Input: Living together for 5 months, friends for over a year. Separate rooms. 
I bought pot a week ago and self medicate. (Please, let’s not drug shame. It’s legal, this isn’t my first time, I know how to handle it, yes it’s necessary.) The first day I had my small piece out in the kitchen. Roommate comes home, sees the weed (he knows I smoke), we talk for a bit, joke around, everything’s fine. He goes into his room. Comes out 10 minutes later completely different person, with a deadpan look. He says “NO smoking in the apartment... You can smoke in your room, but not out here.”
I was so caught off guard by how authoritative and aggressive it was, it took me a moment to respond properly. Like a “hey man could you do that in your own room” would’ve worked. But of course I was super embarrassed and apologized and reassured him that he had every right to ask that of me. 
So now I smoke in my room, but I guess you can still smell a little in the hallway. I never noticed anything, but roommate has completely iced me out so I can assume the smell is there. Not only that, but his entire attitude towards me has changed even when I’m sober. He’s always been judgmental and hypercritical of me, but now it feels even more so. When he’s angry it is frightening. He shows it, like slamming doors, death stares, those sharp exhales through the nose every time he walks by you, etc. I’ve tried to make normal conversation with him these days. He either just stares back and then ignores me completely, or sometimes responds condescendingly. Tonight he came home right after his gf confirmed how pissed he still was because of the smell, even though we all obviously knew. I started to say “hey, sorry I opened some windows and bought some room spray” but he just angrily said “yup” without looking at me, stormed into his room, and slammed the door. 
It’s felt like walking on eggshells around him since day 1 of living together (even before weed was in the picture) and I’m honestly sick of the treatment. I’m sure he’s unaware that he does this (because he has a good heart) but he’s just always in a bad mood and has to suck everyone into it too. The second he walks into the room, the vibe changes. There’s so much tension and anger with him, I’m literally scared to be in my own home these days. It’s like a psychic attack every time I see him. 
Seems like the only solution is to not smoke in the apartment at all? Which I would’ve happily agreed to, if he had just asked me himself instead of hiding behind angry attacks all week. His behavior and attitude are so disgusting I don’t really feel like changing my lifestyle for him either.. but I do believe in being respectful of shared space at the same time? He has a big reputation for being the stereotypical “angry negative French man” so he obviously needs to learn how to manage his emotions and communicate like a grown ass adult. 

Mixed reasoning. Genuinely wondering AITA?
