Lard and Alcohol and drugs in products that are Kid-friendly?

Strange how in products that are universal like baked goods, candies, chewing gum and chocolates and confectioneries have stuff in them that can make them unsuitable for kids, vegetarians and for those who care about halal and kosher stuff. It's rather ridiculous. How are these things being sold universally when the majority of the consumers shouldn't and cannot even eat them? The type of gelatin if used must be mentioned, which is not. alcohol and drugs in candies and cholocaltes also must be restricted and mentioned. the fact that pork is even used in products like toothpaste is pretty harrowing. People keep on and on about animal cruelty and vegan and halal cosmetics, but has anyone paused to think about how this is largely ignored in everyday life items?
