Well, assuming you don't have a cardboard filter, the answer to the question "which end do i light" is THE ONE THAT'S NOT IN YOUR LIPS!
If you can smoke a cigarrette then you should be able to smoke a joint... same basic principal, except you have to double inhale to get all the smoke, and you have to blow out the flame when you light it up, or you'll end up torching all the weed.
