History of the Bong

[Cleveland]

I just found something that says an African tribe, the Bong'om tribe..invented the bong specifically to smoke cannabis. But I'm more talking about popularity, I guess.

This is still cool to read though, here's a link for anyone interested.
On Marijuana | The real history of the bong

Its an ok article. almost every sentance or statement contains the word 'assume' though. and it's not at all factual.
