One also needs to be quite careful about confusing features of certain demographics (families with complex problems are likely to have a parent who smokes) with the converse (not all parents who smoke have families with complex problems).
How many times have I said that there are exceptions (like all statistical data) to the statement: "Mothers who smoke while pregnant are more likely to tick boxes that will form the basis of eligibility criteria for wider state-run "good behavior" and intervention programs" ?
One should likewise not confuse "parents who smoke" with "mothers who smoke while pregnant". I'm going to again assume that the latter has a more troubling profile than the former, without even googling.
You like this program because you say it saves the NHS money. I disagree/think its besides the point because of my philosophical objections but also because once the baby clears this hurdle she's still statistically at risk; she's more likely to be eligible to whatever other programs the state decides to roll out, like paying parents to have their children exercise or eat properly (I'm sure some clever bureaucrat could make a case for this). In other words, this is a slippery slope.
And of that subset of smoking pregnant women who don't meet the problematic criteria that I've been speaking of; the baby is born healthier, and they go on to lead lives that are less draining on the NHS - they're irretrievably co-mingled with the others, it is impossible and unethical to identify them, and it would make no sense to even try.
I see that you have implied that my diet coke addiction is not actually an addiction because it is not a physical one. You do realize that you're treading on hallowed ground for the woolly-headed?
