If the research from this study holds up, the people who make nicotine patches just found a whole new client base: Nonsmokers.

A new study out of Vanderbilt University in Nashville, Tennessee found that when nonsmokers wear nicotine patches, it can have two effects. First it improves their memory. Second it helps them drop a few pounds.

The researchers believe the memory part could be a huge step in battling dementia and Alzheimer's disease in older people.

In the study, they found that six months of nicotine patch treatment restored long-term memory in about half of a group of people in their 70s with mild cognitive impairment.
