Most generally, in this relationship we should attend to the ingredients of set, setting, and intention. As I see it, good cannabis education and engagement with the natural world, as well as complementary therapies and practices like mindfulness and meditation are essential ingredients as well.
In the bigger social picture of cannabis use, I see the practice of formal dialogue as an essential ingredient. I would also add lots of love and imagination to this process, the ingredients of compassion and creativity if you will. Vision, both personal and collective, is an essential ingredient as well.
Thus in the human-cannabis relationship, we combine the great gifts of cannabis with these great gifts inherent in the human condition, if only we nourish them.
