Abstract
RATIONALE Flavors can alter the orosensory properties of tobacco products. Specifically, flavors can serve as an oral cue for smokeless tobacco products. OBJECTIVES We aimed to investigate the impact of oral vanillin, the principal chemical of vanilla flavor in tobacco products, on nicotine's taste, and nicotine choice, intake, and seeking behaviors. METHODS Experiments were performed in young adult Sprague Dawley rats. We employed a two-bottle free-choice test (2BC) to measure the preference for different concentrations of vanillin and its effect on nicotine preference. To explore the long-term effects of early exposure to sweetened vanillin, we utilized a combined 2BC and intraoral self-administration (IOSA) model. We assessed the nicotine taking and seeking behaviors in the presence or absence of vanillin. We performed a taste reactivity test (TRT) to quantify liking (ingestive) and disliking (aversive) taste responses to oral nicotine with or without vanillin. RESULTS In 2BC, female rats preferred vanillin containing solutions more than their male counterparts. In IOSA, vanillin alone and in combination with nicotine led to greater IOSA compared to water. Female rats self-administered vanillin plus nicotine more than male rats. Vanillin increased motivation to nicotine taking, but only in females. In TRT, vanillin increased nicotine's ingestive responses but blocked aversive responses in both sexes. CONCLUSIONS These results indicate that vanilla flavor can increase oral nicotine intake. It can also increase liking and decrease disliking of nicotine's taste. Furthermore, the impact of vanilla flavor on nicotine taste and nicotine choice, intake, and seeking behaviors is concentration and sex dependent.

Flavour loyalty may predict cessation or substitution following a cigarillo flavour ban among young adults in the USA. Tob Control 2022; 31:s206-s213. [PMID: 36328462 PMCID: PMC9641532 DOI: 10.1136/tc-2022-057487] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2022] [Accepted: 06/24/2022] [Indexed: 11/22/2022]
Abstract
Significance The purpose of this research was to measure flavour loyalty and identify how current cigarillo users may respond to a hypothetical flavour ban in the USA. Methods Cigarillo users aged 21–28 (n=531) were recruited between October 2020 and April 2021 to participate in an online survey. Respondents categorised their preferred, usual and current cigarillo flavours. Individuals who preferred tobacco flavours were compared with individuals who preferred any other flavours. Strength of preferences, or flavour loyalty, was defined when an individual’s preferred flavour matched what they use both usually and currently creating a spectrum of individuals with a strong tobacco preference (n=34), weak tobacco preference (n=20), weak flavour preference (n=162) and strong flavour preference (n=315). Those preferring tobacco were aggregated into any tobacco preference (n=54). Results Individuals who preferred any flavour scored higher on a scale of nicotine dependence. There was a dose–response relationship in those who said they would discontinue cigarillos if flavoured options were not available: 11.4% of individuals with any tobacco flavour preference, 27.8% of those with a weak flavour preference and 38.1% of those with a strong flavour preference. A similar trend was noted among those who would switch to another product: 19.2% of those with tobacco flavour preference, 34.3% of those with a weak flavour preference and 43.2% of those with a strong flavour preference. Conclusion Individuals who display strong flavour preferences were more likely to say they would discontinue use or seek out alternative flavoured products following a ban on flavoured cigarillos.
