This podcast offers a fairly well-rounded perspective on the vaping landscape and its history. The importance of regulatory bodies is well highlighted. The 'epidemic' of teen vaping addiction, despite the efforts of agencies, shows how problematic the bad actors in society are who act without an iota of conscience for their actions. The problem wouldn't be as bad if all actors involved in capitalism (from companies to retailers) resisted the temptation of an extra buck that could jeopardize public health, especially that of children. As James Monsees notes in the exit interview, it is perhaps the worst reflection of American capitalism.
While the physical health aspects have been discussed, the effect of nicotine addiction on the mental health of teens and adults has not been given enough attention. It is particularly more important given Leon ended the podcast with an optimistic note on the role of vaping in helping people move away from their cigarette addiction.
The way the podcast is concluded is of great importance, in my opinion. In the book "Thinking, Fast and Slow," Kahneman discusses the "remembering self" and explains that we are more influenced by the peak and end points, often overlooking the duration of the experience. I am not sure if this is a correct extrapolation, but IMO, a conclusion of teens grappling with their nicotine addiction would give a very different flavour to the podcast than the POV of vaping helping adult smokers.
