In The Dictatress and the Navigator (a live-action feature film I am writing, I want to direct myself, and I would like to play some characters within it) (I want to play both the Dictatress and the Navigator), one of the two protagonists is a dictatress. She makes a nicotine prohibition, or more accurately, a recreative tobacco prohibition (medical tobacco is fully legal) (medical tobacco means nicotine pills). What I mean is the anti-villainous Dictatress prohibits both smoking and chewing tobacco, and she hires many police officers for arresting people who sell recreative tobacco (nicotine addicts are immediately put in rehab). But, there are no tobacco cartels in the city-state she runs. Strangely, the Dictatress is against torture, and she only uses the death penalty for the vilest people (in other words, politicians who are both opposed to her and cruel even by her standards, cannibalistic murderers, and torturers).
The country of reference in my story is a Dominican Republic pastiche (if Dominican Republic were a city-state).
So, I wonder how could a nicotine/tobacco prohibition be efficient? Also, would banning nicotine be comparable to banning cholesterol?
