Controversial Study Suggests Smoking May Have Neurological Benefits for Parkinson's Patients.

A new study shows that people with Parkinson's disease who smoke cigarettes are less likely to die of neurological problems than non-smokers, but Parkinson's smokers were found to have a higher risk of death due to related smoking-related complications such as lung cancer. The study supports the idea that some ingredients in cigarettes might have neuroprotective properties that could be explored in future research. However, the scientists stressed that the potential benefits of smoking cigarettes in Parkinson's do not outweigh the substantial health risks of smoking.
