For some people, the plumes of smoke rolling off a joint are a nuisance. But for Brazillian artist Fernando de la Rocque, marijuana smoke is a creative medium. Using handmade stencils of cultural, political and religious figures, de la Rocque "paints" with cannabis smoke by blowing puffs onto a special type of paper that absorbs tokes.

Joints are his preferred "paintbrush" for crafting cannabis portraits, which usually take a week of smoking five joints per day to finish.

"You could say I'm taking advantage of an 'ink' that's just being tossed into the air," de la Rocque told the alt news website Newsivity, who also filmed him at work. Check out this clip of de la Rocque honing his craft. Maybe you'll get inspired to dip a paintbrush into your bong and experiment with watercoloring.
