WASHINGTON -- The White House declined to weigh in Tuesday on whether President Barack Obama has changed his position on medical marijuana use after the president's onetime choice for surgeon general, Sanjay Gupta, reversed his stance and apologized for misleading the public on the drug's effects.

During the daily press briefing, CQ-Roll Call reporter Steve Dennis asked White House spokesman Josh Earnest if the administration had any reaction to Gupta's Aug. 9 column, "Why I changed my mind on weed," in which Gupta explores the discrepancy between the Drug Enforcement Administration's classification of marijuana as a Schedule I drug and scientific research demonstrating its benefits. Gupta, who serves as CNN's chief medical expert, not only apologized for dismissing the evidence from medical marijuana patients, but said he had concluded that marijuana has a low potential for abuse and "very legitimate medical applications."

Dennis also asked if Obama had personally been looking at the issue, given that national polls show rising support for marijuana legalization since he took office.

Earnest ducked the question, responding, "I have to confess I did not see the Sanjay Gupta column you're referring to, so it's hard for me to comment at this point."

The Obama administration has cracked down hard on medical marijuana, even in states that have legalized its use. A recent report found that this administration spent nearly $300 million on medical marijuana intervention through lawsuits, indictments and asset forfeiture attempts by the Justice Department. Over the past few years, the Internal Revenue Service has also targeted medical marijuana dispensaries, forcing many of them to the brink of closure, and largely ignoring the fact that many such businesses were in compliance with state laws.

But as the White House continues to wage war on pot, public opinion has shifted in the opposite direction. A HuffPost/YouGov poll conducted in April found that 51 percent of Americans said marijuana should be "legalized, taxed and regulated like alcohol." An earlier Pew Research Center survey also found majority support among Americans for marijuana legalization.

"It's baffling that the White House still seems so afraid to embrace this issue, particularly for an administration headed by a former marijuana enthusiast who repeatedly pledged during the 2008 campaign to put a stop to federal raids on state-legal providers," Tom Angell, co-founder of the pro-legalization website Marijuana Majority, told The Huffington Post in a statement. "Polls show that legalizing marijuana is a mainstream issue and that a super-majority of voters wants the feds to let states implement their own marijuana laws without harassment. There's almost no one clamoring for a continued federal crackdown, so I can't imagine why the president hasn't put a stop to it yet."

Obama has previously shown significant confidence in Gupta's medical expertise: As many observers recalled, the president reportedly offered him the post of surgeon general in 2009. Gupta then withdrew his name from consideration, citing his reluctance to give up his medical practice and be away from his family.

    Former President Bill Clinton

    Bill "Didn't Inhale" Clinton has supported decriminalizing marijuana for more than a decade and more recently has spoken out against the war on drugs.

    “I think that most small amounts of marijuana have been decriminalized in some places, and should be," he said back in 2000 in an interview with Rolling Stone. "We really need a re-examination of our entire policy on imprisonment.”

    He's since spoken about the issue of marijuana and drug prohibition a number of times. Last year, he appeared in the documentary, "Breaking the Taboo," where he argued that the war on drugs has been a failure.

    Paul exhibited his libertarian tendencies earlier this year when he explained that he'd favor reforming marijuana laws to either decriminalize or reduce penalties for possession.

    “I don't want to promote that but I also don't want to put people in jail who make a mistake," Paul said. "There are a lot of young people who do this and then later on in their twenties they grow up and get married and they quit doing things like this. I don't want to put them in jail and ruin their lives."

    Former Rep. Ron Paul (R-Texas)
    As a congressman, Paul took his opposition to marijuana and drug prohibition a step farther than his son has so far. He supported a number of bills that would have removed the plant from its current status as a Schedule I substance under federal law, where it is considered alongside heroin and PCP. Because his history on the topic is so expansive, just take a look at the video to the left for a selection of his comments.

    While the 83-year-old Robertson may say a lot of things that make him sound like a kooky old man, he's also made a few remarks to endear himself to marijuana advocates.

    "I really believe we should treat marijuana the way we treat beverage alcohol," Robertson said in an interview with The New York Times in 2012. "I've never used marijuana and I don't intend to, but it's just one of those things that I think: this war on drugs just hasn't succeeded."

