One hundred Jeffco students spent their Friday morning kicking butts. The cigarette variety, that is.

The students from Wheat Ridge High School, Everitt Middle School and Pennington, Stevens and Vivian elementary schools took part in the Third Annual Wheat Ridge Cigarette Butt Pick-Up at two local parks. Cigarette butts, which contain multiple toxins and are not biodegradable, are one of the top litter items on the country’s roadways and in its waterways.

The event, rescheduled for Friday after bad weather on April 22, was meant to raise awareness about the harmful environmental and health effects of tobacco. It included booths with information about the effects of tobacco on the planet and how tobacco companies target youth through advertising and promotions.
