About the harms of electronic cigarettes, which he saw a lot of use to get rid of toxins that follow smoking, but the preliminary results say the opposite. Dozens of people, most of them teenagers, were transferred to hospital in the United States due to lung problems recorded in recent weeks with a common factor among them all, which is cigarette smoking It is not proven that the latter is responsible for these injuries.
And health services in the states of Illinois, Minnesota and Wisconsin in the north of the country recorded cases of coughing, shortness of breath, fatigue and dizziness after the spread of e-cigarettes.
In all, 30 cases were registered and investigations were opened in 22 of them.
Officials in the three states said it was too early to tell if these problems were interrelated.
"So far, e-cigarette smoking has emerged as the only common factor among all of these conditions, but we are trying to expand our research so that we don't miss anything," said Thomas Haupt, a respiratory specialist with the Wisconsin Health Service.
Some young people have smoked cannabis in e-cigarettes as well.
E-cigarettes have been available in the United States since 2006 and scientists so far consider them to be less harmful than a regular cigarette.
They are very prevalent among young people in the United States, as 3,6 million students in complementary schools and high schools smoked these cigarettes in 2018, according to the Centers for Disease Control and Prevention (CDC).
