Nicotine Pouch Awareness, Susceptibility, and Use Among California College Students
Availability of flavoured tobacco in San Francisco Bay Area stores after California’s statewide sales restriction
Menthol cigarette sales were rare, but sales of flavoured vapes persisted. Targets for further enforcement are tobacco specialty shops and FLUM. Contrary to expectation, duration of local laws was not associated with lower odds of violation, but the sample was limited to San Francisco Bay Area counties
Early assessment of compliance with California’s flavoured tobacco sales prohibition
This study revealed high rates of violations among vape shops within 4 to 7 months after the implementation of California's law. Efforts to improve retailer education and enforcement are warranted
Cigarette and cigarillo ads promote ‘flavour’ in a US state that prohibits flavoured tobacco sales
Rapid-response surveillance of the first US test market for VLN cigarettes
Retail marketing strategies for VLN mimic those for high-nicotine cigarettes. Deviations from FDA-authorised marketing claims were evident. Surveillance in future test markets is recommended to assess compliance with marketing claims and examine relative price and discount offers. Of interest is how premium-priced, low-nicotine cigarettes stand to compete in a market dominated by cheaper high-nicotine cigarettes
Impact of Local Flavored Tobacco Sales Restrictions on Policy-Related Attitudes and Tobacco Product Access
BACKGROUND: As of September 2020, more than 300 state and local jurisdictions restrict the sales of flavored tobacco, with some including menthol. AIMS: To evaluate the impact of local ordinances restricting the sale of flavored tobacco, we surveyed Californians regarding policy support and perceived access to flavored tobacco. METHODS: In 2019, we conducted an online survey of 3,075 California youth and young adults recruited via social media, a…
The Impact of Recent Tobacco Regulations and Covid-19 Restrictions and Implications for Future E-Cigarette Retail
Surveillance of tobacco retail, consumer behavior, and regulatory compliance is warranted as policies regarding nicotine and cannabis continue evolving
Implementation of a comprehensive flavoured tobacco product sales restriction and retail tobacco sales
San Francisco's comprehensive restriction virtually eliminated flavoured tobacco sales and decreased total tobacco sales in mainstream retailers. Unlike other US flavoured tobacco policy evaluations, there was no evidence of substitution to concept-flavour named products. Results may be attributed to San Francisco Department of Health's self-education and rigorous retailer education, as well as the law's rebuttable presumption of a product as fla…
Association between density and proximity of tobacco retail outlets with smoking
Vape shop and consumer activity during Covid-19 non-essential business closures in the USA
Many vape shops were non-compliant with state COVID-19 orders. E-cigarette users were as likely to stockpile vape products as to attempt to reduce or quit using e-cigarettes
Assurances of Voluntary Compliance
Objectives. To evaluate assurances of voluntary compliance (AVCs) between state attorneys general and retail chains by assessing e-cigarette sales to underage decoys and tobacco marketing violations in corporate-owned stores (that sign AVCs) and franchise stores (that do not sign AVCs). Methods. Decoys 18 to 19 years of age attempted to purchase e-cigarettes without presenting ID in California convenience stores (n = 540). Auditors characterized …
Marijuana as a ‘concept’ flavour for cigar products
Understanding how the tobacco industry manipulates cigar products and marketing to capitalise on the appeal of marijuana to youth and other priority populations is important to inform regulation, particularly for flavoured tobacco products. In addition, the retail availability of five and six packs of LCCs for ≤$1 near California schools underscores policy recommendations to establish minimum prices for multipacks
Negative affect, message reactance and perceived risk
Pictorial cigarette pack warnings increased quit intentions by increasing negative affect. Message reactance partially attenuated this increase in intentions. The opposing associations of negative affect and reactance on perceived risk may explain why pictorial warnings did not lead to observable changes in perceived risk
