So? I'm pretty sure that a ton of people eat foods that are also causing cancer, yet nobody bats an eye. Barbecue anyone? Yes this causes cancer as well, and you get exposed to a lot more smoke that you would by sitting directly next to me while I smoke. Also, vaping has been shown to be 95% safer than cigarettes, so there is nothing wrong with that. More vape, but less damage.
What is ever worse, is the amount of people that are not aware of the benefits of e-cigarettes. I hardly doubt that anyone here will read more than a single page of the report though.
