I've recently started writing about marijuana (recent meaning the last year or so). I started smoking it, so I started writing it into a lot more of my stories, especially since my characters (Panic and FBR fandom) smoke.
Snow and Ice was never finished but it had to do with distribution of cocaine and crystal meth and drug turf wars. Ryan does cocaine.
Conversations on a Thursday Afternoon is pretty much about Brendon and Ryan talking and smoking.
Confusion is the Strongest Emotion is really long so it's not the most strongly focused on thing, but Brendon smokes weed and Ryan really dislikes it, so it causes some friction.
Supermodels Don't Wear Underwear has a "circle" scene with Ryan's first time smoking.
& We Die of Broken Things Like Hearts vaguely deals with cocaine addiction/withdrawal. It's not the focus and the withdrawal symptoms are never stated as such. I included irritability, fatigue, hunger, and paranoia.
A Year and an Ocean of Distance is probably my first "smoking" fic where I actually went into details about it.
The End of Days is about a boy who is raped about being drugged, so I guess it would technically count. He has to deal with feeling heavy and blurriness and things like that having to do with drug (and also being raped, of course).
Down the Rabbit Hole involves marijuana as well as powdering pain killers to snort them.
Manic deals with side effects from properly taken prescription drugs.
Stories of mine with marijuana use that isn't really focused on:
Something Like It,
The Boy with the Protest Sign,
Can I Keep You In My Sights?,
9 Months is a Long Time,
Coming Up the Stairs to Our Room,
Go Ask Alice.
Stories of mine with mentions of other drug use that isn't the extreme focus:
Little Boy Lost (heroine),
The Complex Kids (cocaine and marijuana).
I also have countless stories dealing with cigarettes and alcohol, but I don't think that's what we're getting at with this thread.

It's easiest for me to write marijuana usage because I do it so I can relate back to that. For the story with cocaine withdrawal I did some research, but since it was the intense focus, I didn't do extreme research. For
Snow & Ice I did no research except watching a few movies, which was probably a mistake.
One thing I hate seeing is someone ash a joint like they would a cigarette. You don't do it in the same way. I don't even ash joints. I just blow the ash off.

I remembered a mistake I used to do was that I thought a joint and a blunt were the same thing and I used the terms interchangeably.
