Are all of these ingredients equally harmful? If not, why not just ban or restrict the ones that are harmful and keep using the rest of them? It's sort of weird to bundle a lot of very different types of chemicals under the same term.
These novel ingredients keep getting banned for negative health issues like causing cancer, new variants keep getting introduced to the public, the new variants keep getting banned doe being harmful, repeat ad infinitum.
The public are not lab rats to be experimented on using these artificial ingredients so that companies can make money.
