I cannot speak to the probabilities of others but I can give you an anecdote: me. I am dosing modafinil without a prescription (the deeper irony here is that I would actually qualify for one "on-label"). I studied the literature and 'folk lore' on the issue before making my decision.
If I am at all representative of a reasonable approximation of a rational 'typical' modern person, then I'd say that the probability is very high. (Then again, looking at how my comment history on LW has been treated that may not be a safe assumption.)
Piracetam, on the other hand, appears to have no discernable effect. I'm not even sure that placebo effect occurs; self-reported "diagnosis" of memory is a poor guide for comparing cognitive abilities -- and no material test to my knowledge has demonstrated improved cognition as a result of dosing any of the 'racetams.
As to the "etc" -- case by case basis, really. I know apocryphally ("truth in journalism") there are many college students and postdocs who 'abuse' adderal.

Not sure that is really equivalent; adderall is an amphetamine.
Often, there are questions you want to know the answers to. You want other people's opinions, because knowing the answer isn't worth the time you'd have to spend to find it, or you're unsure whether your answer is right.
LW seems like a good place to ask these questions because the people here are pretty rational. So, in this thread: You post a top-level comment with some question. Other people reply to your comment with their answers. You upvote answers that you agree with and questions whose answers you'd like to know.
A few (mostly obvious) guidelines:
For questions:
For answers:
This thread is primarily for getting the hivemind's opinions on things, not for debating probabilities of propositions. Debating is also okay, though, especially since it will help question-posters to make up their minds.
Don't be too squeamish about breaking the question-answer format.
This is a followup to my comment in the open thread.
