Exploring the effects of cannabis health warnings on protective health intentions among US adults in legal recreational states.

Background: As cannabis policy trends toward liberalization, assessing cannabis health warning effects becomes increasingly important. This study investigated underlying mechanisms accounting for the effectiveness of cannabis health warnings on protective health intentions.

Method: A sample of 1,095 adults (21+) living in legal recreational US states who reported using cannabis in the past 12 months participated in an online experiment.

A systematic review of cannabis health warning research.

Background: Cannabis legalization provides an opportunity to communicate with consumers through mandated health warnings on cannabis packaging. However, research on cannabis health warnings is a nascent field. Therefore, a review is needed to synthesize cannabis health warning research and inform ongoing policy discussions.

Warning Labels as a Public Health Intervention: Effects and Challenges for Tobacco, Cannabis, and Opioid Medications.

Warning labels help consumers understand product risks, enabling informed decisions. Since the 1966 introduction of cigarette warning labels in the United States, research has determined the most effective message content (health effects information) and format (brand-free packaging with pictures). However, new challenges have emerged.

Reactance, Mortality Salience, and Skin-Cancer Prevention Among Young Adults.

In an experiment ( = 206) using skin cancer prevention messages and a 2 (mortality: salient, control) × 2 (freedom-limiting language: freedom-limiting, autonomy-supportive) independent-group design, we tested the terror management health model and integrated its predictions with the theory of psychological reactance. We used a sample of young adults because they are most at risk for excessive tanning. Consistent with the study predictions about proximal defenses, mortality salience significantly increased intentions to wear sunscreen all year around, relative to the control condition.

It's addiction at this Point": A qualitative examination of youth E-cigarette use trajectory in the United States.

E-cigarettes (electronic cigarettes) have been the most used tobacco product among US youth since 2014, reaching a plateau during the COVID-19 pandemic. Youth e-cigarette use is associated with negative health consequences such as impaired cognitive functioning. For many, the COVID-19 pandemic altered social interactions, harm perceptions, and product availability.

"I Get the Flavors and It Makes Me Love Vaping More": How and Why Youth Users Modify Electronic Nicotine Delivery Systems.

Introduction: Youth in the United States are using electronic nicotine delivery systems (ENDS) at a high rate. Modifications to ENDS by youth can introduce additional health hazards which have not been previously considered. To better understand these risks, we need more information on what these modifications are, the motivations behind them, and the sources of information on modifications.

When Cigarette Smoking Meets COVID-19: How the Two Types of Threat and Efficacy Perceptions Interactively Predict Danger Control and Fear Control Processes.

Growing evidence indicates that communicating the combined risk of smoking and COVID-19 encourages smoking cessation. Guided by the Extended Parallel Process Model (EPPM), we examined how perceived threats of smoking and COVID-19 independently and interactively predicted danger control responses (i.e.

The effects of death awareness and reactance on texting-and-driving prevention.

Using a 2 (mortality: salient, control) × 2 (freedom-limiting language: freedom-limiting, autonomy-supportive) independent-group design, this study examined the relationship between mortality salience and psychological reactance in the context of texting-and-driving prevention messages. The terror management health model and the theory of psychological reactance guided study predictions. Results showed mortality salience produced adaptive effects on attitudes toward texting-and-driving prevention and behavioral intentions to reduce unsafe driving practices.

General and Device-Specific Reasons for ENDS Use: A Qualitative Study with Adult ENDS Users.

Background: A scientific consensus on the public health impact of electronic nicotine delivery systems (ENDS) remains elusive. This is partly due to the wide variation in product characteristics often lumped together under one category. Research is needed to better understand what ENDS device type characteristics motivate their use by adults.

Disparities among smokers during the COVID-19 pandemic: Examination of COVID-19-related worries by sociodemographic factors in a U.S. Nationally representative survey.

Low-socioeconomic status (SES) and certain racial/ethnic minority groups disproportionately experience tobacco-related disease and death. Underserved populations of smokers may be at disproportionate risk for elevated stress and worry related to basic needs and healthcare during the pandemic, which could impede smoking cessation and exacerbate health disparities. This study examined whether experiences with stress and worry among smokers during the COVID-19 pandemic differed by sociodemographic factors, and whether these factors predicted serious psychological distress (SPD).

