Brian is addicted to drugs

[deviant-queen.livejournal.com]

I'm looking for fics in which Brian has a serious drug problem. I've read one or two about someone in the gang realizing that the drug use we see in the show is an issue and trying to convince Brian he has a problem. I'm talking about a legitimate, serious drug addiction. I'm not really looking for rehab fics or fics referring to past drug use either, unless there are scenes in which Brian uses.

I vaguely recall a fic where Justin was the older one (I think) and Brian had a drug habit he used to numb the pain and rejection he received from his screwed up family. Justin develops feelings for him and tries to help him. This could just be an idea in my own head and, if so, I might just have to write it.

I'm open to stories in which Brian and Justin are both addicts that enable each other's addiction, if any exist.

A couple related fics found in comments.
