As an Iowan, this reminds me a lot of the bill that's been pushed through my state's senate twice now (as recently as last year), which would prevent Iowans from filing lawsuits against pesticide and herbicide companies if those companies follow the EPA's labeling guidelines. The bill passed the senate both times, only stopped because the house declined to take it up.

For context, Iowa has the fastest growing rate of new cancer diagnoses in the country, and the second highest overall cancer rate.
