I (21m) recently moved in with my roommate (22m) a couple months ago. We aren’t very close however things have been mostly smooth and we haven’t had many problems. I understand he has side hustles however I believe this one has crossed the line. 2 days ago he had 400 nitrous oxide tanks delivered to the apartment, and they have been sitting in a messy pile taking up the entire living room and entrance way ever since. I have asked him multiple times to move them. He keeps on telling he’ll do it later but it’s been two days and honestly idk what to do. Any advice? I’m worried he might have a substance abuse issue so I’m afraid to be too assertive.
