I plan to engineer a family of drugs to make the user unaddicted to tobacco, alcohol, cocaine, caffeine, or any other chemical addiction. Addiction bends a molecule pathway to a slightly different shape, which requires the non-bodily input from the chemical source. Making a drug to bend or train the shape back into place from the interior or exterior should be possible. Full restoration may require charged molecules.
Theoretical science, existential spirituality, sprinkled with elements of sociology, anthropology, transhumanism, and funk. [The technical explanation of funk is 'having major skill']
