man i got just what you are looking for so it wont smell anything like weed at all. it works really well and it costs nothing. ok first get yourself an empty roll of paper towls or toliet paper right, then you get some duck tape and rap the outside of the empty roll with it, and all you do is get those laundry sheets that make your cloths smell good and stuff a few of them in the end of the empty roll so its like a filter. so when you inhale the smoke and your about to exhale you just blow your smoke into your homemade filter and its like magic. doesnt smell like weed at all. now you need to do something for me, please dont smoke a joint, go and buy a blunt (either a swisher or an optimo are probally your best choices) and buy some high grade weed and smoke that. this will get you split and higher then most people get, trust me i would know. after you do that you will see what im talking about.

oh and you are on your own for then smell that comes from the weed burning but hopefully this helps out some
