The world's cleanest car is made of cannabis!

The car didn't attract much attention in Denver, a city even though marijuana is legal there. There was no crowd around her. Passersby didn't stop to look at her.

Maybe it's because it just looks like a Mazda convertible—except for the portrait of George Washington smoking a joint on one of its doors.

The chassis of this one-of-a-kind prototype was taken from a Mazda Miata. But its body is made of hemp, whose fibers were woven, placed in a mold, hardened with resin, and coated with paint.

Its creators call it the greenest car in the world, despite its bright red color.

The body is made entirely from agricultural products. The engine can run on biobutanol, a fuel made from agricultural waste which gives off the smell of trash, wood shavings, and alcohol.

Designer Bruce Diezen hopes to bring the industrial hemp in the floor and other parts of the chassis, in order to put this cannabis-based car next year at a price of 42,000$ (approximately 37,000€).

«One version blows your mind. The other can make a car. ». But they're both cannabis," he said. And just so you know, he doesn't smoke cannabis.

Diezen, who is 60, moved to Key West after a career at Hewlett-Packard. He says he was inspired by Henry Ford, who himself built a hemp car in 1941.

Dietzen drove his car from Florida to Denver, where he hoped to attract investors to finance his cannabis car. And just in case anyone had any doubts about his car's impact resistance, Dietzen hit the hood a good dozen times. Not a single dent.
