About 250 walked around the lake at Hagerstown City Park Wednesday as part of the second annual Walk in the Park World No Tobacco Day celebration.
The event was sponsored by the Tobacco Free Washington County Coalition.
The event is intended to counter efforts by the tobacco industry to get more people to start smoking, said spokeswoman Lynn Whitall. Coalition members are particularly concerned about allegations the industry is pushing children and teenagers into smoking, she said.
"Smoking kills and we want people to know that," said Whitall, who is the regional director for the American Lung Association.
The theme was "Raise Awareness - Not Funds." As people checked in at the four checkpoints around the lake they were given information about the dangers of tobacco use, she said.
