Telling people lies when it comes to health isn't protected by the first amendment. People think the first amendment is this vast catch all and you can just say anything but it's really not. You really can't just say anything you want. A example of speech that's not protected is fraud, so if I make a website or blog that looks legit and it says drink bleach for magic powers that wouldn't be covered under free speech, or telling someone to kill themselves isn't protected either. The first amendment isn't really that broad when you get into the nitty gritty
