With fair reason we could say that the difference between non-cancer pain and oncologic pain is found in the doctor who treats them. This is based on the premise that an EVA 10 score exists for both. However, one of the problems when it comes to treating it is the expected survival time of our patient. We say, then, when we think that the patient has a life expectancy of less than three months, as in the patients of the Palliative Care Service, we do not tremble to prescribe an opioid. On the contrary, when we are going to use opioids for long periods, we immediately weigh the side effects to which we are going to see avocados. Be that as it may, opioids –as they are–, one of the fundamental pillars in our struggle against pain, we must be cautious with its use. Literature invites us to look at our patients suffering from pain from different points of view and for that, to put at their disposal a multidisciplinary team. Likewise, it refers to multimodal analgesia. He asks us to spare no effort and not to take for granted or against or in favor. It indicates to us that each patient is different, that the norm does not exist and that we must look for the intermediate point between the dose and the poison. Limit that otherwise is not always in the dose. Within this context a new ally, new in our eyes, we find cannabinoids. This article aims, based on the evidence gathered –along with some suggested doses–, to share the way of thinking of the authors about its use as part of the analgesic arsenal of algology.
