In my opinion I think that they should do this because they are not only hurting themselves; they are making their unborn child addicted to drugs that they should not be addicted to. Come on if a woman is taking drugs while they are pregnant they do not need to have children in the first place.
Putting them in a rehab is not going to solve anything because when they get out they will fall right back into the same problem they were in before. Before you know it they will be pregnant again without regards to what the drugs are doing to the baby growing inside of them.
You cannot help those who do not want to help themselves. Therefore, if it is going to take drug testing them before and after the baby is born so be it. No one can say whether or not they are not going to use after the baby is born. Once you become an addict of drugs that is all you think about and nothing else.
The doctors are the ones prescribing this medication, and drugs except for what they get on the street. They are going to be right back in the line getting more so they can get their fix. They are not going to care what happens to the child and personally I do not think that a woman who is pregnant; doing drugs; and not paying attention to what is happening to the unborn child should be able to keep it after it is born.
Maybe it will be a wakeup call and maybe it will not be a wakeup call. It was their choice to do the drugs and put the baby in danger so they should buck up and take the consequences of their actions.
