The opposite is true. Most Americans are eating food that isn't what the label says it is (eg. fish). This sort of scam is completely legal and the FDA allows it to happen. More regulation needed.
Then you have dietary supplements which is a complete wild west. There's a 3 billion dollar kratom industry, for example. You can buy this dangerously addictive drug at your nearest 7-11 or gas station.
So how many people have been seriously harmed by this 3 billion dollar industry? I'm particularly interested to know how many people who weren't taking the drug but were harmed by someone who was?
I don't have figures because nobody has done the studies. Like I said... Completely unregulated.
R/quittingkratom has tens of thousands of members. So hundreds of thousands of people have had their lives seriously affected by it (every addict ruins multiple lives... Family and friends). That's to say nothing of the many dead from kratom.
If there are no studies and you're implying that kratom is a big problem, so what are you basing that on?
There are many subreddits related to quitting various things. If that's your metric for “lives ruined" there are dozens of other things that have ruined dozens of times more lives.
I mean, if there are hundreds of thousands of posts from Americans talking about how it's ruined them, how the hell are you going to respond with "show me the studies"?
