Re: Medical Community - "Not Invented Here"
"The Medical Community", from what this uninvolved layman sees, considers "Patient is addicted to nicotine" as the problem, from the harm-prevention point of view. Transition to vaping sometimes comes with giving up smoke, sometimes doesn't, but, leaves the patient addicted to nicotine. "The Medical Community" considers a "cure" as the preferred solution in most cases - you get to close the record instead of the doctor eventually retiring and handing on the patient's problems to their new doctor. Anti-smoking schemes and nicotine replacements are offered as short-term aids to permanently quitting - or not quitting. This may be right or wrong.
Addiction to clean bottled nicotine (used in some Agatha Christie murder stories, which may or may not be realistic, it makes for variety from cyanide or please-stop-using-our-brand-name-to-kill-people sleeping tablets) may be healthier than inhaling burning leaves, but, wouldn't you rather not?
