Do you have any evidence that Effexor is actually adulterated to cause that?

I know for a fact that all of the SSRIs are incredibly *physically* addicting, by their very nature. Which doesn't mean that the drug companies did anything to make them that way. It just means that your body gets acclimated to them in such a way that stopping treatment or missing a dose can have nasty consequences.

I've heard anecdotal evidence to the effect that Effexor is particularly nasty to discontinue, but this is the first time I've ever heard it alleged that that is at all deliberate. And I've done a fair bit of my own research on psycho-pharmacology.
