"A 2005 study conducted by the American Medical Association reported that about one-third of teens said it was 'easy to obtain alcohol' from their parents. That figure jumps to 40 percent when it comes to getting alcohol from a friend's parent. One out of four teens said they had attended a party where minors were drinking in front of parents. Some communities are using their zoning powers to create local social hosting laws. These laws usually result in misdemeanor charges and jail time is rare. Prosecutors' offices are often busy with other cases and don't bother to charge unless there is a serious incident or accident, policy experts said."
