You asked me how you tell the difference between self induced abortion and miscarriage. Well, how do you tell the difference between the accidental bathtub drowning of an infant and murder? My guess is that in both cases, it's so likely that happened was really an accident that there's no point in investigating it. Unless there is some extraordinary reason to think the mother (or someone else) is at fault for the miscarriage, why look into it? If a woman wants an abortion she's going to keep her pregnancy private to begin with.

I'm not sure what I think about the drinking/smoking thing. Is it currently illegal to smoke in the car with kids? How dangerous is alcohol and tobacco to developing fetus? If it was extremely dangerous to have even one drink (which it's not) then yeah, I'd say it should be illegal to drink while pregnant.

Do I want women who have abortions to face life in prison? No. I believe intent matters, and I give people the benefit of the doubt. I sincerely doubt that many women who have abortions really believe they are killing people.

There are difficult questions that would have the be hammered out if abortion was ever made illegal - I'm not denying that. I just think any commitment to human rights requires it. Still, the goal is not to use the government to prevent every single abortion at any cost. The same as with anything that's currently illegal. Our judicial system is supposed to be stacked heavily in favor of preventing the conviction or harassment of innocent people.
