Prolly the gravity bong. Just pack it up with one hit worth each time, and burn all of that. The GB allows for the most efficient uptake b/c along with natural inhalation, it forces more smoke down your lungs and up into the alveoli(absorption balloons at the end of bronchi)
coledog855 Reviewed by coledog855 on . Most efficient way to smoke? I've been trying to figure out what type of pipe/device smoke's the most Efficienty. I think it depends on a number of things, bud hummidity,bowl size and how long the goods are allowed to continue smoldering after a hit. Like when I smoke thru a pipe I always cap off all air to the bowl with a thumb as soon as I'm done takin a hit. I like my Proto pipe for this exact reason. It has a lid on one end and a small mouth piece one the other end, makes for a thumb freindly setup:thumbsup: What's Rating: 5
