Lower weight gain after vaping cessation than after smoking quitting

Background: Smoking is frequently a way to control appetite and weight. The data concerning the body mass gain after quitting among the users of electronic cigarettes who have no prior history of smoking traditional cigarettes is inconsistent. Objective: In our study we have compared smoking and vaping impact on weight gain and glycaemia. Material and methods: 3 groups of rats were used. The group A was exposed to vapour and group B were exposed to smoke. Rats in the group C constituted the control group without nicotine exposition. Results: During 6 weeks of experiment weight gain of rats in the A and B groups was comparable, while animals from group C had gained signifi0cantly more. During 2 weeks after cessation of exposition to nicotine animals from group B gained more weight than rats of A and C group. Blood glucose was higher in group B than in groups A and C 24 h after last exposure to nicotine and 2 weeks after nicotine exposure cessation. Conclusion: Effects of vaping on weight increase is similar to smoking, but after vaping cassation weight gain is lower and comparable with nicotine nonusers.
