Just to make sure this list isn't cherry picking, have you come across any studies which show inconclusive or negative results with regard to safety?

In this section. the 'Sucking' riverside study was included as it relateds to e-cigs. This study did indeed suggest potential negative health effects from 'sucking' on e-cigs. As I commented on Dr Siegels blog when the study came out, IMHO it seriously misunderstands the nature of e-smoking and any health effects. They seemingly confused nicotine delivery in e-cigs and the increase inhlation people use when smoking lite cigarettes.

AFIK there has been no attempt to chery pick. If you find a study that is adverse then it is worth posting. This ensures that if there is a problem then people are made aware of it, can study the effect and/or correct mis-information.

This was posted elsewhere on the forum....

Of interest is this development presented in a 2010 Swedish study, Common Household Chemicals and the Allergy Risks in Pre-School Age Children

We propose a novel hypothesis that PGEs in indoor air exacerbate and/or induce the multiple allergic symptoms, asthma, rhinitis and eczema, as well as IgE sensitization respectively.

PGE - propylene glycol and glycol ethers.
The issue it raises and the inclusion of PG within the hypothosis they propose, does seem at odds with other studies on PG.

Over at Frank Davis' blog there is an interesting comment on a recent study into Nicotine and Smoking --> Smoking Boosts Brain Power

Although the article title refers to Smoking, one of the key findings of the study is about Nicotine. It is a Danish study and the abstract (useing google translate) is available --> Meta-analysis of the acute effects of nicotine and smoking on human performance

The conclusion says

Conclusions

The significant effects of nicotine on motor abilities, attention, and memory likely represent true performance enhancement because they are not confounded by withdrawal relief. The beneficial cognitive effects of nicotine have Implications for the initiation of smoking and maintenance of tobacco dependence.

Frank's article give more background and also further studies and information.

This is quite a beneficial finding wrt to e-cigs (pv. eni, electrofag et el) as the study seems to suggest that nicotine has benefits which aid performance.

It might be useful to add the studies I found and posted here about how nicotine by itself isn't especially addictive, but in the presence of MAOIs (of which there are several in tobacco smoke) it becomes significantly more addictive.

I'm a bit wary of scientific studies. There are many many cases of scientific theories proving to be unsatisfactory - from geocentrism to crystalline spheres, to humorial medicine, to ether theory etc etc (The list, according to some, is endless!).

Now that's not to say we should ignore science, but even the most ardent scientific realist claims only that science delivers approximate truth, albeit that this truth gets 'truer' as time goes on. But there are cases where science has just got it completely wrong. Given what is at stake, I would like a full, informed and sensible debate (ending with a liberal recommendation that we can vape if we like - after all, smokers can smoke if they like...) and only hope that the vested interests can be kept at bay...
