Smoking is definitively unhealthy, never smoked, never will. But other forms of intake like essential oils, tinctures, etc. may actually be pretty healthy as mentions this documentary. "Cannabis cancer research studies". Food agencies like FAO consider the hemp plant a superfood for its high content in nutrients with the plus that it is completely legal to consume the hemp part of the plant.
But there's no need to go exotic to be well nourished, there are many healthy foods to eat that we seldomly use in our meals. I've used hemp flour for breads and recipes but I found it exotic and expensive to acquire so I resort to healthy and easier to acquire foods. I can't say I consume weed in any form but if it gets legal and affordable why not?
