Yes, They Need It Spelled Out For Them

They're kids, they don't know any better.

It turns out that growing up in a nonsmoking household isn't enough. According to researchers from the Boston University School of Public Health, if you don't want your kids to smoke, you need to take an extra step. Households that had an explicit ban on smoking did a better job of keeping their kids from using cigarettes than homes that were only populated by nonsmokers.

So much for leading by example. It's leading by example and then laying down the law in clear, black-and-white directives that gets things done. Have you ever tried getting through to a teenager? It makes sense that they wouldn't pick up on the subtle nuances of someone trying to act as a role model.

So to recap, firm ground rules and strict parenting are great ways to get your kids to stop smoking and start having sex.
