I'm fairly libertarian so I'm going to say, that's fine. As long as the correct / max dosage is noted on the label/instruction sheet (don't know about US, but in Slovenia, pretty much every drug, even common ones like Aspirin, come with detailed instructions), I don't really see the need to excuse people from being responsible adults (with possible exception for opioids and other addiction-prone drugs).
