Doob tube, sploof, personal air filter, or whatever else you want to call it, this is what stealth smokers need. Worried about the smell getting out there and someone finding out about a smoke sesh? This is the answer. It’s perfect to discreetly smoke at home, the office, in the car, the hotel room, or when traveling.
Take a hit from a pipe like normal and blow the smoke through the tube/filter. The smoke that comes out the other side will smell like drier sheets. This isn’t really recommended for when you’re smoking a joint though as there’s just too much smoke coming from the j itself.
