Probably the one of the oldest forms of consumption, is a good old pipe. Ground-up Cannabis is placed inside of it, and heated up. The user then inhales. Pipes are typically made of glass or ceramics, but can be made with other heat-resistant materials.
It should be noted that archaeologists have uncovered 2,400-year-old golden bongs used by royalty to smoke cannabis and opium in Russia. The bongs were uncovered in a secret chamber covered with clay by construction workers during excavations to install power lines. The ancient paraphernalia was found alongside 7 lbs of other gold items—three gold cups, a heavy gold finger ring, two neck rings, and a gold bracelet.
Experts believe the bongs to be the oldest in existence—used by Scythians, an ancient Iranian nomadic people who dominated the Eurasian grasslands for almost 1,000 years, roughly 800 BC to 300 AD.
