"Compared to teens who have never seen pictures on Facebook, MySpace or another social networking site of kids getting drunk, passed out, or using drugs, teens who have seen such pictures are:
Four times likelier to have used marijuana (25 percent vs. 6 percent);
More than three times likelier to have used alcohol (43 percent vs. 13 percent); and
Almost three times likelier to have used tobacco (16 percent vs. 6 percent)."
