most of these come on lawsuits are frivolous but this one is not...
It's like the mesothelioma settlement stuff in terms of the lawyers going after any straw they can bend for a case. In the meso case, "if you or someone you loved....worked in ships, on ships, in factories, HVAC, plumbing et al decades ago you may have a case and can get what you deserve.
Of course, all these case topics are serious. It's how these lawyers troll for clients and the people who use them in most of the cases. The trolling for different medicine suits is even worse. They, and the FDA, are the reason why prescription medicine costs so much, IMO.
