I've been hearing a lot about the smoke buddy, so I decided I wanted one. I went to my towns only head shop, and they didnt have them. So I went down to home depot and got stuff to make my own. I'm sharing the instructions so that other people may benefit from this fine device. Materials needed: 3m Respirator Mask(or other brand, this uses a 3m) Hot Glue Gun Hot glue sticks (or other sealant) Basically all you have to do is reverse the respirator. To do so, first take off the white screen things that restrict outward airflow through the filters so you have something like this: Second seal up the regular air intake in the middle with hot glue or some other sealant. it will look like this: Thats it! Exhale your hits through it and they will disappear. You can even stuff dryer sheets in the filter spot along with the filters Happy toking peeps!
