The lightbulb vaporizer is a cheap easy wayto do it, and it wastes almost zero weed. This was my first smoking device, before I decided to buy a bong and start baking it.

MAKE SURE TO CLEAN IT OUT REALLY WELL! I cannot stress that enough, you don't want to be sucking in fumes from other shit that could be seriosuly harmful. The white paint on the inside of a bulb can be removed with salt (just shake it around inside) Then use water and more salt to get the rest, and then give it a good rinse. I wouls also recommend some isopropyl alcohol instead of water to shake around in their to give it a really really good clean.
