nicotine
Smokers have notably lower incidences of Alzheimer's disease than their non-smoking counterparts. Nicotine mimics the action of the neurotransmitter acetylcholine, a dearth of which is the main cause of this disease. It is believed that this effect could also help sufferers of other neurological disorders, such as Parkinson's, Tourette's,ADHD and schizophrenia. Even depression had been targeted as an area which nicotine could prove useful.
Diabetes is another area where nicotine offers potential transformative effects. The chemical has been shown to improve the growth and health of blood vessels. Diabetics often struggle with blood flow to their extremities and medical scientists are trialling a nicotine-based gel to combat this.
