In a previous blog entry, I mentioned knowing what is in your E-Juice, as some substances in your E-Juice could prove to be devastating to your health. Recently there has been quite a stir in the electronic cigarette community regarding the chemical known as diacetyl in E-Juices. Diacetyl is an FDA approved substance that gives a buttery and creamy taste to substances. When ingested it is safe, in fact many of the foods you buy at the grocery store (especially the ones with artificial flavoring) most likely has diacetyl in it. However, when copious amounts of diacetyl is inhaled, it can severely damage your lungs. Long term exposure to diacetyl via inhalation can cause something called obliterative bronchiolitis (also known as popcorn lung) which is a rare syndrome that hinders respiratory function. Obliterative bronchiolitis is when the bronchioles in the lungs are being compressed and narrowed by scar tissue and/or inflammation. Symptoms include severe shortness of breath, wheezing, and coughing. What is so scary about this disease is it is irreversible, and the worst cases of obliterative bronchiolitis would result in lung transplant.

The truth is that there are major advantages and disadvantages of both surveys and clinical trials to examine the potential benefits of electronic cigarettes. Both types of study designs have inherent biases which can produce results that are more "favorable" or "unfavorable." This is why the methodology of published research needs to be examined so carefully. It is not so simple as to dismiss RCT evidence and accept survey evidence. One needs to consider the strengths and limitations inherent in both approaches. And at the end of the day, the only defensible approach, I believe, is that both types of studies are necessary, and we must carefully interpret and synthesize the findings from studies of multiple designs, using the totality of the evidence to make final judgments about the benefits of electronic cigarettes.

As vaping becomes increasingly more popular, I am seeing more and more vendors throw around the word “premium” on their line of flavors. How their line of E-Juices only using premium flavoring, and it is the best on the market. I’ve also seen E-Juice manufacturers charge a whopping $1/ml for a bottle of E-juice; that’s $30 for 30ml worth of E-Juice. But what exactly are you paying for What justifies the price of such high price E-Juice Why pay $30 for 30ml when you can buy a 30ml bottle for $10 elsewhere Is it just a fad a gimmick or is there really a noticeable difference
