Self-reported use of cannabidiol as a substitute or adjunct for approved medications
Objective: To assess the prevalence of CBD use among US adults, identify the health conditions for which CBD is used, and examine whether CBD is used as a substitute or adjunct to conventional treatments. Design setting and participants: This cross-sectional survey used Ipsos KnowledgePanel®, a US probability-based online panel covering approximately 97% of US adults and including households without internet access (which are provided internet se…
Migration intention and Indigenous social networks in the place of origin
Internet Searches for Lorazepam Following the Release of The White Lotus
This cross-sectional study examines whether there was an uptick in online searches about lorazepam after the release of the third season of The White Lotus
Online retailer noncompliance to e-cigarette excise tax and tobacco licensing laws
Many online vape retailers fail to comply with California's excise tax and licensing laws. Low compliance rates indicate existing enforcement mechanisms are not optimised for online sales. Enhancing oversight and enforcement of excise tax laws for online retailers is crucial to reduce tax non-compliance, prevent revenue loss and support public health
State Cannabis and Psychedelic Legislation and Microdosing Interest in the US
This cross-sectional study found that state-led legislative reforms on cannabis and psychedelics were associated with increased public interest in microdosing psychedelics
Need for improved regulation of tobacco e-commerce
Cigarette smoking decline among US young adults from 2000 to 2019, in relation to state-level cigarette price and tobacco control expenditure
National programmes may have filled a gap in state-level interventions, helping drive down the social acceptability of cigarette smoking among young adults across all states. Additional interventions are needed to assist high-prevalence states to further reduce smoking
Comparing Physician and Artificial Intelligence Chatbot Responses to Patient Questions Posted to a Public Social Media Forum
Importance The rapid expansion of virtual health care has caused a surge in patient messages concomitant with more work and burnout among health care professionals. Artificial intelligence (AI) assistants could potentially aid in creating answers to patient questions by drafting responses that could be reviewed by clinicians. Objective To evaluate the ability of an AI chatbot assistant (ChatGPT), released in November 2022, to provide quality and …
Declines in cigarette smoking among US adolescents and young adults
Since 1997, a large decline in cigarette smoking occurred in the US population under age 24 years, that was independent of the 2017-19 adolescent surge in past 30-day e-cigarette vaping. Further research is needed to assess whether the 2014-15 to 2018-19 increase in exclusive vaping in those aged 18-24 years is a cohort effect from earlier dependence on e-cigarette vaping as adolescents
E-commerce licensing loopholes
These findings raise concerns about potential loopholes in policy enforcement created by the absence of explicit regulations on e-commerce sales in retailer licensing programmes. Strengthening regulations to include e-commerce and monitoring e-commerce compliance are recommended to enhance the impact of laws enforced through retailer licensing programmes
Effectiveness of e-cigarettes as aids for smoking cessation
Sales increases in high nicotine e-cigarettes in 2017 did not translate to more smokers using these e-cigarettes to quit smoking. On average, using e-cigarettes for cessation in 2017 did not improve successful quitting or prevent relapse
Evaluating US smokers’ willingness to pay for different cigarette packaging designs before and after real-world exposure in a randomised trial
Compared with US branded packs, the negative valuation of non-branded GWL packs attenuates with even 3 months' use but does not generalise to non-used GWLs. This suggests that GWLs should be regularly refreshed. The appeal valuation of industry imagery suggests that the US plan to retain such imagery on packs may ameliorate the effect of GWLs
Public interest in ∆8-Tetrahydrocannabinol (delta-8-THC) increased in US states that restricted ∆9-Tetrahydrocannabinol (delta-9-THC) use
Through our own eyes and voices
Migration from Central America to the United States has become a strategy to escape economic poverty, exclusionary state policies and violence for people of Mayan descent. Under the principles Community Based Participatory Research, we explored the health concerns of Indigenous Mayans in rural migrant-sending communities of Guatemala using their own visual images and narratives through a Social Constructivist lens. Half of households in the study…
Characterizing Self-Reports of Self-Identified Patient Experiences with Methadone Maintenance Treatment on an Online Community during Covid-19
Patients described unanticipated consequences to one-size-fits-all policies that are unevenly applied resulting in suboptimal dosing, increased perceived risk of acquiring COVID-19 at OTPs, and reduced interaction with OTP providers and staff. While preliminary, these results are formative for follow-up surveillance metrics for patients of OTPs as well as digitally-mediated resource needs for this online community. This study serves as a model of…
