The Spanish Observatory of Medicinal Cannabis (OECM) was born in October 2015 with the need to promote, coordinate and carry out activities and projects aimed at understanding the properties and medicinal uses of cannabis and its derivatives. Likewise, it intends to advise public and private entities and inform institutions, the media and civil society about the current knowledge about the properties and medicinal uses of cannabis and its derivatives, based on the results of scientific studies and clinical trials.
