Brazilian artist Fernando de la Rocque’s latest series of work title “Blow Job” was created in using an unlikely (and currently illegal) substance, marijuana.

De la Rocque’s work is set to be showcased at La Cucaracha gallery in Rio de Janeiro on Wednesday and the intrigue of seeing political and religious icons created with pot smoke is likely to draw both those interested in art as well as those who support the artist’s view of decriminalizing marijuana.

While he does not believe the drug should be illegal, De la Rocque says his work is about more than that.

“More important than freedom to smoke marijuana is the freedom to think about it and make art with it.” he said in a press release. “Polemic issues divide opinions, forcing people to think and debate. Inertia is useless when we want to overcome something.”

De la Rocque creates his art by making stencils and blowing the smoke from his mouth over the template a varying number of times depending on the darkness of the “line” designed.
