According to a recent study from the National Center on Addiction and Substance Abuse at Columbia University, seventeen percent of high schoolers are either drunk, stoned or smoking cigarettes during school hours. That seems...about right? I don't know. It's been a while since I was in high school.

Anyway, as you might expect, almost everyone knows who the stoners are, and where they go to get stoned:

Some 86% told survey-takers that they were well aware their glassy-eyed classmates were stoned or drunk.

Half of the students polled said they know who deals drugs at school - and where students can go nearby to get high.

And the popular drugs are about what you'd guess:

Marijuana was the drug easiest to buy on school grounds, students said, followed by prescription drugs, cocaine and ecstasy.

But here's a new fangled twist, or at least something for parents to waste time worrying about:

The survey of 12- to 17-year-olds also found that seeing pictures on Facebook or MySpace of their pals partying made them want to get drunk or stoned themselves.

Some 75% said this kind of digital peer pressure is a major problem and 45% said they saw online photos of classmates drinking, doing drugs or even passing out.

These kids were four times likelier to have smoked pot, three times likelier to have used alcohol, and three times likelier to smoke cigarettes, the survey found.

By contrast, kids who didn't see these images on social networking sites were less likely to drink, do drugs, or smoke, the survey found.

Again, this is predictable: if you see your friends having a great time, you're more likely to want to join them. Drugs are fun, after all. And if you don't look at those party pictures and instead spend your time, like, I don't know, doing homework or something, you're probably going to get to college and become a raging alcoholic and then flunk out. So, kids, start your drinking and drugging early and often.
