If you want the ultimate in pain/sleep meds... Duurty Dragons. It's the first auto I've grown that I can only smoke once or twice a day, MAX (40+yrs smoker). I've grown and smoked some Magic Dragon, and it is good but the Duurty knocks me into the duurt. They're really, really pretty too... not that it matters.
Some of the other Dragons may be as good (don't see how they could be better) but I haven't grown them yet.
