I hate cigarettes, I hate the litter, the smell, and the smokers' belief that they have the divine right to pollute my airspace. I also hate the taxes I spend on keeping them in hospital - but. E cigarettes don't cause litter, the smoke is far less offensive. If people are going to smoke they will smoke. SF would be far better off banning actual cigarettes.
Btw, it’s counterintuitive and morbid to think about, but the healthcare and other public spending is actually less for smokers than nonsmokers on average: they tend to die right around retirement age before social security and expensive healthcare is needed.
