The reason is that we work on "evidence based practice". That means that until there is a study proving we can't be sued for divulging information, we keep our trap shut on our personal opinions. One lawsuit can ruin a career and quite frankly, it isn't worth it. Since there are no studies and the effects of long term vaping are unknown, you aren't likely to get many to go on board. If the patients would stop suing, we would be much more willing to use you as our experimental subjects. I VAPE because I BELIEVE it to be better than smoking cigarettes, but if I were to recommend it to you and you had an allergy to whatever you could then sue me for your bad reaction and promoting an unproven cessation device. Until it is "approved" by our facility, you won't see us putting our necks and livelihood on the line. There are some hospitals that do allow it in the units, and some forbid it within their walls.
Sorry, that is the hard facts. Society is too litigious. Get people to stop suing us for trying to help you and we would.
To the student who is reaching out to patients without a license, I applaud you for your efforts. I also warn you to get some good malpractice insurance and read your coverage very carefully.
What people who sue without good reason fail to realize or care about is their behavior forces doctors to be less then honest and forthright with all of us because of their fear of being sued. I woke up during surgery and only found out about it because the post-op nurse let it slip. My surgeon, who is very good at what he does, never told me and I don't blame him because I'm sure many patients would sue the hospital out of business if they were told. I believe in suing when there has been malicious, purposeful harm or negligence, but not when an accident happens or for every little innocent mistake made. I was sent home from an ER and told I had a stomach flu when in fact I had a complete intestinal blockage. My family doctor insisted I go back to the ER where I was admitted, but it took them three more days to finally make the right diagnosis and perform surgery. By that time, I was in the beginning stages of sepsis and part of my intestine was necrotic. I could have died from being misdiagnosed and I certainly could have sued, but I didn't. The doctors and nurses were all trying their best, they just missed it. I think we are too sue-happy as a society and instead of making doctors better at their job, it makes them afraid to be honest and sometimes too cautious to try new promising treatments.
