[Toxique] is a simple and touching odyssey through dreams, hope, and despair; it is also a prose surrealistic poem following the inhuman time of the addict during [Sagan's] withdrawal period.

In a naïve way, Françoise Sagan turns painful memories into a moving and charming picture book; her school girl prose is the soul which animates [Bernard] Buffet's long rigid black and white drawings…. Philip Rahv once said …: "Neurosis may be the occasion, but literature is the consequence"; we could well say the same of Françoise Sagan's Toxique.
