Why in the world would Amazon want to sell an item and say can be ingested, when it clearly has ingredients that can cause cancer. Wish every state would wake up like California and ban all these cancer causing things.

Love the chips, nice 100 +/- calorie snack, reminds me of Munchos, but less greasy, flavors are good (salt & vinegar least favorite). And they've started shipping APO--thank you and my family thanks you (so they don't have to get the package and reship!) Made my day.
