During lockdown, people are experiencing higher than usual levels of stress related to social isolation, employment, and finances that may result in lifestyle changes. Here, we aim to assess whether smoking habits changed during the lockdown measures due to coronavirus disease 2019 (COVID-19).

For the purpose of the survey, an online questionnaire was distributed from the tenth of April to the second of May 2020, among a Greek population, by using an online platform.

Two hundred smokers/vapers participated in the present survey (62.5% women, 44% of 36–45 years, 29% of 16–55 years, 15.5% 26–35 years). The daily number of cigarettes smoked before the onset of the COVID-19 pandemic is 15.06 ± 9.84, while during the restrictive measures due to COVID-19, the daily number of cigarettes smoked is 14.52 ± 10.13 (p > 0.05). Vapers consumed an average of 0.54 ± 2.43 mL vapor per day before the COVID-19 pandemic and 0.61 ± 2.81 mL during lockdown. Males smoked more cigarettes per day before (16.31 ± 11.87) and during the lockdown (15.33 ± 12.17) versus females (14.30 ± 8.36) and 14.04 ± 8.70, respectively) (p > 0.05 for both genders). Before versus during the restrictive measures, subjects that were primary school graduates smoked more cigarettes per day (28.00 ± 9.09 and 27.50 ± 9.57, respectively), followed by subjects that were high school graduates (16.90 ± 9.33 and 15.97 ± 9.50, respectively), university graduates (14.17 ± 10.14 and 13.93 ± 10.66, respectively), postgraduates (12.96 ± 9.52 and 12.25 ± 9.90, respectively) and middle school graduates (12.89 ± 8.22 and 14.22 ± 7.93, respectively).The self-reported reason for the change in the mL vaporized and the cigarettes smoked are confinement at home (36.3%), stress about COVID-19 (34.09%), free time (20.45%), boredom (4.54%), stress about the work status (2.27%), and participation in online lucky games (2.27%).

We did not observe significant differences in the daily consumption of smoke/vaping during the lockdown measures. More studies are needed to assess the long-term effects of the pandemic in smoking habits.
