the way to get highest with the smallest amount of weed is a gravity bong but im assumeing your new to weed so you might not be able to even take a gravity bong hit...but if you want to try it there are plenty of threads on how to make them...the reason bongs fuck you up so much more is because it cools the smoke so its easyer on your lungs and you can take a much bigger hit because your not burning your throat. and when you clear the chamber your inhaling alot of smoke in a short time
