The usual method (at least around here) to hide up the smell of weed is a toilet paper tube stuffed with dryer sheets that the smoke is blown through. It does work to a certain extent, but I want something that works completely. I have thought about this and have realized that smoke blown through a thick and aromatic liquid, like coffee or something, has potential to work. Anyone have any thoughts on this before I try it? Maybe suggestions for a good liquid to use?

Vinager maybe

ammonia maybe
