RA thinks I smoke weed and he's getting tired of smelling it everyday

My RA told my friend that he’s tired of smelling weed everyday in the halls (I do not live near him enough for him to smell) the weed. I do not smoke on a regular basis and when I do (2-3 times a week), I make ABSOLUTE sure that I minimize the smell to the fullest. I have a smoke buddy, 6 cans of ozium, air freshener outside our room (my residence is a suite so that means there’s a common area within our living quarter. So the smell would basically go through two rooms until it reaches the main hallway.) Unfortunately, he thinks I am the only one in the entire floor smoking and I do not want that. He said he’s going to start taking action and I am nervous because I do not want the police knocking on my door every time my RA smells weed. Also, he told my friend that he hated me and wanted to kill me at times. EVERY guy on my floor hates our RA because he’s a douche and awkward af. Anyways I read up on the University’s policy on room searches. I found this : Personnel authorized by the University may enter assigned residence hall space for inventory, inspection, maintenance, when a threat exists to students and/or property or when reasonable belief exists that the assigned space is being used for illegal purposes. Only duly authorized law enforcement authorities, following appropriate legal procedure, are entitled to enter and search rooms and residents’ belongings. Can anyone interpret this into English please? The smell comes from this other girl who smokes near his room, but I don’t want to call her out because I don’t want her to get in trouble. Any help please I hate that I am in this situation. Currently, I do not plan on smoking for a couple weeks because of this predicament.

Don’t do drugs.
