No one can say it's 100% safe but it's a lot safer than lighting and inhaling smoke. In my opinion.
Been vaping for over four years and I'm happy with the results. So is my doctor even though he won't give his stamp of approval and recommend it to other smokers.
A physician can't recommend e-cigs because there isn't enough clinical evidence to support them as a therapy for smoking cessation. It's all about the healthcare "standards of practice," which requires them to only recommend therapies that have undergone the rigorous research required to gain approval under FDCA. E-cigs are outside the standards and represent too much risk to the medical community.
Example: Smoker asks physician how he can quit smoking. Physician recommends e-cigs. Patient switches and dies from cancer anyway. Patient's estate sues for malpractice because the physician didn't stay within the standards of practice. The same goes for other professions, including engineers, attorneys and accountants.
What he can do is discuss various options, including e-cigs, and present as much information as he has about the uncertainties as well as potential benefits, in an effort to promote good decision-making on the part of the patient. However,
you as the patient have to ask about it. He really can't volunteer it.
That's what my doctor did back in April. Paraphrasing, after I asked him about electronic cigarettes: "I can't specifically recommend them to you, but if you're serious about quitting, you should consider them as an option." He then went on a five minute explanation of what was known and what was still uncertain, and left the decision to me.
Sadly, a physician could prescribe Chantix or Zyban and have his patient give into the suicidal thoughts produced by those
nasty medications' side effects, and off himself. Physician would be immune from a malpractice suit because those are clinically tried and FDA approved therapies for smoking cessation.
Sucks, doesn't it?
