Prescription-only Tobacco is the Sensible Solution
I believe that like other drug addicts, tobacco users must be acknowledged as being sick people and treated accordingly. And like other dangerous drugs, tobacco should be controlled and available on prescription only. People with tobacco addictions would be required to register through a medical professional and be prescribed appropriate amounts of tobacco for their personal use. They could even specify which brand and delivery mechanism they prefer; Port Royal pipe tobacco, Winfield blue cigarettes or whatever. They could obtain their tobacco by bringing their purchase authorisation (perhaps something like the photo drivers' licence) to a chemist or some other registered outlet and obtain a week's supply at a time.
