Red Ribbon Week is the oldest and largest drug prevention campaign in the country. Red Ribbon Week generally takes place the last full week in October, with the weekends before and following the last full week included as appropriate celebration dates. This year Red Ribbon Week will be October 20-28, 2012.
Red Ribbon Week is a way for communities and individuals to take a stand for the hopes and dreams of our children through a commitment to drug prevention and education and a personal commitment to live drug free lives with the ultimate goal being the creation of drug free America.
Red Ribbon Week began as a way to remember the ultimate sacrifice made by DEA Special Agent Enrique "Kiki" Camarena, who died at the hands of drug traffikers in Mexico while fighting the battle against illegal drugs to keep our country and children safe.
