Talking to MTV News, the director revealed that while Savages centres on an extreme situation, it is not inconceivable that such a thing could happen.
"We have quite a ride," Stone explained. "It is set in a drug war. It's set in California, and we have a new burgeoning industry here with young independent growers. It makes sense. It's a hypothetical situation; it could happen."
Stone went on to voice his support for the legalisation of marijuana, as he believes that such a law would save lives and decrease much of the violence happening in the world.
"I think it's a tragedy what has happened, and I saw it coming 40 years ago, and it keeps going. And of course politicians keep making election promises. It's an easy subject to win votes on," he said.
"At the same time, a lot of money gets involved, and it's built up into a huge industry in America and in Mexico, where we have criminal justice that has been perverted. We have victimless crimes all over our jails: 50% of our jail population is involved with victimless crimes, most of them with drugs.
"Money gets made by the prisons and the precept will take them private, you know that, and the politicians win votes, the prosecutors, the judges, the bailiffs, everything. It's like the Pentagon: It never stops when you start."
Savages stars Blake Lively, Taylor Kitsch, Aaron Taylor-Johnson, John Travolta, Uma Thurman and Salma Hayek.
It opens in the US today (July 6), and debuts on September 28 in the UK.
