Wagner Moura, the star of hit Netflix series Narcos, has called for drugs to be legalised.
The Brazilian actor said he had learnt a lot from playing notorious Colombian drugs kingpin Pablo Escobar, who became a billionaire through the production and distribution of cocaine, in the show.
Wagner told the Press Association: "The drug trade - the Narcos craze - is a very, very big deal. It's a big problem for all of us, especially for Latin people. I think it's very important.
"I have learnt so much about it by doing Narcos and it was so important for me politically. For example, I always thought that drugs should be legalised."
The 40-year-old added: "I see the policy towards drugs, especially in America, North America and South America, is completely wrong. It's proved to be a flop.
"I think that addiction is a very, very important thing that has to be treated, but has to be treated as a health problem and not as a police problem.
"The amount of people who are dying in the war, especially people in poor countries, countries that produce and export drugs like Colombia, Peru, Bolivia, Brazil - I would say that is much more than people who are dying of overdoses. There is something fundamentally wrong with that policy."
Pablo himself died in 1993 at the age of 44, which means Moura will be making his exit in season two.
Having read "everything that was written about Pablo and modern Colombian history", moved to Colombia with his family for two years, learnt Spanish and put on 40lbs to play the role, it will be an intense experience for Wagner to leave behind.
He said: "During this time I was dealing with a lot of bad energy of course, he was a very mean person.
"But at the same time he was a human being. He was a dad, you know. He was a family man, he was someone who at some point was concerned about the situation of poor people in his home town.
"My goal was to display him, to show him as somebody that was between the black and the white. My goal was to find the grey area, that's what makes us all human beings, you know what I mean?
"It was a very intense experience. But at the same time I feel relieved, not having to carry that character with me any more."
