And could it be compounded by the fact that tobacco smoke has monoamine oxidase inhibitors, which means that the breakdown of those neurotransmitters is inhibited?
Neurochemical adaptation.
There are dozens and dozens of chemical processes inside the brain that are affected by smoking from the action of neurotransmitters to chemicals that mimic the action of morphine inside the brain. These chemicals actually alter the way a person thinks, feels and acts. As a person smokes (or take other drugs) his brain adapts to being in that altered state.
This goes over and above what people classically think of as addiction.
There is a physical addiction where the body adapts to being given a certain amount of the offending substance. This changes the heart rate, the way the organs and digestion operate and, when withdrawn, will cause PHYSICAL symptoms of discomfort and pain.
There is psychological addiction where people become used to using drugs as a crutch or escape mechanism. When they feel anxious or have other negative feelings they learn to turn to drugs to make them feel better. Upon withdrawal, the reality of life's problems begin to return, causing panic attacks and emotional problems.
Neurochemical adaptation (or neurochemical addiction, if you will) is a third, lesser-known facet of addiction that can take years to overcome. A person can overcome physical addiction in a period of weeks or months. Psychological addiction can be overcome with psychotherapy or group therapy like A.A, et. al. But neurochemical addiction can hang on for extended periods of time. It will actually alter the way a person thinks, feels and acts and he will not normally be conscious of his own behaviors. He will actually be drawn back to drug-taking behaviors as a form of "self-medication" to overcome his perceived sense of dysphoria born out of neurochemical drug withdrawal.
It is not unheard of for neurochemical addiction to take ten years or more to resolve.
