Yes you need to crush up the weed really good into a packable consistency..
I have a perfect size steel rod thats fits right through for cleaning. After a week of smoking thru it it, if you push the rod thru you get some nice resin..
nice resin. Great system the dugout. You can throw that resin into the stash side. Good shit. Use it all the time. In reference to getting real close to people with it I dont recommend this as alot of people just dont understand weed at all. Cops are good at spotting these type of things too. Plus you have to keep lighting the thing to get the 2 or 3 good hits....
