No one on here defended meth use. We all see a HUGE problem with drug use (including alcohol) during pregnancy. The only question is what is the best way to have FEWER addicted babies. I don't think charging them with manslaughter helps, not unless there are treatment options and manslaughter is reserved for cases where someone can PROVE reckless, continuous and damaging use, and even then I'm not sure what we accomplish by jailing that mother for perhaps 10 years. We fill a prison bed, which is nice, and get sweet vengeance, but we've got prisons full of drug users and use and abuse of illegal drugs hasn't seemed to slow a whole lot so long sentences don't appear to be an effective way to lessen drug addictions and the problems that come with it. That's what the evidence suggests. And I see no reason why long jail terms would work better with pregnant women than it does with all other addicts.
And I brought up wine because in my world, the addiction of choice is to alcohol and I see far more women with drinking problems or who have admitted to abusive drinking while pregnant than I've seen addicted to meth. The ones I've talked to didn't need a 10 year jail sentence, they needed treatment for an addiction. And frankly, while the woman is pregnant, if treatment (for alcohol, meth, heroin, cocaine, oxy, speed, etc.) doesn't work, and it often does NOT work, I'm OK with incarceration to protect the child, except it makes more sense to lock them in a treatment facility than an ordinary prison.
