"The study of the multiple expressions of marginality in the Balearic Islands is a little-explored field from a historical perspective," says historian Tomeu Canyelles (Pòrtol, 1984) at the beginning of his latest book, where he confirms his intention to reverse this trend. Riding the Abyss: Drug Culture in the Balearic Islands (Leonard Muntaner) traces the recent—and not so recent—history of the Archipelago through the impact of substances like cocaine, ecstasy, and heroin on the economic, social, and cultural spheres.
