Overall I've liked Elementary's tackle on Sherlock's addiction/recovery overall. BBC's Sherlock hasn't really spotlit this other than a little in "A Scandal in Bohemia" and I haven't seen it enough times to make a comment on it.

I think Gatiss and Moffat said they felt it was an overused trope in Holmes adaptations, and that the cocaine use wasn't all that prevalent in the stories, more of a passing reference than an aspect of the character. I don't think I need to see a story about it to be honest. I'm content to have it as something in the past, and that he's sort of transferred the addictive personality to solving crimes.

*GASP!*

I know!
