Was a real life Beerman.....
First off,
I like that smell. You should do nothing at all.
Or,
Just burn the building to the ground.
Oh wait. That might not be legal... we'll have to consult the LEO's and Lawyers here about that.
I'm just kidding ... I'm sure this is bugging you. BUT ....
Honestly, If they're not bad guys other than that, I'd just leave them alone and maybe burn some incense myself or use other air freshener. Life's too short to be a rat.
Evidently you don't work for a company or have a job that requires periodic drug screenings. Smoke a joint around me and you get to dance with new jewelery on your wrist.
My job and livelihood ranks higher up the pole than a person's right to smoke a joint and cost me my job.
That said, if you can smell it, it can enter the blood stream in residual amounts. I can point you to a guy that got rang up on a DOT drug screen because floating aromas, as some shall call it.
