re Tom Willis:  Says a study in Preventative Medicine says that smokers that vape smoke more often and smoke more cigarettes, not less.  That is one study I have to see.  I wish he'd have put an on-line reference to his statement.  The only recent study that was reported cite in PM was one based on a telephone survey to smokers, presented the smoker with hypotheticals of dangers or the two, and came up with conclusions.  So what you talking about Willis?  I'd like to see it myself.
