Best way to get ventilation into bedroom

[DangerousD]

Hi all,

Not sure if this should really be a window/door category Q but anyway: I'm wondering what my options might be to get clean air into my bedroom, given that the area below it is used for smoking. Unfortunately the smokers refuse to move away, and I can't really open my windows without getting smoke in. Is it possible to ventilate via the loft somehow, or via the (no longer used) chimney, or some other way?

Thanks in advance.

Bit of a curious situation this one, but if you were to install something like a bathroom extractor into an outside wall, would this allow cleaner air in from under your door or something?

Probably ring someone like Passivent.

Probably pi55 out of the window until the anti-social bsggers get the message.
