Re: Shisha smoke indoors
What about getting a nice HEPA air filter? Combined with a closed room with maybe a cracked window, and I'd think that's about as 'safe' as you could get.
I've got a 'decent' HEPA filter and I smoke inside, both cigarettes and hookah, and most people can barely notice the smoke smell.
Sorry bout bumping such an old thread, I was just rather surprised that no one mentioned air filters.
