from the National Health and Nutrition Examination Survey (NHANES) showed that urine arsenic concentrations in tobacco consumers were not different or were lower than levels in non-consumers of tobacco. Additionally, urine arsenic levels from NHANES tobacco consumers were five-times or more lower than levels reported in epidemiology studies to be associated with adverse health effects. Results of PRA indicated that mean non-cancer hazard estimates and mean incremental lifetime cancer risk estimates were within accepted ranges. Taken together, these results suggest that arsenic may not be independently associated with tobacco consumption or diseases related to tobacco consumption.

Background: In May 2020, Oakland became the most populous city in California to implement a minimum floor price law (MFPL), requiring tobacco retailers to sell cigarettes and cigars at $8 or more per pack/package. Policy enforcement began in August 2020.
Methods: We estimated changes in cigarette and cigar prices and unit sales for Oakland versus a matched comparator during the first 20 months following MFPL implementation using a synthetic difference-in-differences approach.

The eradication of the commercial tobacco industry is a crucial goal for health and well-being, particularly from a public health and health justice perspective. The term 'eradication' is applied in epidemiology to mean the process and outcome of elimination of the-commercial tobacco industry as a human-made-agent of disease and death. In this commentary, we outline why the eradication of the tobacco industry is necessary, urgent and realistic.

Background: Individual neurobiological heterogeneity among patients with tobacco use disorder (TUD) hampers the identification of neuroimaging phenotypes.
Methods: The current study recruited 122 TUD individuals and 57 healthy controls, and obtained their 3D-T1 images. Heterogeneity through discriminative analysis (HYDRA) was applied to uncover the potential subtype of TUD where regional gray matter volume (GMV) was treated as the feature.

Introduction: Healthcare avoidance and delay (HAD) is prevalent among transgender (trans) populations. This study sought to identify patterns of HAD and examine associations between HAD and 5 behavioral health outcomes among trans adults: depression, anxiety, tobacco and alcohol use, and intimate partner violence (IPV).
Methods: This study used survey data collected in 2023 from 789 trans adults in Washington state.

Calcium-dependent protein kinases (CDPKs) are very effective calcium signal decoders due to their unique structure, which mediates substrate-specific [Ca] signalling through phosphorylation. However, Ca-dependence makes it challenging to study CDPKs. This work focused on the effects of the overexpression of native and modified forms of the AtCPK1 gene on the tolerance of tobacco plants to heat and cold.
