This unique (and definitely illegal) technique is used by Brazilian
artist Fernando de la Rocque and involves smoking lots of pot before repeatedly
blowing the smoke at a piece of paper with a stencil taped to it.
According to Yahoo! News!, the 32-year-old says he stumbled on his toking technique in 2009. Each of Rocque's pot-stained prints take about a week (and about five joints of smoke) to complete. But before you mock this artistic pothead, take note that the stained portraits are selling for around $2,500 each.
