Vaporizers: The easiest way to use marijuana

With a vaporizor, you only inhale the THC (the drug which makes you feel good), not the smoke or burning from the plant.  Vaporizers also produce significantly (nearly zero) smoke, so you can use it in your house or apartment without it smelling like marijuana. Finally, vaporizers are more efficient than a bong, as the plant isn't burning while you're not using it.
