This essay has been acknowledged by historian Juan Carlos Usó as 'one of the best texts (...) about the rediscovery of psychedelia we're currently immersed in". Luces y sombras del renacimiento psicodélico offers a personal approach to the repopularization of psychedelics brought about by renewed scientific research and the proliferation of new spiritual and healing practices.

Thought of as an introduction for people with little or no knowledge about these 'visionary drugs,' Albert Casasayas brings the perspective of a recent initiate with a direct and passionate style that will help to demystify the usual commonplaces about these substances. At the same time, his critical focus will interest those more versed in the matter for his frank approach to the challenges and issues challenging contemporary psychedelia.
