Honestly, most of them CAN'T comment on it professionally, it's not FDA approved, they put their practice and their license up for lawsuits if ecigs are proven to be unsafe. Dr Antifreeze really knows better...he just SAID that to make you drop the subject...he didn't want to discuss it, if he had appeared to condone it in any way, when your aunt passes, someone could say "well she wouldn't have dies so quickly, if dr. Antifreeze hadn't started her on e-cigs!". And trust me, some slimy attorney would take the case, if for nothing else than to get a "shut-up settlement"...
