it COULD work, but it's the biggest waste known to man,
You'll get like 25% of what you burn that way, may as well just light it and suck the smoke in.
Trust me mate, that is POINTLESS.
to roll a joint, you need rizla papers, tobacco (unless you make a complete weed based joint which is kinda dumb), your weed, and if you want, some cardboard/part of the rizla pack to make a roach so as the tobacco/weed doesn't go into your mouth when puffing (basically a filter).
If you have all that, then attempt to roll a few with tobacco, chances are if you do it with weed, you'll drop half of it.
There are many different way's of rolling, for this example, I'm just going to presume you are using normal rizla's.
The rizla will have a crease in it, pop some stuff in there, then with your left hand, take the left side, and with your right hand, take the right side.
Make sure that the gum *sticky bit* is at the top.
Then slowly and gently squeeze and roll up with your thumbs so the tobacco is covered by the paper completely, then with your forefingers, push the rizla over your thumbs and push it down and remove your thumb.
so then,your kinda holding the whole thing, using your forefinger and your middle finger of each hand, then with your thumb at the bottom roll upwards, this will make it tighter otherwise the whole thing is pointless. then lick the gum, and roll it up completely.
This is a terrible explanation, plus there are easier ways, but they would take ages to explain, plus you have to learn to do it unaided.
Don't put your weed in for the first few attempts, chances are you'll drop some.
Now, I just want to say, I think it's a BADDD IDEA to do this, alone, specially at 14.
But if you want to do it, who am I to stop you.
