For some reason, I was recently reminded of something I had seen in a High Times magazine over a year ago, but I can't remember the name of it. It is a device to use to avoid spreading the smell of by blowing the smoke into it. Does anybody know what this is? If you do know what it is, has anybody ever used it before? Does it work well? Thanks.

A ghetto version is a "Doob Tube" where you take an empty roll of toilet paper and put lots of dryer paper in there. Works alright.

i saw that. it looks like a chapstick tube. it contains a carbon filter i think.
