There's no way to be 100% sure if a product harms a human being unless you try it out on a human being, and that's where suicidals come in :F I think that they should test medicines on human that want to rather then animals.
Well, I'm going to pro/contra here (you should ALWAYS do this, even if you really hate something, you should always try to look at things from another side of view)
But, well, I'm going to argue with myself here (yes, I'm crazy)
Pro: Animals get slaughtered anyways, so why can't we test medicines on them instead of eating them?
Contra: If animals get slaughtered, we know what'll happen, the animals get a short pain or no pain at all, but with medicines, you never actually know what'll happen, it might suffer to death.
Pro: Yes, but we don't want that to happen to humans, do we?
Contra: Yes, but it's not because it happens to animals that'll happen to humans and virca virca.
Pro: True, but there's a high chance it will. So you're actually suggesting that you'd rather test out those products on humans, or not test them at all?
Contra: not testing is not the best option, but we can simulate effects now, and we know what certain materials do to humans. Testing on humans could be an option, but that might be worse then testing on animals.
Pro: Then what should we do.
Ok, I'm crazy, I'm talking to myself :S
Anyhow, I'm stuck there, I think animal testing is ok to an extend, implanting a disease to then try and cure it is wrong, but testing if something that is likely to be harmless is indeed harmless seems ok to me.
Trying to get some intelligent discussions here, are you, BB? Well, good luck with that
