Cigarette, E-Cigarette and Waterpipe Use among Young Adults: Differential Cognitions about These Three Forms of Smoking

Background: Polytobacco use is common among young adults. The purpose of the present study was to investigate a number of cognitions related to the use of three tobacco products (cigarettes, e-cigarettes and waterpipes) among young adults. Methods: Participants (n = 799, 59.4% women) aged 18–25 years old (M = 21.8, SD = 1.7) completed an online tobacco cognitions questionnaire. Results: For all three tobacco products, there was significantly more agreement with the cognition “I would smoke if my best friend offered” among tobacco users (used one or more tobacco products) than among non-users. For e-cigarettes and waterpipes, there was significantly more agreement with the cognition “It would be easy to quit these products” than was reported by non-users. Polytobacco users (three tobacco products) endorsed the cognitions scale (the six cognition items were combined to form a single cognitions scale for each tobacco product) significantly more than non-users for cigarettes and e-cigarettes. Furthermore, waterpipe users, polytobacco users, dual users and single users all endorsed the combined cognitions scales more strongly than non-users. Conclusions: Efforts to prevent polytobacco use should ensure that young adults have the necessary self-efficacy to resist peer pressure and provide them with clear information about the health risks associated with using alternative tobacco products.
