Vaporizing for the win.

It's much better for the lungs, and conserves an amazing amount of weed.

Of course, if you can't afford one, then I would go a with bong. Cooler, filtered smoke, (THC is not water-soluble, so you're not losing it), and the ability to smoke just as much as you need, and have no excess smoke in the air (put out your bowl with a penny or something).
