I ran into this once.
Is your medicine cabinet on a shared wall with them ?
You might need to pull it out and put up plastic, seal it and replace the cabinet.

is possibly right on the mark. A very long time ago when we lived in Pittsburgh I think if we took our medicine cabinet out and the family next door did the same we could have shaken hands through the hole in the wall.
Humidifier moistens the air so I don't think that will help. An air filter would be better. You need a machine with a HEPA filter for the .1 to .5 micron size particles, and activated charcoal for the even smaller ultrafine ones. But most air filters have activated charcoal packs that are too small to do much good.

Tell maintenance just what you told us - your neighbors smoke, the smoke is getting into your apartment's bathroom. Could they please check the medicine cabinet and plumbing pipes for air infiltration and seal any gaps as necessary.
I doubt a humidifier would help. Try an air purifier or filter. If you rent, you can complain to the landlord and he / she should look into the issue and resolve it (sealing cracks, etc) or at the very least inform those neighbors that their smoking is entering other units and causing a nuisance.
My ex-neighbors smoked cigs and pot. My kitchen reeked of pot constantly. At that point in
time I had no idea that odors could reach my side of the duplex and I asked my nephew to smell
the bowl of fruit I had on the kitchen table to see if he smelled it. He told me it was indeed the
ventilation, not the fruit.
Would you feel comfortable asking them to please smoke outside?
I would do that before I went to the landlord.
I did call the office. They will call the apt next door. If it's still bad they will do something. I had one of my 3 litter boxes in the bathroom and moved it somewhere else. I hope the smell does not get in the kitchen!
