I should have clarified this earlier.
All of this is from "Neuropharmacology: From Cellular Receptors and Neurotranmitter Synthesis to Treatments for Neuropathology & Drug Addiction" by
Daniel J Calcagnetti, Ph.D. (daniel @ fdu.edu)
In dealing with dependence (addiction), there are two ways to look at it
Psycholofical vs physical
Physical dependence is when the body has adapted to function in a stable manner only when the drug is onboard.
Use of desired drug would stop physical phenomenon (in your case the shaking you described)
Psychological dependence is a measure of thought compulsions about the drug at all times when the user is not taking the drug.
This refers to all drugs, not only tobacco.
What I addressed earlier is a new type of dependence that is being investigated. Some call it co-dependence, others call it syndergy.
I myself am not a smoker. I tried half of a cigarrette in highschool where I promptly coughed up a lung like a little girl - but give me three beers
or more and I feel like lighting up. It is this phenomenon that perhaps the action of one drug (it could also be the second hand smoke) changes
neuronal processing for secondary drug usage - the so-called gateway drug (which term I hate using since it is so often misused)
Furthermore there is also cross-dependence that is related to co-dependence. Some drugs are able to suppress, elivate or reduce the effects of
another drug that can produce dependence as well. This is like trading a greater evil for a lesser evil. Examples include giving a person suffering
from alcohol some valium in order to reduce the effects of alcohol, or by combining alcohol with coc aine (stimulant and depressant yields
effects that can be found online but cannot be posted here due to forum policy)
