drugs?

[shinedsprite.livejournal.com]

 hey, sorry to keep asking, but, are there any fics around which focuses on drugs? Specifically past usage by Jim? His teenage years are often painted to be pretty, ahem, lively, so there must have been drugs involved?

I was kinda thinking of stories where the crew find out? Maybe about a past addiction or withdrawal or just a rumour going around the ship?
I;m not fussy on any of the other particulars, I just want a it of Jim's past to come out. 

Thanks in advance!
