My stupid neighbors smoke !

Abigail • in love with my bestfriend. due date on june 4th. love my family and God.
Im 18 turning 19 ending of may.... I've been at my mom's due to no vehicle and I'm almost due ... June 4th ❤❤ . I have my own apartment, my neighbors smoke. The bottom, across, and behind me all my neighbors smoke. It goes through the walls ... Especially and mostly in my closet ! What do I do? What can I do to protect my baby and I from second hand smoke?? I have no money to move again? I complained many times... Is there anything I can use or do? Air cleaners?? Help ladies please....
