Swings and roundabouts aint it. I've known 100's of heroin and/or crack addicts have their children taken off them at birth but i've known a handful, and it is that, a handful make a change for the better. All this woman is doing is offering up a solution much the same as projects that offer substitute medication for addicts, be it Diamorphine (as they have in Scotland), Methadone, Subutex or Antibuse for alcohol users. Its just a different take on an age old problem.
Millions of children are born with a habit and they have to go through the same detox as adults but its easier in some ways with children as no one ever dies from a 'cluck'. The same unfortunately cannot be said for alcohol.
Also as a thought Alan Turing the fella who was instrumental in providing a formula for the concept of algorithm's was chemically castrated because he was gay and subsequently killed himself. The man was a genius and because of his sexual orientation lost his job etc etc.
