Last night a group of excited and vocal teenagers, with signs and banners in hand, demonstrated against tobacco. They marched across downtown Salt Lake from the Gateway mall and ended up at The Leonardo. The November 20th event was part of a national "Great American Smokeout" happening across the country. The event challenges cigarette smokers who are thinking about quitting to try not smoking for a day.

The BODY WORDS 3 exhibition currently on display at The Leonardo advocates against smoking simply by showing the effects of tobacco on the human body, specifically with the infamous "black lungs." The exhibit even provides a box where visitors can deposit their cigarettes or tobacco products on the spot.

The display also includes the famous American Cancer Society commercial by legendary actor Yul Brynner, recorded shortly before his death of lung cancer in 1985. "Now that I'm gone, I tell you, don't smoke. Whatever you do, just don't smoke."

It is said that smoking is the most preventable cause of death and disease in the World. An estimated 400,000 people die every year because of smoking - over 1,200 each day. And in most cases it's young people who decide to start smoking - 60% starting by the age of 14.
