It found the number of U.S. teen boys who end up in emergency rooms for drinking related injuries doubles over the July 4th weekend.
On July 3 and 4, drinking sends a daily average of nearly 1,000 youth under 21 to the ER for problems related to alcohol use.
Two-thirds of them are male. The same problem is seen on other holiday weekends especially New Year's.
Experts say holidays are trigger points and this is a great opportunity for parents to talk to their children about their drinking behavior.
