Oral nicotine pouches (ONPs) are an emergent class of tobacco products that, unlike conventional oral smokeless tobacco products, contain a nicotine powder instead of tobacco leaves. This review synthesizes available data on ONPs in key research domains including survey studies, marketing/advertising studies, chemical characterization and in vitro studies, and clinical studies. Research findings relevant for ONP regulations are summarized, including who uses these products and why, how marketing tactics influence appeal and use intentions, what harmful and potentially harmful constituents they contain, and what acute effects they have on humans.

To evaluate the label accuracy and content of various hemp-derived cannabidiol (CBD) products (cannabinoid products with ≤0.3% Δ-tetrahydrocannabinol [THC]), as well as evaluate advertised claims on product labels. Hemp haircare, cosmetics, and food/drink products that were advertised to contain CBD were purchased from retail stores in the Baltimore, Maryland area (purchased in July 2020) and online (purchased in August 2020).

Introduction: Little is known about patterns of dual use of tobacco and electronic cigarettes (e-cigarettes), especially regarding the factors that lead people to choose either product in particular situations. Identifying contextual factors that are associated with product use would enhance understanding of the maintenance of dual product use.

Methods: Individuals who dual use (N = 102) completed ecological momentary assessment surveys via text message regarding the recent use of tobacco and e-cigarettes for 2 weeks.

Article Synopsis
  • - Oral nicotine pouches (ONPs) are marketed as tobacco-free products containing crystalized nicotine powder and are available in various flavors; however, research on their usage and user experiences is limited.
  • - A survey of 118 adults using ONPs revealed that most participants also used traditional tobacco cigarettes or e-cigarettes, with flavor availability being the main motivation for use, and significant dependence levels identified.
  • - Adverse events reported included mouth lesions and stomach issues, and while the study's small and specific sample may limit the findings, it highlights the need for further research on ONP usage and its effects.

Introduction: There has been little research objectively examining use-patterns among individuals who use electronic cigarettes (e-cigarettes). The primary aim of this study was to identify patterns of e-cigarette use and categorize distinct use-groups by analyzing patterns of puff topography variables over time. The secondary aim was to identify the extent to which self-report questions about use accurately assess e-cigarette use-behavior.

Detailed assessment of smoking topography (puffing and post-puffing metrics) can lead to a better understanding of factors that influence tobacco use. Research suggests that portable mouthpiece-based devices used for puff topography measurement may alter natural smoking behavior. This paper evaluated the impact of a portable puff topography device (CReSS Pocket) on puffing & post-puffing topography using a wearable system, the Personal Automatic Cigarette Tracker v2 (PACT 2.

Introduction: The cue reactivity paradigm allows for systematic evaluation of motivational responses to drug-related cues that may elicit drug use. The literature on this topic has grown substantially in recent decades, and the methodology used to study cue reactivity has varied widely across studies. The present research provided a meta-analytic investigation of variables that have an impact on cue reactivity effects to enhance our understanding of this key feature of tobacco use disorders.

Introduction: Up to 24% of electronic cigarette (e-cigarette) users are concurrent users of both tobacco and e-cigarettes (dual users). Dual users provide an opportunity to assess key motivational processes supporting e-cigarette use, such as the reward value of e-cigarettes. This study used the Choice Behavior Under Cued Conditions procedure to examine cue-specific reactions to tobacco and e-cigarettes with a primary focus on evaluating the relative reward value of both forms of cigarettes.

Introduction: Craving may represent core motivational processes in tobacco dependence, but there is no psychometrically evaluated measure of craving for e-cigarettes (vaping craving). This research developed and validated a brief measure of vaping craving.

Methods: The measure was evaluated in two studies.
