Smoking near BPs?

My girlfriend and I smoke and are looking at getting a BP soon. Our main concern is that smoking is going to harm the snake. Our room is long, so long that we have a small living room setup in one half (that’s where we smoke) and we’re planning to keep the snake on the complete opposite side of the room with our bed. We already have an air purifier going whenever we smoke and the “living room” area is sectioned off with curtains that can be closed. Is it a bad idea to keep a snake in the room? Should I find another place for it?

Edit: It’s weed in case that’s pertinent information
