Query: Down the Junk Road And Back

This book chronicles the "life cycle" of the junkie, in which one goes from the "heroin honeymoon" period, to the ultimate devastation. It rates right up there among my favorite junkie novels, after Permanent Midnight, and Trainspotting. I'm an ex-heroin addict, and while I never was a dealer, made deals with the DEA, or suggled drugs in from the Golden Triangle, as the protagonist in this book does, Yablonsky's narrative rings very true.
