I find this topic interesting.

Ok, lets throw away the moral implications for this argument, just for the sake of argument.

Here are several reason why testing on pedophiles isn't a good thing

1) Pedophiles tend to have mental illness, which could effect the outcome of the drugs.

2) Although there "seems" to be a lot of pedophiles in America, there aren't nearly enough to get rid of the need for animals in testing.

3) We specifically breed most of the animals used in testing in order to make sure they are "blank slates." We can not do the same with pedophiles.

4) Prior drug use (even legal drugs) can alter the effects of the designed drug.

5) There are far to many variable dealing with humans to show the actual effects of the drugs.
