Applying topic modelling and qualitative content analysis to identify and characterise ENDS product promotion and sales on Instagram

BackgroundIncreased public health and regulatory scrutiny concerning the youth vaping epidemic has led to greater attention to promotion and sales of vaping products on social media platforms.ObjectivesWe used unsupervised machine learning to identify and characterise sale offers of electronic nicotine delivery systems (ENDS) and associated products on Instagram. We examined types of sellers, geographic ENDS location and use of age verification.MethodsOur methodology was composed of three phases: data collection, topic modelling and content analysis. We used data mining approaches to query hashtags related to ENDS product use among young adults to collect Instagram posts. For topic modelling, we applied an unsupervised machine learning approach to thematically categorise and identify topic clusters associated with selling activity. Content analysis was then used to characterise offers for sale of ENDS products.ResultsFrom 70 725 posts, we identified 3331 engaged in sale of ENDS products. Posts originated from 20 different countries and were roughly split between individual (46.3%) and retail sellers (43.4%), with linked online sellers (8.8%) representing a smaller volume. ENDS products most frequently offered for sale were flavoured e-liquids (53.0%) and vaping devices (20.5%). Online sellers offering flavoured e-liquids were less likely to use age verification at point of purchase (29% vs 64%) compared with other products.ConclusionsInstagram is a global venue for unregulated ENDS sales, including flavoured products, and access to websites lacking age verification. Such posts may violate Instagram’s policies and US federal and state law, necessitating more robust review and enforcement to prevent ENDS uptake and access.

Natural Observation of Alcohol Price and Promotions at Bars: Implications for Alcohol Misuse Prevention

Alcohol misuse among young adults remains a primary public health concern given the wide range of short- and long-term physical, social, and societal consequences of the behavior. On-premise drinking establishments, which allow alcohol consumption on site (i.e., bars), are frequent locations for young adult alcohol use. Risks for alcohol misuse within the bar setting are key factors to identify for prevention. Notably, alcohol price and promotions are associated with alcohol consumption among young adults. This study sought to develop and pilot test an observational protocol to assess the alcohol environment at on-premise drinking establishments. Following qualitative exploration of salient risk factors in these settings through focus groups with young adults, an observational tool was adapted and tested in a feasibility study. The refined tool was then pilot tested with two independent data collectors conducting natural observation at 13 establishments in the downtown nightlife district of a small, southeastern city. High interrater reliability was noted. Descriptive summary statistics of bar characteristics demonstrate low alcohol prices with variability across types of alcohol (e.g., beer, wine, and liquor), greater numbers of alcohol promotions inside rather than outside the building, and higher rates of manual versus electronic age verification procedures. Observational assessment of alcohol price and marketing at on-premise drinking establishments as described in this study is needed to inform prevention policy and programs to reduce harms associated with young adult alcohol misuse.

Do you know the Wooly Bully? Testing Cultural Knowledge to Verify Participant Age

People in online studies sometimes misrepresent themselves. Regardless of their motive for doing so, participant misrepresentation threatens the validity of research. Here, we propose and evaluate a way to verify the age of online respondents: a test of cultural knowledge. Across six studies (N = 1,543), participants of various ages completed an age verification instrument. The instrument assessed familiarity with cultural phenomena (e.g., songs and tv shows) from decades past and present. We consistently found our instrument discriminated between people of different ages. In Studies 1a and 1b, age strongly correlated with performance on the instrument (mean r = .8). In Study 2, the instrument reliably detected imposters who we knew were misrepresenting their age. For impostors, age did not correlate with performance on the instrument (r. = .077). Finally in Studies 3a, 3b, and 3c, the instrument remained robust with people from racial minority groups, low educational backgrounds, and those who had recently immigrated to the US. Thus, our instrument shows promise for verifying the age of online respondents, and, as we discuss, our approach of assessing “insider knowledge” holds great promise for verifying other identities within online studies.

Cannabis and web marketing strategies-A study of Colorado cannabis vendors

PurposeThis study aimed to investigate the level of adoption of digital marketing by cannabis vendors in the state of Colorado.Design/methodology/approachThe study surveyed a random sample of 30 cannabis vendors in the state of Colorado. The analysis of the vendors’ use of digital marketing methods was conducted using a rubric based on a modified 7C Framework.FindingsIn the state of Colorado, the cannabis industry is nascent and has made an initial investment in digital marketing. While most companies had deployed a website, these websites featured basic elements of digital marketing. Though limited, the industry has made initial attempts to engage customers in a socially responsible manner. The industry would also benefit from better age verification, educational programs and profit sharing.Originality/valueThe study furthers the application of 7C Framework used in evaluating e-commerce sites for cannabis marketing.

