I can understand the concern because of the odor, but your question did not include smoking marijuana or taking marijuana pills for medicinal purposes. 

As soon as I and renewed the lease the tenant wrote me this long message with all these things wronge, including drain smells bad(she’s been putting bleach down the drain to kill the odor, the lights in the kitchen and bedroom are flickering(this ones easily fixable) & the bathroom floor is in-caving because of water damage(she suggested a new shower door).

Was the odor seeping through shared vents or through firewall or what?

We have steam cleaned the carpet several times, but the odor remains.

[ Nitty - Gritty Rental Management Stuff 101 ] Smoke odor in an apartment - would appreciate opinions, recommendations, some magic spray or powder you've used, any ideas to eliminate the odor.

some have told me that I should pour a cup of bleach into two gallons of water and wash the whole place with this mixturesomeone else mentioned a bowl of vinegar placed in the middle of the floor.I have also tried Coffee which did help absorb a lot of the odor but there is still a lingering scent.I am frustrated because I am no expert cleaner. and I cant believe that washing the walls and doors did not solve this issue.
