1 hour? Is there a summary somewhere?
Edit: Never mind one of the commenters gave a brief summary as follows:
There are many subtopics covered in this lecture. The TL;DR on the topic of health risks caused by e-cigarette use is: While it is not precisely possible to quantify the results of long-term use (until more time has passed for actual use cases to be measured), data that is currently measurable such as the presence of certain bio-markers between e-cigarette users/smokers/non-users support the claim that
vaping carries 5% the harm of smoking.
This presentation is not the result of an original research study performed directly on e-cigarette users and does not generate any new medical data itself, but rather consolidates information about research studies performed to date and other statistics about
vaping, then compares those against the common public perceptions about vaping risks/benefits.
