Longtime smoking cuts Parkinson’s risk dramatically

It's a catchy headline – smoking cuts Parkinson's risk dramatically – and it appears to be true, but researchers at the National Institute of Environmental Health Science don't want you to start smoking.

Honglei Chen, a tenure-track investigator at the Institute. "It’s important to make that very, very clear."
The study, released today in the journal Neurology looked at the lifetime smoking history of more than 300,000 people, and confirmed the inverse relationship between smoking and Parkinson's disease, established in earlier scientific studies.
