For packing a bowl just break it up and remove stems and seeds and break it into little ball sized nugs. When you pack the weed into the bowl don't pack it tight! If you do that then it will burn really shitty and will get stuck up in your pipe making more hassle for you to deal with. Just pack it lightly and soon enough you will get the hang of it. For joints, grind it up good and roll it, if you can. Rolling joints are very hard..
