Thanks Valen, I contacted my landlord today and she was very understanding about it and said she would take care of it. I told her that I'm spending thousands of dollars and dedicating years of my life to my schooling and if I get caught with pot in my system (though highly unlikely with second hand smoke) that it would ruin my academic career and my future! She took that pretty seriously and told me I should certainly not have to put up with it. I try not to judge people, I mean its not something I choose to do... But when it's affecting me and my health and my future, I can't just let sit around and let it happen. Now I just wait for the explosion from my neighbors... Nervous about them confronting me! But I did talk to them first and give them a fair warning!
