Fortunately with the advent of the internet, other effective (non-invasive) methods are sure to be spread. So the information about how to end a pregnancy with common plants will still be available, no matter what. Including step-by-step instructions. Of course, poisonings are VERY possible this way, too, since many of them can cause a nasty shock to the system, and dosage can be variable according many factors.
For instance, Google "abortifacient herbs". http://www.google.com/search?q=abortifacient+herbs
Pomegranates. Not eating the fruit. Eating the rinds, seeds, etc. Animal studies show it to be effective.http://en.wikipedia.org/wiki/Pomegranate
Or Tansy. Tansy seeds are available, though these are not native to America. Classical use.http://en.wikipedia.org/wiki/Tanacetum_vulgare
Or a lot of other things....
I would rather they turn to something like the 'morning after' pill, even compared to 'the pill'. Better only to be on a med when you need it, than always be on meds, whether you need them or not.
But in a pinch, with the clock ticking and NO OTHER OPTION, it would be better to find relatively safe, effective, natural abortifacients and spread the most 'fool-proof' recipes (along with overdose symptoms), than have no other way out besides suicide.
Though removing ALL social stigma from pregnancy and changing society to better take care of unwed mothers and babies would be even more preferable.
Wouldn't it be nice if young women could carry a baby to term, and not be made a social pariah? Even raise them without it 'ruining their lives'?
Unfortunately, the many of the same religious people who decry abortion want to JUDGE those women, too. Make the world HELL for them. They want to force them to carry a baby to term, then live with the consequences, with no support. After all, under-educated, drop-out, impoverished women will flock to the church for their 'help'.
