Yes, most of the people who participated in the survey heard about it through ECF or through Facebook. Not a random population sample.
The survey participants' extremely high rate of getting off traditional cigarettes -- substituting vaping for smoking -- underscores (in my mind) the importance of having a wide variety of devices and wide choice of flavored e-liquids to suit each person's needs or preferences. And the importance of becoming aware of the variety....thank goodness for ECF!
Indeed, Dr. Farsalinos stated on pages 4368-4369 in the Discussion section of the results:
It should be emphasized that participants in these surveys are mostly dedicated users. Herein, this is
verified by the fact that the majority of subjects heard about this survey from EC users’ forums. It is
expected that such a population has more positive experience from EC use. Other subgroups such as
people who were using ECs in the past but are no longer using them, due to either failure to reduce
smoking or negative experience and side effects, are not motivated to participate to such surveys.
.
Therefore the results should be interpreted with caution and cannot be extrapolated to the general
population. The 81% of participants reporting complete smoking substitution cannot be interpreted as
the true potential of ECs in smoking cessation in the general population; controlled studies have found
much lower cessation rates [9,10], although such studies cannot take into account the large variability
of products available in the market which gives users the opportunity to choose devices based on
personal preference.

I would suspect that when e-cigs were provided to people in older studies, the devices generally were cig-alikes, rather than the robust types of personal vaporizers used by a great many of this forum's readers. They also probably used tobacco flavors, rather the wide variety of flavors that adults who vape can choose from.
No wonder experienced vapers reported far better quit/substitution/reduction rates than have been seen in older studies.
