A new report says BB guns and other non-powder guns injure as many as 21,000 Americans each year.
The report's release Monday comes just two weeks after an eight-year-old Columbia boy was accidentally killed by a 13-year-old friend with a non-powder gun. Those type guns kill an average of four Americans yearly.
From 1990 to 2000, there were 39 deaths and most of them involved children younger than 15.
The guns include powerful air rifles introduced in the 1970s and paintball pistols used in war games.
The report says they can cause internal injuries similar to those from bullets.
The report's author, Dr. Danielle Laraque, says the guns are being used as toys without thinking there may be a serious injury risk.
Statistics show thousands of injuries related to non-powder guns are treated each year.
