An anti-smoking poster on the streets of Moscow is going viral online due to its unusual star -- U.S. President Barack Obama.

Dmitry Gudkov, Russian State Duma opposition deputy, posted a picture to Facebook of the anti-smoking ad, which features Obama with a cigarette in his mouth.

"Smoking kills more people than Obama, although he kills a lot of people. Don't smoke -- don't be like Obama," the poster reads in Russian.

"I am disgusted and ashamed of what appears on the streets of the Russian capital," Gudkov said.

Obama famously quit smoking under pressure from first lady Michelle Obama, but he admitted in 2009 that he has occasionally "fallen off the wagon."

"I would say that I am 95 percent cured, but there are times where, there are times where I mess up," he said.
