Insurance companies have limited the extensive testing that used to be performed at physicals. Most check the basics, looking for sugar, cholesterol, triglycerides, liver function, uric acid, etc.
I have black coffee (several cups) before my physical and usually vape and smoke a cigarette or two by that time with no comments other than I need to get triglycerides down under 200. Those have been high in the past and I'm doing good to keep them below 300.
I carried my Ecig in a year ago and demonstrated it in his examining room. He was impressed, took some printed articles, read them, did some research, and approved of ecigs as a quit smoking vehicle. A couple of weeks later he put a display with pamphlets about ecigs in his waiting room.
Find a doctor who actually researches things like that and change if he doesn't think ecigs are better than tobacco.
