Why is drinking, smoking, and drugs while pregnant so discouraged but abortion is so accepted?

Having fostered an infant that was born addicted to drugs I can tell you from that experience that a baby born to a horribly addicted mom is one of the saddest things you can see. And they don't get off of it overnight. They get methadone for extended periods of time. They are wired and they will keep you up long periods of time without sleep. I thought I was going to have a nervous break down taking on that whore's responsibility and getting that child well. That child today still has issues with her health and went through school with a learning disability. She is in junior high and struggles with adhd and add and an abundance of health issues. I think mothers that have children addicted should serve long jail sentences because they have condemned their children to a lifelong hell.
