I've got 2 girls in a cab with a DIY scrubber (kitty litter, you can use that instead of activated carbon) in an apartment right by the elevator on my floor. I have friends who smoke over who don't know it's in my bedroom, right beside the bathroom, and they have no idea that I'm growing even though they walk right by the room (the door is closed).

Make or buy a filter and do it in your apartment. Jack's right about it being much safer. Plus then you don't have to go anywhere to take care of them girls!
