Well you probably should spend more than 5 minutes reading the thread, but I'll reply to this anyway.
A major point of this thread has been the irrelevance and illogicalness of the argument that "a woman should be able to do what she wants with her body." That's what an English teacher would call a straw man fallacy - it implies that the other side disagrees, when they do not. There is no one on the pro-life side arguing, "No! Women do not deserve control of their bodies!" The argument is that an unborn life is NOT the woman's body but rather a separate person and as such deserves the right to life. It doesn't make sense to discuss any other point in regards to abortion. The pro-choice and pro-life sides both need to drop their straw men arguments and address the real issue: is the unborn a distinct, separate person deserving of basic human rights?
I agree with you on drugs - I don't choose to use them either and personally I think pot is kind of gross (the smell just makes me nauseous and gives me a headache, can't stand it), but I don't think that's reason enough to have it be illegal. From the pro-life stance, however, this is not at all equatable with abortion; in abortion, a life is being taken. I agree that a person should have the right to control their own body, but there have to be limitations on that - we have to limit rights to behavior that doesn't infringe on the rights of others. The abortion debate hinges only on whether or not the procedure infringes on rights that the unborn should have protected. It is a far simpler issue than it usually portrayed as.
And not having an abortion is not enough. As I've said elsewhere, what if people had said in the 1850s, "If you don't believe in slavery, don't own slaves"? Nothing would have changed. The protection of human rights is dependent on groups of people imposing their beliefs on those that would violate said rights.
I have to ask this, though: why do you think abortion is bad? If you believe the unborn is part of the woman's body, how is abortion different than killing a tapeworm or removing a tumor? And if you think it's bad because it is taking an innocent life (as I do), how can you defend the right to take innocent life at will? I see this claim all the time, "I don't think abortion is good personally and I wouldn't have one, but I'm not going to impose that on someone else." That doesn't make sense, unless you also want to adopt a purely relativist stance which would require you to permit anyone to do anything as long as they felt it was ok.
