4 Your Health: teens not as aware of dangers from smoking and vaping; steroids not as effective during asthma attacks

Posted: Updated:

A new study suggests increasing the dosage of inhaled steroids when symptoms worsen does not help prevent asthma attacks.

Researchers at the University Of Wisconsin tracked 250 children with mild to moderate asthma for one year. Kids given a higher dose of steroids at the first signs of coughing or wheezing had a similar number of severe flare-ups as those who continued taking a low dose.

E-cigarettes contain toxins

Teens may think E-cigarettes are safe but a new study finds vapers are exposed to cancer causing toxins.

Researchers analyzed three groups of teens: E-cigarette users, smokers, and non-smokers. E-cigarette users had up to*triple the amount of toxins in their urine than non-smokers.

Experts say warnings to teens should include information about the potential risks of these products.

Rise in those who don't think smoking is dangerous

A separate Duke University study suggests fewer Americans think smoking is bad for you.

The number of people who said smoking a pack or more a day poses a great health risk dropped by one percent between 2006 and 2015. That represents more than three million Americans.

Teens and current smokers were least likely to see smoking as dangerous.
