Make a gravity bong. Whenever i'm low or just feel like getting really high really quick, I always use my gravity bong.
Pretty easy to do, you need a big container (for water), a smaller container (a milk jug or a big water bottle will do, cut off the bottom), and something to light the weed on. Put the small container in the big one, put the weed on top of the small container, light the weed and pull up, making the pressure push the smoke into the bottle. Then remove the top, wrap your lips around the small container, and breathe in while pushing it into the water. It will force a lot of concentrated smoke deep into your lungs, and get you wayyyy higher. :thumbsup:
