Though e-cigarettes gained a fast following, the number of people using them isn't increasing. So why has the U.S. government started spending taxpayer money to undermine them as a tool for smoking cessation and harm reduction? And why does the U.K. endorse them?

The EPA is evaluating 10 chemicals under the Lautenberg Chemical Safety Act. To guide their decision-making, we have created explanations for each, with recommendations when the science is clear. Here is the science story on Pigment Violet 29.
