Tobacco control

To determine whether awareness of emerging vaping-attributable health conditions influences vaping-related risk perceptions and behaviours among young people. ⋯ News of vaping-attributable health conditions may prevent e-cigarette/vape use and encourage cessation among young people. Tobacco control campaigns should address uncertain health effects of e-cigarettes or vape products and align with risk communication by public health agencies during outbreaks.

This study examined sexual orientation differences in encoded exposure to tobacco product ads and intersections with race and ethnicity. ⋯ Sexual minority women of colour and black heterosexual women and men have increased encoded exposure to certain forms of tobacco ads. Further research is needed to address the impact of tobacco ads among multiple minority individuals based on sex, sexual orientation, race and ethnicity.

On 1 January 2016, Hawaii raised the minimum legal age for tobacco access from 18 to 21 years ('Tobacco 21 (T21)') statewide, with no special population exemptions. We assessed the impact of Hawaii's T21 policy on sales of cigarettes and large cigars/cigarillos in civilian food stores, including menthol/flavoured product sales share. ⋯ As part of a comprehensive approach to prevent or delay tobacco use initiation, T21 laws may help to reduce sales of cigarette and large cigar products most preferred by US youth and young adults.

The distribution of nicotine among its free-base (fb) and protonated forms in aerosolised nicotine affects inhalability. It has been manipulated in tobacco smoke and now in electronic cigarettes by the use of acids to de-freebase nicotine and form 'nicotine salts'. ⋯ First-generation e-liquids have α fb ≈ 1. At cigarette-like total nicotine concentration (Nictot) values of ~60 mg/mL, e-liquid aerosol droplets with α fb≈ 1 are harsh upon inhalation. The design evolution for e-liquids has paralleled that for smoked tobacco, giving a 'déjà vu' trajectory for α fb. For 17th-century 'air-cured' tobacco, α fb in the smoke particles was likely ≥ 0.5. The product α fbNictot in the smoke particles was high. 'Flue-curing' retains higher levels of leaf sugars, which are precursors for organic acids in tobacco smoke, resulting in α fb ≈ 0.02 and lowered harshness. Some tobacco cigarette formulations/designs have been adjusted to restore some nicotine sensory 'kick/impact' with α fb≈ 0.1, as for Marlboro. Overall, for tobacco smoke, the de-freebasing trajectory was α fb ≥ 0.5 → ~0 →~0.1, as compared with α fb= ~1 →~0.1 for e-cigarettes. For JUUL, the result has been, perhaps, an optimised, flavoured nicotine delivery system. The design evolution for e-cigarettes has made them more effective as substitutes to get smokers off combustibles. However, this evolution has likely made e-cigarette products vastly more addictive for never-smokers.

JUUL, a high-tech, popular vaping device, was the first major electronic cigarette (e-cigarette) brand to incorporate social media into its marketing strategy. There is growing concern around the increasing use of JUUL and other electronic nicotine delivery devices among youth, and their potential to addict a new generation to nicotine. The current study analysed the amount and characteristics of JUUL-related posts on Instagram, a social media platform used frequently among youth and young adults. ⋯ Findings reveal a proliferation of JUUL-related content on Instagram, which focused on product promotion and nicotine and addiction that included youth culture and lifestyle appeals. Regulatory actions should focus on restricting promotional efforts for e-cigarette products, particularly on social media platforms where young people are a primary audience.
