This is so far reaching @yoorgue. I can literally tell you 100 health issues that can be helped by the cannabinoids that are commonly found in this plant species. That part is almost mind boggling. In my humble and personal opinion, everyone should be freely allowed to grow their own cannabis and every household should have at least a small supply of it in their medicine chests. You'd need 30 grams or 1 ounce of dried plant material to make an infusion. Once made, this can last a single person about 3 months.
