Easy way to find out buy something cheap and ship it to your neighbor. Your neighbor will have a bad day but won't won't get in trouble and there won't be any evidence that he bought it only that someone shipped it to him/her.
This may result in your neighbor being raided and possibly being injured (and small chance they might be killed). Please read the description of some of these botched raids http://www.cato.org/raidmap before you willfully endanger people you should be looking out for.
If you get drugs shipped to your house, they will charge and probably convict you. Doesn't mean it would hold up in an appeal, but why would you risk an innocent's life, freedom, finances, and social standing just to order drugs off the internet?

All I was responding to is your statement, "One of the most irresponsible things I've ever read." If I ranked all statements I've ever read in order of irresponsibility, this is pretty middling.
If you don't see the irresponsibility of implicating an unknowing third-party in a serious life ruining felony, I don't know what to tell you.
Given that this is most likely filled with vendors who are either agents or guys who have been popped and are now confidential informants, your statistics are way off.
But that is just low. What kind of psychopath do you have to be to ruin some innocent persons's life just because you want to check some theory.
