Hi. I has never used marijuana before so please forgive the idiotic questions. He has got some resin and has bought a pipe but does not know how to use it. The pipe is like a tube with a screw on piece on the end with a hole in it. Should he put some tobacco with it or use it on its own, and how do you light it ? Do you light it and then put it in the end then screw it on or just put it in the end, screw it on and hold the lighter underneath the end. I am confused !
