I predict there will be a jihad against all pediatric cough formulations soon. The "safety uber alles" crowd smells blood after this victory and won't stop. They see danger lurking everywhere because they believe drug companies have to poison people to make profits.
Risk in life is not an all or nothing proposition. Life is a series of trade-offs, balancing the bad with the good, the bitter with the sweet, etc. Learning how to handle risky situations big and small is part of growing up, becoming an adult. We are infantilizing our culture further with this sort of overreach. You can't buy Claritin-D without a driver's license (but I can buy Viagra over the internet) build treehouses anymore, can't ride a bike without a helmet, can't play soldier, can't even sell cupcakes in school anymore without have some safety nanny get between you and a good time or you and a personal decision.