Improving Retailer Compliance for Tobacco Purchases: Pilot Study Findings

Objectives: Those underage should not use tobacco products, including electronic nicotine delivery systems. A technologically-based solution developed by Juul Labs Inc to restrict underage access seeks to automate transactions, structurally mandate age-verification, and limit the quantity of JUUL products purchased per transaction. A pilot of this standards-based approach, referred to as RACS™ (Retail Access Control Standards), was conducted to assess efficacy. Methods: RACS was implemented at 171 stores within 3 retail chains selling tobacco products in 3 states. "Secret shopper" compliance audits, in which a mystery shopper attempted to purchase JUUL products, were conducted at participating stores before and after implementation of RACS, to test compliance with age-verification and product-quantity limits. Audit failure rates were compared pre- and post-RACS implementation to assess effectiveness. Comparisons were made overall, by chain, state, and failure type. Results: A total of 3990 audits were conducted. We found large, statistically significant reductions (p < .001) in failure rates for age-verification and compliance with product-quantity limits after implementing RACS, as compared to pre-RACS rates, declining to near zero. Conclusions: Utilizing enhanced access controls can be part of a comprehensive, evidence-based tobacco-control strategy to address underage use of all tobacco products, including JUUL.

Introduction to the Special Issue on JUUL Use

This special issue addresses key topics relating to the public health impact of the use of electronic nicotine delivery devices (ENDS), particularly JUUL-brand ENDS. Smokers smoke for nicotine, but are harmed by the byproducts of combustion. ENDS can play a role in tobacco harm reduction offering a noncombustible alternative source of nicotine for adult smokers who would otherwise continue smoking. Papers presented here estimate the prevalence of ENDS and JUUL use among young and older adults, and document the 12-month smoking trajectories of adults who purchased a JUUL Starter Kit. Overall, smoking prevalence was halved, with most smokers switching completely as dual use declined. This held for subpopulations defined by demographics and psychiatric comorbidity. For those who did not switch, most significantly reduced (50%+) their cigarette consumption. Another study reports that dependence declines as smokers switch from smoking to using JUUL. The public health potential of ENDS is undermined by use of ENDS by nonsmokers, especially underage individuals. Some smoking was reported by adult former and never smokers, with little evidence of persistent smoking, and lower risk of smoking among those using JUUL more frequently. Regarding underage use, one paper reports that technology can ensure age-verification at point of sale. Population modeling integrating impacts on diverse populations indicates that availability of ENDS is expected to avert millions of premature deaths in the US. We believe these papers make a substantial contribution to the field of tobacco science and smoking control.

A Model for Dental Age Verification Using Ultrastructural Imaging for Modern and Fossil Representatives of the Rhinocerotidae Family

The analyses were performed on a right third premolar (P3) of a white rhinoceros female (Ceratotherium simum, Burchell 1817). The specimen was born in captivity at London Zoo (Zoological Society of London), then in the 1970s transferred to Kiev Zoo (Peremohy Avenue), Ukraine, and was kept there until it died at a documented chronological age of 48 years. The female died because of its age, which indicates it was kept in good conditions adequate to the requirements of this species. Photographs and micrographs with radiological documentation were taken on the said tooth. Its structural characteristics were determined, and on the occlusal surface areas and points of anatomical constitution of its crown were identified. The tooth was also histologically evaluated via sections taken horizontally in a mesial-distal plane through the crown, horizontally in a mesial-distal plane through the coronal portion of the root, and longitudinally in a lingual-buccal plane through the crown and the root. Preparations with ground sections were made and observed in white, polarized, and reflected light. In the subsequent stage X-ray and SEM imaging has also been used, for analysis of the distribution of annual growth layers of mineralized dental tissues of cement and dentine, counted from the root canal center to the buccal surface. An attempt was also made to confirm the annual season in which the animal died, based on cement growth lines. It was observed that the growth lines were visible in all the analyzed sections, in dentine and cement. In the cement, the lines were relatively few and did not represent the attested age of the animal. The analysis of the coloration of the cement lines indicated that the animal was regularly fed a diet that was not seasonally differentiated. From the X-ray examination comes a conclusion that the animal did not suffer from periodontal diseases. Visible growth lines were observed on the dentine. On the horizontal section through the crown growth lines in the dentine were few and unclear. On the longitudinal section, both on the caudal and rostral roots, these lines were clearly visible and much more numerous than expected considering the known age of the animal, as more than 50 were counted. On horizontal sections through the upper part of both roots, distinct growth lines were observed in the dentine, and their number—48 for both roots—corresponded precisely to the age of the animal. The results of our study indicate that this method has significant potential for application to verify the age at death for modern and fossil representatives of rhinoceros.

Adolescent gambling and gambling-type games on social networking sites: Issues, concerns, and recommendations

Research indicates that compared to the general population, teenagers and students make the most use of social networking sites (SNSs). Although SNSs were originally developed to foster online communication between individuals, they now have the capability for other types of behaviour to be engaged in such as gambling and gaming. The present paper focuses on gambling and the playing of gambling-type games via SNSs and comprises a selective narrative overview of some of the main concerns and issues that have been voiced concerning gambling and gambling-type games played via social network sites. Overall, there is little empirical evidence relating to the psychosocial impact of adolescents engaging in gambling and gambling-type activities on SNSs, and the evidence that does exist does not allow definitive conclusions to be made. However, it is recommended that stricter age verification measures should be adopted for social games via SNSs particularly where children and adolescents are permitted to engage in gambling-related content, even where real money is not involved.