Availability and Promotion of Cannabidiol (CBD) Products in Online Vape Shops
Vaping products containing cannabidiol (CBD), a cannabis-derived compound used in wellness products and available in all 50 US states, were recently implicated in outbreaks of poisonings. Little is known about the commercial availability of CBD products in vape shops (i.e., stores that sell e-cigarettes). To document the availability and marketing of CBD products in online vape shops, in June 2020, we used the Google Chrome browser without cached…
Google shopping queries for vaping products, Juul and Iqos during the E-cigarette, or Vaping, product use Associated Lung Injury (Evali) outbreak
These results suggest that unplanned events, such as the EVALI outbreak, can provoke changes in the epidemiology of product usage. Tobacco companies should be prohibited from using events such as disease outbreaks to position their products as less harmful without prior approval
Effects of menthol use and transitions in use on short-term and long-term cessation from cigarettes among US smokers
These results demonstrate that menthol impaired menthol smokers' attempts to quit smoking but switching from menthol improved success. This suggests that removing menthol may improve menthol smokers' success during quit attempts
Did Philip Morris International use the e-cigarette, or vaping, product use associated lung injury (Evali) outbreak to market Iqos heated tobacco
25 July 2021 will mark the second anniversary1 of the e-cigarette, or vaping, product use associated lung injury (EVALI) outbreak.2 The concerns raised and news media attention focused on EVALI created a fertile environment for the tobacco industry to promote their e-cigarette alternatives,1 3 but this has not been studied. One such product is Philip Morris International’s (PMI) heated tobacco product: ‘IQOS’.4 5 To assess how PMI promoted IQOS i…
Role of affective reactivity induced by cigarette packaging including graphic warning labels
Initial reactions to GWL packs, a blank pack, and smokers' current US pack reflected negative, neutral, and positive affect, respectively. Different versions of the GWL pack elicited different levels and types of immediate negative affect

News coverage of the E-cigarette, or Vaping, product use Associated Lung Injury (Evali) outbreak and internet searches for vaping cessation
The vaping-induced pulmonary disease outbreak spawned increased coverage about the dangers of vaping and internet searches for vaping cessation. Resources and strategies that respond to this elevated interest should become a priority among public health leaders
A Philip Morris advertisement for its heated tobacco product Iqos sets a troubling precedent
Philip Morris was allowed to market its IQOS brand of heated (or 'heat-not-burn') tobacco in the USA in April 2019 after receiving a marketing order from the Food and Drug Administration (FDA) requiring it to follow existing tobacco marketing regulations, as well as new reporting requirements that mandate Philip Morris ensures consumers are properly informed about the dangers of IQOS and minors are not targeted.1 However, as early as August 2019,…
What to do when tobacco advertisers exploit antitobacco social media campaigns to sell tobacco
Public health antitobacco campaigns on social media reach a broad audience and can foster public engagement in active conversations that are not possible with traditional media channels such as television or radio.1 This new level of engagement, however, brings added challenges, chiefly the potential to lose control of a message. For instance, antitobacco campaigns can be attacked by counter-campaigns that can dilute and overwhelm a public health…
E-Cigarette Use in the Past and Quitting Behavior in the Future
Objectives. We examined whether smokers who used e-cigarettes are more likely to quit after 1 year than smokers who had never used e-cigarettes. Methods. We surveyed California smokers (n = 1000) at 2 time points 1 year apart. We conducted logistic regression analyses to determine whether history of e-cigarette use at baseline predicted quitting behavior at follow-up, adjusting for demographics and smoking behavior at baseline. We limited analyse…

Is Gray Water the Key to Unlocking Water for Resource-Poor Areas of the Middle East, North Africa, and Other Arid Regions of the World
Smokers who report smoking but do not consider themselves smokers
Smoking surveillance should restructure selection criteria to more accurately account for NIS in areas with high stigma toward smokers. Targeted interventions may be needed for NIS including educating healthcare providers to enquire more deeply into smoking habits
Is Gray Water the Key to Unlocking Water for Resource-Poor Areas of the Middle East, North Africa, and Other Arid Regions of the World
Recall of Anti-Tobacco Advertisements and Effects on Quitting Behavior
Objectives. We assessed whether an anti-tobacco television advertisement called “Stages,” which depicted a woman giving a brief emotional narrative of her experiences with tobacco use, would be recalled more often and have a greater effect on smoking cessation than 3 other advertisements with different intended themes. Methods. Our data were derived from a sample of 2596 California adult smokers. We used multivariable log-binomial and modified Po…
