Now that the law Fini-Giovanardi has been erased by the Constitutional Court - after 8 years of application with millennia of jail for the sum of sentences, so many broken lives and some dead in prison - also in Italy the prohibition on cannabis has the days counted.A success of the variegated Italian movement that supports global changes, from Uruguay to the United States, thanks also to the strong social drive triggered by social media and digital.The historical decision of constitutional judges reiterates the urgency of pragmatic and modern policies at the pace with the times, confirming the centrality of a plant used always and everywhere at the therapeutic, food, industrial, religious, as well as social and recreational level.An accurate and up-to-date excursus to illustrate the thousand qualities and potential of this common good - beyond the widespread and increasingly less forbidden use of "stupefacente".
