First up you need a pack of SKINS. Their are loads of skins on the market and the most popular ones would be Rizla, Swan, Job etc.
Load your skins with tobacco then start burning or picking your weed into it. The art of resin crumbling is also an acquired skill. Ideally you want all the weed to be powder right along the joint.
There are many techniques to the rolling of a joint and the chances are that your technique will be personalized. You can put your fingers horizontal at the top of the filled area of skins and roll it over with your thumbs. You can create a fold right along the joint then roll it over along the fold. Rolling takes allot of time to master.
Once you have rolled, poke down the sparking end then twist it. Then make a roach by rolling up cardboard (you need good roach, not just any cardboard) and put it in the other end.
Then spark up your joint and SMOKE IT!
There are loads of names for a joint. Here are a few...
reefer, jay, jaygo, spliff, bifter, jeffer etc etc
