Breaking down your weed by hand can be a very time consuming process, unless you only have a small amount of weed. A grinder is the best solution to breaking down weed. A grinder will make a very consistent mix of weed thats perfect for joint rolling or bowl packing. You can get a grinder for as little as 3 bucks or you can get a really nice one for as much as $100 or more. Our personal recommendation for beginners is to start small. We suggest this one because it is very cheap ($1-$5) but it gets the job done.
