"One of the hottest-selling T-shirts among kids in New York and other American cities shows a crudely drawn snowman with a menacing expression.
The T-shirt was originally produced solely for Young Jeezy, a drug dealer-turned-rapper whose lyrics are laden with drug references, and kids and retailers say the snowman symbolizes the white substance colloquially called snow, or cocaine.
Anti-drug campaigners and education officials are alarmed, saying the T-shirt and others like it are part of sophisticated marketing campaigns which use coded symbols for drug culture that parents and teachers are not likely to understand. Some schools are banning kids from wearing the snowman images."
