I tend to be a little more excited about. But I really like the idea of using something totally new and unique.
Addiction is a brain disease.
In fact, the structure and function of the brain changes when people smoke. Nicotine stimulates dopamine levels in the brain, which ultimately will change the structure and function. These increased levels of dopamine are associated with reinforced drug use. Depression is all wrapped up into smoking. We always find that smokers, as a group, are much more depressed than the normal population.
