Nicotine present in tobacco has been used for its medicinal value for quite some time for diseases like Parkinson’s disease and ulcerative colitis. A study from University of Miami School of Medicine, USA revealed that people from families prone to Parkinson’s disease are less likely to develop the disease if they drink coffee on a regular basis.

Both coffee and nicotine have a link with dopamine in the brain. Dopamine is a chemical that decreases in patients with Parkinson’s disease.

It is possible that people who are going to have Parkinsons disease have lower levels of dopamine. Those with low levels of dopamine may be more likely to enjoy caffeine.

Parkinsons disease occurs when brain cells that produce dopamine die. This is a progressive disease and affects about 1% of people above 65 years of age. Symptoms include tremors, muscular rigidity and slow movements and can progress to paralysis. While there is no cure, some drugs may make symptoms better for a period of time.
