But the marijuana plant may not be the only plant that could offer hope to people with chronic disease. Research studying nicotine suggests that it may have a medical benefit in patients with neurological disease like Alzheimer's.
If so, the use of nicotine as a treatment would challenge conventional thinking that ties the chemical to cancer and heart disease causing cigarettes.
Separating nicotine from smoking
More than 20 million people have died from causes related to smoking, according to the Surgeon General's annual report on the health consequences of smoking.
An intense focus on educating smokers in the risks of the disease has substantially reduced the number of cigarettes purchased in the U.S. over the past few decades. That's great news given that smoking causes 87% of lung cancer deaths, according to the Surgeon General.

But evidence suggests that nicotine, a stimulant chemical found in tobacco, may have some medical benefit -- just not when smoked as a traditional cigarette.
In a study conducted by Vanderbilt University's Center for Cognitive Medicine, Dr. Paul Newhouse found a link between nicotine and improved brain function in elderly patients with mild cognitive impairment, a potential precursor to Alzheimer's.
