I do not think this is true at all. I've been addicted to drugs before (cigarettes) and I certainly was not happy with that. And I've flirted with alcohol addiction too. Again, that was hardly a positive situation I was comfortable with continuing. I've known others, too, addicted to stronger things. A friend of mine battled a speed addiction for a year. He could very much imagine getting by without it - in fact he quite desperately wanted to, he just couldn't. I would presume the same is true for many, if not most, addicts of heroin. Anyway, my understanding is that modafinil is not a drug of physiological addiction. It's a tool that one uses to overcome certain physical limitations, if and only if that is required. Think of it as a headache pill, but for tiredness. Certainly that is how I and everyone else I know who uses it views it.
