But Eugene Jarecki, whose film "The House I Live In" documents what he says is the complete failure of America's war on drugs, said supporters of decriminalized weed shouldn't get too overjoyed yet. There's still a long way to go.
"I have a larger fear about these decisions which is that any system in need of a complete overhaul is like a pot on a stove full of water that has a cover," Jarecki told The Huffington Post. "Because the steam can't get out, it has to explode. The danger with these small victories is that they can get mistaken for larger-scale victories. But if that happens, then the steam gets let out a little bit and it just kind of kicks the can down the road for when the pot will explode."
In Jarecki's film he claims the drug war has resulted in 45 million arrests in the last 40 years, costing state, local and federal officials an estimated $1 trillion.
Still, the film says drug-use rates remain as high as they were when President Richard Nixon began the battle in 1971.
Jarecki isn't content with seeing a couple states legalize the use of one drug, he said. He'd like to see America embark on a path similar to the one already traveled by Portugal, which decriminalized all drugs in 2001, with spectacular results, according to the reform's supporters.
But Jarecki added that this year's election victories for legal pot are far from insignificant.
"Every small victory like a Colorado, Washington or California is crucial in one way because it demonstrates where public thinking is and demonstrates vulnerability of a system that looks so invulnerable," he said.
It remains to be seen whether President Obama will let the states' new laws go unchallenged by the federal government.
The Obama administration has already waged a large-scale war on medical marijuana in California. Shortly after the new initiatives passed, a DEA spokesperson made clear "the Drug Enforcement Administration’s enforcement of the Controlled Substances Act remains unchanged."
Obama is at the helm of a nation facing stubbornly high unemployment, paralyzing inequality and a still raging war in Afghanistan. Jarecki said he hopes the president will focus on more important matters than state pot laws.
"With so much on his plate that are real areas of overwhelming American need, the quibbling between federal law and state law with respect to marijuana seems a waste of time and seems woefully unproductive," Jarecki said.
The filmmaker also said the new measures provide even more evidence that the deeply unpopular drug war has been rejected by the majority of Americans.
"The laws create case studies where America will learn what Portugal learned a long time ago, which is that legalizing drugs does not have the negative affects that proponents of the drug war say it will have," Jarecki said. "It stands to reason that [Congressional lawmakers] need this to be demonstrated to them."
