I was recently placed on probation for driving under the influence and am trying to comply in every way with the terms of probation. I live in a home with a roomate who also happens to be the homeowner/landlord. My problem is this: there is quite a bit of drug use in the house by the landlord and his guests. I know I'm not supposed to be around that stuff and informed the landlord I needed to move out as soon as possible. I explained that I could get in trouble if there are drugs being used in my residence or I am around people using drugs and I can't rely on his behavior (regarding drug use) to determine whether I stay in good standing with the law for the term of my probation. He, though, is intent on not letting me leave the lease early (which runs through summer). I told him I'd try to find somebody to sublease the place to, but he isn't warm to that idea, saying that "he would want somebody to move in that he knows/is friends with, because he wants to be able to use drugs in the open without worry".
To the point: I'm leaving, I know I cannot be around such behavior and I'm moving in with my girlfriend. The landlord/roomate I have now is kind of crazy and independently wealthy, with no job and nothing but time on his hands - so I'm sure he'll pursue this in court. If he decides to, I plan on telling him that if he takes me to court, I'll be forced to explain exactly why I broke the lease, in explicit detail, and maybe that will stoke his paranoia and he'll lay off - but I'm wondering if I have any legal right to break this lease because of what's going on? I don't think I have any video or photographic evidence of drug use in this house, but have plenty of friends who have been around when cocaine and marijuana have been used out in the open. I don't want to be a rat, but this is my butt on the line - I can't be around these people or this behavior anymore. Will this lease be enforced if it goes to court? Thanks for your help.
