Not everything wrong is a matter for lawcourts. I think most women who lose a baby and put it down to the fact that they had drank and smoked heavily during pregnancy would recognise that they had been wrong to do so.

There seems to be a tendency to oversimplify - if something's legal, that means it's right; if something's wrong, it ought to be illegal. But that's essentially fundamentalist thinking, at home only in set-ups like the Taliban's Afghanistan or John Calvin's Geneva. I think we have to muddle along in a world where often enough bad things are going to be legal and some good things are going to be illegal.
