The Smoke Buddy is a hand held charcoal filter which hides the smell of marijuana smoke. If for some reason you need to conceal the smell of weed, then the smoke buddy is what you’ve been looking for. This is basically a 2.0 version of the “muff puff”. A Muff Puff is simple to make. You just stuff the inside of a toilet paper roll full of dryer sheets. It works amazingly well. When you exhale you don’t see any smoke. There is a lingering of some smell in the air but it’s indiscernible. For the most part, the danky smell of even strong marijuana will be covered up. If you combine it with some incense or some sort of an aerosol odor neutralizer you’ll be completely golden. The Smoke Buddy takes it to a whole new level and using charcoal filters to actually clean the smoke, whereas the old “muff puffs” would just attempt to cover the smell (plus a lot naturally get’s absorbed into the fibers of the dryer sheets.) These smoke buddy things actually work!
