In fact, the subjects had no idea that they were part of an experiment involving artificial manipulation of their news feed for the purposes of potential inducing happiness or sadness as part of a research study. This potential use of their Facebook account is simply not mentioned in the Data Use Policy. The policy states that the information provided by users may be used for research purposes. It also states that the information may be shared with outside vendors to conduct research. However, nowhere does the policy state that users agree to intentional manipulation by Facebook staff for research purposes.

There are some specific problems with survey studies that could lead to an overestimation of the benefits of electronic cigarettes. One major problem is that a survey study of the use of advanced vapor products would result in a severe bias towards finding a high level of effectiveness of these products. The reason? By the time smokers advance to use products like open-ended systems, they have already experienced success, fulfillment, and enjoyment with vaping. In other words, limiting the sample to users of advanced vapor products filters out the majority of e-cigarette users, who do not experience great success and therefore don't go on to the more advanced products.

This seemed surprising at first as the current trend shows the high the PG level the more of the three chemicals that will be released. However a reasonable explanation would be the flavoring used in the 50/50 ratio E-Juice. E-Juice flavorings (especially the low quality type) can be alcohol based thus the increase of acetone being released. Capella and The FlavorApprenticeare two companies that avoid acetone in their flavoring solutions. Sonot all E-Juice have to have acetone.
