Good point. I recalled seeing an abstract about that study, too. I easily dug it up again by entering "modafinil and rats and self" in the Medline search box. Based on the reinforcing behavior seen in rats, the authors of that 1996 study concluded that high doses of modafinil might cause addiction.
Here is what I found on Medscape's current modafinil monograph:
Abuse and Misuse Potential:
Patients should be followed closely during modafinil use for possible signs of misuse or abuse (e.g., incrementation of doses, drug-seeking behavior), especially those with a history of drug or stimulant abuse (e.g., amphetamine, cocaine, methylphenidate). Although modafinil can produce psychoactive and euphoric effects and feelings consistent with other CNS stimulants (e.g., methylphenidate), current evidence indicates that the risk of abuse or misuse of modafinil is lower than that associated with such CNS stimulants that are subject to control as schedule II drugs (e.g., amphetamine, methylphenidate). Therefore, modafinil is only subject to control as a schedule IV drug.

> I read somewhere that rats that are trained to self-administer cocaine will also self-administer Modafinil. Unfortunately, I can no longer remember where I read this, but the context in which it appeared led me to the impression that 1) the "rat" test was used to test addiction potential of a drug and that 2) if a drug "failed" the test, it was put under control. In other words, the fact that rats will self-administer Modafinil may be at least part of the reason FDA made it a controlled substance.

By the way, I am NOT suggesting that Modafinil is addicting or that it resembles cocaine in any way. I imagine there are a number of substances that rats will self-administer, given a choice.

It's hard to understand why the FDA designated Provigil a controlled substance at all. Although I'm not positive, I believe neither France nor England place Provigil in a controlled class. I think the reasons for control in the U.S. are:

I always think it's interesting that a med like Provigil, which research shows rarely causes withdrawal problems is controlled, when a non-controlled AD like Paxil causes many people to experience major withdrawal difficulties. If Provigil were imported by giant Smith Kline Beecham instead of little Cephalon, I think it's very likely it would not have ended up with a controlled designation. (Fyi, I stopped Provigil cold turkey for one week with no physical effects except a little more fatigue, and some mild loss of the therapeutic benefits of my Klonopin/Serzone/Provigil combo. Again, maybe it's the fear that some people will use Provigil as a way to purposely avoid sleeping. (By the way, it does not usually cause insomnia if taken as intended. Provigil helps me stay awake and alert when I want to be, but doesn't interfere with my sleep in the least -- even the occasional daytime nap.)
