I have no clue where the money goes. I know that the BS supplies that we used to get all the time, pens, notepads, desk toys, etc - those are more or less gone - not allowed apparently anymore.
Of course spending who knows how much on lunches/dinners, etc still happens - the claim is that that is the only way a doctor will stop long enough to talk to a drug rep about a new drug. who knows if that's true or not.
And talking about universities - man those places are perhaps the most corrupt of all!
