Ending the commercial sale of combustible tobacco products is not the same as prohibition. It is analogous to the way jurisdictions are looking at cannabis “legalization” or “de- criminalization”. In jurisdictions that have “de-criminalized” cannabis – no one is arrested for carrying it or using it (within prescribed limits), and no cop is going to search your car on the suspicion that you have cigarettes. The public would be free to grow their own tobacco, give it as gifts, and even bring it in from other places.
In jurisdictions that have or are considering “legalizing” cannabis, no one is in favor of selling cannabis as a typical consumer good or making it available in convenience stores, gas stations, and the typical retail environment. Ending the commercial sales of cigarettes is not meant to make tobacco illegal, it is merely a rational response to the damage caused by the current extensive availability of cigarettes.
