Cornering

If you're offered the "green hit" (first hit), take it, but don't light the entire bowl. You can take a nice hit and still leave most of the green intact. This is called "cornering the bowl." Hold the lighter at the end of the bowl and suck the flame towards one corner of the weed. If the bowl is packed, there should be enough green for three or four people. (This tip is most appreciated with smoking expensive marijuana.)
