I know about the original Sherlock and his addiction, it’s also referenced in the article. (Though I doubt it was crack, but the powdered form of cocaine common at the time.) I don’t think we can always assume anything about present Sherlock, though, because I don’t think he is intended to be his namesake. Yet, the indications that he was addicted are pretty obvious once you put them together.
This is the view from the spot on the wall where Sherlock fell.

No bins that I can see. The two buses did, of course, block John’s view and he never saw Sherlock hit the ground. Then that guy on the bike ran into Watson as he ran across the street, so he was delayed getting to the scene. Both buses pull away as he arrives revealing a group of people already around the body.
Actually, he couldn’t. The guy on the left in the picture below was wearing a stethoscope (not visible here) and is taking Sherlock’s carotid pulse in the only part of his neck exposed. This prevents Watson from doing the same. If you watch the scene, there are people surrounding the body keeping Watson away and he reaches for the only hand he can reach, the right hand, as, in previous view, we see his left arm is at his side and out of Watson’s reach. After he feels for the pulse, they immediately pull him away and the stretcher comes and takes away the body.

Molly Hooper. I’m not convinced about the ball, either and I did wonder about a drug, but I was wondering if he literally got something to stop his heart and trusted her to revive him quickly before brain damage set in. It would explain the amount of anxiety he displayed when Moriarty killed himself.
I wish I had some comprehensive theory that accounted for all we see, but I don’t. Moriarty gave us a clue, I think, and that was that Sherlock always wants everything to be complicated. I also think the writer threw a few red herrings our way, like that ball, perhaps.
One of my ideas is that the people surrounding the body, for the most part, came out of the bus and are all Mycroft’s people.
