A drug to help nicotine fiends will be used in clinical trials next year. A Maryland pharmaceutical company says it has developed a vaccine that would keep nicotine from reaching the brain. That would prevent the production of the feel good chemicals linked to addiction.

Health officials attribute the decline to education and lifestyle changes.
