How about the ingestion of nicotine, an extraordinarily potent and beneficial anti-viral chemical?
Could the threatening of the multi-gajillion dollar medical industry have absolutely anything to do with the demonization of tobacco? Let alone the stimulating and calming effect on people that politicians want to be stupified and anxious? Let alone the fact that there are literally hundreds of chemicals, a great many of them carcinogenic, in tobacco additives and tobacco paper which are completely uninvestigated because those additives are considered "trade secrets"?
It's not the tobacco and it's not the nicotine that kills you. They keep you awake, calm and free from many viruses and other nasty bugs.
It's the additives.
And many of them are required by the same government that demonizes them.
