He was intimate with this girl in the past, and she used to live here. She was doing heroin. She started doing it a lot, heading toward junkie status, so he kicked her out. He's beating himself up because he drove her somewhere to get some for her birthday, 3 months ago. From what he's told me, she wasn't doing it a lot then. I guess she really spiraled in the last few months.      

I officially moved in yesterday. I haven't known him that long. This sort of situation is very new to me. I have only known a few junkies (never friends, only acquaintances) and have never had a friend/lover/ex-lover die. He and I get along but we're not actually friends, yet I feel I have an obligation to comfort him through this, being his roommate and all. And I do feel bad for him. I'm sure losing someone you were intimate with is very hard. How do I approach and handle this situation?     

For clarification purposes, I'm 99% positive he doesn't do any hard drugs. He seems to be strictly pot and alcohol. He actually just threw a roommate out because the guy started smoking crack. We live in a fairly urban part of the city, where these drugs are a bit more common. My roommate has a good head on his shoulders and knows not to mess around with people who do that stuff.

Roommate's friend/ex-lover is dead of an overdose. I've never had this happen to me or anyone
