Putting prices up too far would merely increase the amount of cigarette smuggling that would take place. It would be a godsend to organised crime gangs here and overseas.
Using big hammers to break small nuts is counter productive. Many Asian countries have draconian measures to discourage drug smugglers. In Malayasia and Indonesia they execute them but, as we know from the case of a British woman condemned to death in Indonesia, the big boys, in this case also British, who organised the smuggling ring, got away with it, presumably they bribed or blackmailed the right people. It is the silly woman who was so easily duped to carry the drugs that is quite, literally going to get it in the neck. It certainly hasn't stopped drug smuggling
We would end up with most smokers smoking smuggled cigarettes, our prisons full of cigarette mules who we know are either desperately poor people prepared to risk everything for money or silly dupes like the woman in Indonesia. Tax revenue would drop and smoking related medical problems would remain.
