Nursery stench

We’re planning on having baby sleep in our room for as long as possible. We have an extra room so we figured we’d store all her stuff in there and make it a little nursery & guest room. Anyways, my husbands brother used to live in that room and he would smoke weed in it... HEAVILY, like all day everyday, he still has his dressers in that room & it still smells a little, not like

weed but a stinky & stuffy smell.

It’s been rainy so we haven’t had the chance to open the window and let it air out for a full week without the rain water leaking in. We’re getting our carpets cleaned soon so I’m hoping that helps relive the stench, we were planning on repainting the room but changed our minds...

is there anything else that could possibly relive the “stuffy” stench in the room? Would painting the room help relive the smell? Wall plugs? Candles? ):
