Every so often, you'll see a sad or depressing Facebook post (or even write one yourself). But if it becomes too frequent, it could be a red flag. Facebook posts might predict whether a person is suffering from depression, researchers reported in Proceedings of the National Academy of Sciences.

Teens who "Juul" don't think they're dependent, but they just might be


Most people know that the popular e-cigarettes like Juul can easily be addictive, right? Apparently not many of the young people who smoke them. According to a study published in JAMA on Friday, most teens and young adults who use Juul brand e-cigarettes, which contain nicotine, fail to recognize that it's addictive. When Stanford University researchers asked teens if they felt addicted to the e-cigarette, most said "no" but provided answers to other questions that show they are, in fact, dependent.

“We need to help them understand the risks of addiction," the study’s senior author, Bonnie Halpern-Felsher, Ph.D wrote. "This is not a combustible cigarette, but it still contains an enormous amount of nicotine — at least as much as a pack of cigarettes.”

The news comes a few weeks after the FDA raided Juul's San Francisco headquarters, with many speculating the government is looking into it's advertisement strategies.

Siblings cooking in the kitchen

The Atlantic poses a really good question; Do parents or siblings influence a person more?
