“…For example, it is unlikely that 45% of those in our sample who ever-used e-cigarettes had never used ones containing nicotine, a rate higher than the general population. 7 Future work will assess uptake and impact of tobacco-cessation efforts on e-cigarette use behavior, and the relationship between e-cigarette use and cancer diagnosis and outcomes among this sample.…”

Background and ObjectivesWe provide an initial characterization of e‐cigarette use among adult cancer patients.MethodsData were collected between November 2020 and August 2022 at a comprehensive cancer center.ResultsRelatively few (4.59%) of the assessed patients (n = 47,117) reported ever using e‐cigarettes. Over one‐third of current e‐cigarette users reported being current combustible cigarette users.Discussion and ConclusionsThese data suggest that e‐cigarette use is uncommon but associated with other tobacco use among adult cancer patients.Scientific SignificanceThis is among the first comprehensive surveys of adult cancer patient e‐cigarette use that details the types of e‐cigarette and other tobacco products used by this population.

“…The examination of the flavors used across e-cigarette devices revealed that fruit was the most commonly reported flavor type ever used among 13-20-year-olds and 21-24-year-olds (59.0% < 21; 57.8% 21-24), ever used in the past 30 days (50.4% < 21; 50.9% 21-24), and the most used in the past 30 days (39.9% < 21; 38.8% [21][22][23][24]. Sweet/dessert/candy was the most commonly reported flavor type among 25-40-year-olds ever (50.9%).…”

This study assesses the use of e-cigarette devices and flavors using a large, cross-sectional survey of adolescents, young adults, and adults (N = 6131; ages 13–40 years old; Mage = 21.9) conducted from November to December 2021, 22 months after the FDA announced its prioritized enforcement policy against some flavored pod/cartridge-based e-cigarettes. We analyzed the patterns of use by age group: adolescents and young adults (AYAs) under 21 (minimum age of e-cigarette sales), young adults (21–24 years old), and adults (25–40 years old). The participants reported using e-cigarettes ever (44.2% < 21; 67.1% 21–24; 58.0% > 24), in the past 30 days (29.8% < 21; 52.6% 21–24; 43.3% > 24), and in the past 7 days (24.5% < 21; 43.9% 21–24; 36.5% > 24). Disposables were the most used e-cigarette device type across age groups (39.1% < 21; 36.9% 21–24; 34.5% > 24). Fruit, sweet, mint, and menthol flavors were popular across age groups; however, chi-squared tests for trends in proportions revealed age-related trends in past 30-day flavor use by device type. Findings suggest current AYA e-cigarette use may be higher than recorded by the NYTS 2021. The FDA, states, and localities should adopt more comprehensive restrictions on flavored e-cigarette products in order to reduce adolescent and young adult e-cigarette use.

“…The online sample was balanced for gender and race and ethnicity (as per the latest US census data). It was important to include race and ethnicity in the analyses as studies show that there are racial and ethnic differences in cigarette and e-cigarette use . We used quota sampling to purposely balance the proportion of e-cigarette ever users (50.2%) and nonusers (49.8%) in our sample, and equal proportions of participants stratified by 3 age groups (age 13-17 years, termed adolescents [33.7%], age 18-20 years [41.6%] and 21-24 years [24.7%], collectively referred to as young adults in this study) .…”

ImportanceDespite increasing use of cigarettes and electronic cigarettes (e-cigarettes) and related health effects among youth, few studies have reported their effects on eyes.ObjectiveTo examine the frequency and severity of ocular symptoms (ocular discomfort, pain, burning, itching, redness, dryness, glare, blurriness, strain, and headaches) in young e-cigarette and cigarette users.Design, Setting, and ParticipantsIn an observational cross-sectional study, a survey conducted in May 6 to 14, 2020, asked participants about use (ever, past 30 days, and past 7 days) of e-cigarettes and cigarettes. The participants included US individuals aged 13 to 24 years.Main Outcomes and MeasuresAssociations between vision-related outcomes (general vision, severity/frequency of ocular symptoms) and tobacco use were analyzed using weighted multivariable logistic regressions, adjusting for sociodemographic factors, contact lens use, and other combustible use.ResultsThere were 2168 never users, 2183 ever users, 1092 past 30-day users, and 919 past 7-day users of e-cigarettes; 55.9% of e-cigarette ever users also used cigarettes (dual users). Of the 4351 respondents, 63.8% identified as female, and mean (SD) age was 19.1 (2.9) years. Between 1.1% and 3.9% of ever dual users reported severe to very severe ocular symptoms; between 0.9% and 4.3% reported daily symptoms, which was higher than the proportion of symptoms in e-cigarette- or cigarette-only users. Past 7-day dual users had more severe itching (adjusted odds ratio [AOR], 2.37; 95% CI, 1.36-4.13; P = .002), redness (AOR, 2.58; 95% CI, 1.50-4.46; P = .001), dryness (AOR, 2.89; 95% CI, 1.64-5.08; P &lt; .001), glare (AOR, 2.56; 95% CI, 1.50-4.35; P = .001), blurriness (AOR, 2.47; 95% CI, 1.36-4.50; P = .003), headaches (AOR, 2.31; 95% CI, 1.34-4.00; P = .003); and more frequent pain (AOR, 3.45; 95% CI, 2.09-5.68; P &lt; .001), burning (AOR, 3.08; 95% CI, 1.86-5.09; P &lt; .001), and redness (AOR, 2.72; 95% CI, 1.69-4.36; P &lt; .001) than all other participants. Past 30-day dual users had more severe dryness (AOR, 2.65; 95% CI, 1.61-4.36; P &lt; .001) and more frequent pain (AOR, 3.33; 95% CI, 2.12-5.21; P &lt; .001) than all other participants. Ever dual users experienced more severe dryness (AOR, 1.60; 95% CI, 1.05-2.43; P = .03) and blurriness (AOR, 1.79; 95% CI, 1.21-2.64; P = .003) and more frequent pain (AOR, 1.69; 95% CI, 1.13-2.53; P = .01) and blurriness (AOR, 1.63; 95% CI, 1.13-2.36; P = .009) than never users.Conclusions and RelevanceIn this cross-sectional US study, adolescents and young adult users of both e-cigarettes and cigarettes had a higher likelihood of experiencing severe and frequent ocular symptoms, with past 7-day users reporting more symptoms than past 30-day users or ever users. These findings provide additional reasons for users of e-cigarettes and cigarettes to reduce their tobacco use to possibly prevent or minimize ocular symptoms.
