A study recently published in the Journal of Alzheimer's Disease revealed that smoking nearly doubles the risk of the disorder. Led by Dr. Janine K. Cataldo, a US team from the University of California reviewed 43 published studies from 1984 to 2007. Combined with an analysis of 877 tobacco industry documents recently released to the public, they found that studies from researchers without tobacco industry affiliation demonstrated that the average risk of a smoker developing the brain disorder is 1.72, or almost twice that of a non-smoker.

Our appreciation, Dr. Cataldo and colleagues for your work in presenting the objective facts to inform and protect society. We look forward to the day that such harmful substances are replaced by activities that foster clean air and clear minds for all.
