Tingting Yao and colleagues here at UCSF just published "A content analysis of electronic cigarette manufacturer websites in China" in Tobacco Control. Here is the abstract:
Objective The goal of this study was to summarise the websites of electronic cigarette (e-cigarette) manufacturers in China and describe how they market their products.
Methods From March to April 2013, we used two search keywords ‘electronic cigarette’ (Dian Zi Xiang Yan in Chinese) and ‘manufacturer’ (Sheng Chan Chang Jia in Chinese) to search e-cigarette manufacturers in China on Alibaba, an internet-based e-commerce business that covers business-to-business online marketplaces, retail and payment platforms, shopping search engine and datacentric cloud computing services. A total of 18 websites of 12 e-cigarette manufacturers in China were analysed by using a coding guide which includes 14 marketing claims.

Roswell Park-Led Study Documents Significant Rise in E-Cigarette Use Among Youth in Poland
Cigarettes not replacing conventional tobacco cigarettes among this group, findings indicate
BUFFALO, N.Y. — Use of electronic cigarettes (e-cigarettes) has more than tripled among students in Poland, according to research led by Maciej Goniewicz, PhD, PharmD, a researcher in the Department of Health Behavior at Roswell Park Cancer Institute (RPCI). The study, published online ahead of print in the Journal of Adolescent Health, was conducted in collaboration with researchers at the Medical University of Silesia in Poland.
“Our research suggests that e-cigarette use is rapidly increasing among youth in Poland,” said Dr. Goniewicz. “This study adds to a growing body of evidence that e-cigarette use is increasing not only among adult smokers, but also among adolescents around the world. Further studies are necessary to illuminate our understanding of the reasons for this phenomenon and to help determine if e-cigarettes are a gateway to traditional cigarette use.”

Good for ACS CAN in calling out Governor Brown for taking $100,000 from Philip Morris. He should do what ACS asks and give the money back (and pledge not to take any more).
The reality is that neither Proposition 1 (which deals with a rainy day fund in the budget) and Proposition 2 (which is a water bond) have anything to do with tobacco. This is a bald effort to buy influence pure and simple.
Here is their press release:

ACS CAN CALLS ON GOVERNOR BROWN TO RETURN THE $100,000 CONTRIBUTION FROM PHILIP MORRIS TO PROPOSITIONS 1 & 2
SACRAMENTO – Philip Morris contributed $100,000 to Governor Brown’s ballot measure committee established to support Propositions 1& 2, and the American Cancer Society Cancer Action Network (ACS CAN) strongly encourages the governor to return those funds.

Almost the entire discussion of e-cigarette toxicity so far has focused on the fact that they expose users to lower levels of carcinogens (cancer-causing chemicals) than conventional cigarettes. At the same time, by design e-cigarettes expose users to nicotine in an aerosol of ultrafine particles that also have direct bilogical effects, particularly on the cardiovascular system and lungs.
Holly Middlekauff and collegaues just published an excellent review on the effects of nicotine and fine particle air pollution (from cigarettes and other sources) in the Journal of the American College of Cardiology that describes how these agents act on the sympathetic nervous system (which controls reflexes) in ways that increase the risk of heart attacks. While they note that there are not yet direct evidence on the effects of e-cigarettes on the sympathetic nervous system, they make a good case for being concerned until people show that such effects are not present.
The paper, "Adverse Effects of Cigarette and Noncigarette Smoke Exposure on the Autonomic Nervous SystemMechanisms and Implications for Cardiovascular Risk," is available here.

Lois Biener and J Lee Hargraves just published a nicely done longitudinal study that followed smokers in two cites for around two years and found that, controlling for level of nicotine addiction and demographics, intensive e-cigarette users (defined as using e-cigarettes daily for at least a month) were 6 times more likely to have quit smoking (defined as not smoking for at least 30 days) than smokers who did not use e-cigarettes.
They also found that intermittent e-cigarette users (defined as people had used e-cigarettes more than once or twice, but not daily for a month) were no more or less likely to have stopped smoking than non-users, but were were 6 times more likely to expect that they would still be smoking one year into the future.
There was not much difference in the motivations for using e-cigarettes (Table 3 of their paper), athough there was a suggestion (p=0.08) that the intensive useres were using them because of health concerns compared to the other groups. This may explain why the intensive useres were more successful at quitting smoking. It may be that the intensive users were replacing cigarettes while the non-intensive users were not.
