According to the researchers, students who took 10 to 20 puffs per day scored 9% lower on cognitive tests than those who did not smoke or vape, but those who took more than 20 puffs per day scored almost 14% lower.
E-cigarettes, which have a lifespan of 20,000 puffs, are meant to be used for three months, but scientists found that many students were completely out of them before the end of the first month.
During the study, researchers conducted cognitive tests on more than 400 college students in Ecuador, ages 18 to 30. Of these, 64 were e-cigarette users, 31 were cigarette smokers, and 111 were both cigarette and e-cigarette users. They found that those who smoked e-cigarettes, e-cigarettes, or both had lower scores on cognitive tests than those who did not smoke or vape.
