In his heart of hearts, L probably understands that he is the type to make people want to drink more, if only to make his presence slightly more tolerable. And that's admittedly difficult, even after years of having essentially the same difficult personality. He can be endearing once a person has gotten past the initial abrasiveness... but the curiosity never goes away or lessens until it's been sated. This curiosity had been a boon during school, and had plunged him into a world of trouble the first time he'd been offered cocaine; it was a mixed-bag regarding his detective work, because on occasion, he is set up to pry into things that are bigger than he is and that can swallow him whole.
