At home I always smoke my home-made bong in the bathroom with incense burning, a small electric HEATER on, and the window open, and playing music. The weed smell mixes with incense and the warm air inside gets sucked out the window. I also have a radio on, or play a tape or CD to cover up the sound of bong rips.

I have an empty film canister that I cap the bowl after EVERY toke to snuff it out, and I continue to toke after I cap the bowl until all the smoke is sucked out of the bottle. I light the bowl for every toke.

My home-made bong is made from a vitamin bottle with the rubber stopper and stem from an old water pipe, aluminum foil with holes punched in it taped to the bowl, and about 2 feet of 1/4" vinyl tubing. After smoking I disassemble my bong and hide each part in a different place.

Don't carry weed or pipes in your car unless you have to.
