I may have overreached a bit in my comment above. I agree with you about the presentation of narrative facts in the past of the series, but hold my final opinion in reserve as Moffat and Gatiss work drama first and then come up with ways to knit the story back together in a way that appeals to the viewer to suspend their disbelief. I.e. if they think it's more interesting that Sherlock has been stoned the whole time, then they will probably work that in.