Examining reactions to smoking and COVID-19 risk messages: An experimental study with people who smoke.

Background: Smoking cigarettes worsens COVID-19 outcomes, and news media and health agencies have been communicating about that. However, few studies have examined how these messages affect attitudes, beliefs, and behavioral intentions of people who smoke. These are critical variables that can inform public health campaigns to motivate quitting smoking during the COVID-19 crisis.

Serious Psychological Distress Is Associated with Higher Intentions to Quit among Smokers during the COVID-19 Pandemic.

COVID-19 has increased the rates of serious psychological distress (SPD) among the general population. However, the SPD among smokers during the pandemic remains understudied. In a parent study, 1,004 U.

Are smokers scared by COVID-19 risk? How fear and comparative optimism influence smokers' intentions to take measures to quit smoking.

Research suggests that smoking may compound the risk of serious health problems to smokers who contract COVID-19. This study examines whether and how exposure to news stories reporting the severe COVID-19 risk to smokers may influence smokers' emotional responses (fear, anxiety, and sadness) and intentions to take measures to quit smoking. Current smokers in the US participated in an online experiment (N = 495) and were randomized to read smoking risk news stories or news stories reporting the combined risk of smoking and COVID-19.

Associations between COVID-19 risk perceptions and smoking and quitting behavior among U.S. adults.

Objectives: The COVID-19 pandemic may impact cigarette smokers' behaviors. Among smokers, perceptions about the risks of contracting COVID-19 and the severity of COVID-19 illness likely vary, and perceptions may be associated with individual smoking behavior. Our study measured smokers' perceptions of COVID-19 risks and their association with smoking and quitting outcomes.

"It's Cool, Modifying and All, but I Don't Want Anything Blowing Up on Me:" A Focus Group Study of Motivations to Modify Electronic Nicotine Delivery Systems (ENDS).

Introduction: Modifications to electronic nicoti ne delivery systems (ENDS) can pose health risks to users. This study explored users' motivations for modifying ENDS devices and how perceived risks of modifications influenced modification behaviors as product availability and device characteristics changed over time.

Method: We conducted nine focus groups (February-June 2020) with 32 current ENDS users (18+, used ENDS in the past 30 days, and had been using ENDS for more than 2 months).

Dripping Technology Use Among Young Adult E-Cigarette Users.

Background: Young adults are increasingly using electronic nicotine delivery systems (ENDS). The standard ENDS device involves an electric coil that heats a wick to vaporize an e-liquid solution. "Dripping" is another method that involves applying e-liquid directly to the coil.

Effects of modified risk tobacco product claims on consumer comprehension and risk perceptions of IQOS.

Introduction: Tobacco industry studies on consumers' perceptions of modified risk claims (MRCs) often had important omissions (eg, no control group, not investigating whether consumers understand what 'switching completely' means). This study examined the effects of IQOS MRCs on risk perceptions and behavioural intentions.

Method: Based on tobacco companies' MRCs, we manipulated three MRC language features: explanation about 'switching completely' (absent vs present), number of diseases (single vs multiple) and language certainty (hypothetical vs certain).

An experimental study of messages communicating potential harms of electronic cigarettes.

There has been an upsurge of e-cigarette use in the United States in recent years. While e-cigarettes may contain lower levels of toxic chemicals than combusted cigarettes, they still pose serious health hazards, including increased risk for heart and respiratory disease. Despite these risks, public awareness of the health harms of e-cigarettes remains low.

Vaping, smartphones, and social media use among young adults: Snapchat is the platform of choice for young adult vapers.

Background: Tobacco use often begins or stabilizes in young adulthood. Approximately 90% of young adults use social media and over 80% own a smartphone. Retailers of electronic nicotine delivery systems (ENDS) have targeted smartphones and social media with adverting campaigns.

Modifications to Electronic Nicotine Delivery Systems: Content Analysis of YouTube Videos.

Background: As user modification can alter the addictiveness and toxicity of electronic nicotine delivery systems (ENDS), more research is needed to understand the types, motivations, risks, and information sources that lead to these product alterations. YouTube has been identified as a major platform where ENDS users obtain and share information about ENDS products and modifications. However, a comprehensive study of ENDS modification videos on YouTube is lacking.