    Robertson has made similar remarks on his "700 Club" show before, but the Times, like many others, perhaps felt they must have misheard him.

    In a state of the city address earlier this year, Bloomberg made it clear that he supported a promise by New York Gov. Andrew Cuomo (D) to push marijuana decriminalization. "I support Governor Cuomo's proposal to make possession of small amounts of marijuana a violation, rather than a misdemeanor, and we'll work to help him pass it." A similar effort specific to NYC has made some progress, but faces an unclear path forward with New York lawmakers.

    Some may think of Cranston as more of a meth guy thanks to Walter White, his character on AMC's hit show "Breaking Bad," but in real life he's spoken out against current pot laws, suggesting that recreational marijuana use isn't a big deal -- and shouldn't be treated like it.

    “[T]o me, marijuana is no different than wine," he said in an interview with High Times. "It's a drug of choice. It's meant to alter your current state -- and that's not a bad thing. It's ridiculous that marijuana is still illegal. We're still fighting for it ... It comes down to individual decision-making. There are millions of people who smoke pot on a social basis and don't become criminals. So stop with that argument -- it doesn't work.”

    Unlike many politicians, Johnson, a Libertarian presidential candidate in 2012, has unabashedly admitted using marijuana. But beyond his personal history with pot, he's been an outspoken advocate for legalizing and taxing it.

    From his campaign platform:

    "By managing marijuana like alcohol and tobacco - regulating, taxing and enforcing its lawful use - America will be better off. The billions saved on marijuana interdiction, along with the billions captured as legal revenue, can be redirected against the individuals committing real crimes against society."

    King hasn't been shy about advocating for a legal marijuana industry that could give easy access to recreational users and revenue to the states.

    “Marijuana should not only be legal, I think it should be a cottage industry," he said in an interview with High Times. "My wife says, and I agree with her, that what would be really great for Maine would be to legalize dope completely and set up dope stores the way that there are state-run liquor stores.”

    Rohrabacher was a co-sponsor of the 2013 "Respect State Marijuana Laws Act," which seeks to protect marijuana users or businesses acting legally according to state marijuana laws from being prosecuted under the federal Controlled Substances Act.

    While marijuana has been made legal for various uses in a number of states, the Obama administration continues to enforce federal laws across the nation. This has led to numerous raids of marijuana-based businesses, as well as prosecutions of growers and other people involved in pot.

    "I think it's about time we legalize marijuana," he said. "We have to make a choice in this country. We either put people who are smoking marijuana behind bars or we legalize it, but this little game we're playing in the middle is not helping us, it is not helping Mexico and it is causing massive violence on our southern border."

    From an op-ed by Branson arguing for an end to the war on drugs:

    "Decriminalization does not result in increased drug use. Portugal's 10 year experiment shows clearly that enough is enough. It is time to end the war on drugs worldwide. We must stop criminalising drug users. Health and treatment should be offered to drug users - not prison. Bad drugs policies affect literally hundreds of thousands of individuals and communities across the world. We need to provide medical help to those that have problematic use - not criminal retribution."

He's since suggested he'd be willing to support decriminalizing possession of small amounts of marijuana.

    Comedy Central's Jon Stewart
    Stewart has made a habit of taking down politicians who exhibit an uncompromising stance on marijuana prohibition. In 2012, Stewart took New Jersey Gov. Chris Christie (R) to task for vetoing a marijuana decriminalization bill.

    “Alright, as much as I disagree, I don’t think marijuana should be illegal, but it is illegal on the federal level," Stewart began. "Christie is a former prosecutor, a man of conviction, of principle, doesn’t believe that the state should supersede federal law."

    The praise in the second sentence is a good sign that Stewart is about to shred Christie. Watch the rest of his takedown above.

    In an interview with the UK's Daily Mail in 2011, Nicholson said that he personally still used marijuana, before making the case for ending the prohibition on pot as well as other drugs.

    "I don't tend to say this publicly, but we can see it's a curative thing. The narcotics industry is also enormous. It funds terrorism and - this is a huge problem in America - fuels the foreign gangs," he said. "More than 85 percent of men incarcerated in America are on drug-related offences. It costs $40,000 a year for every prisoner. If they were really serious about the economy there would be a sensible discussion about legalization."

    In a 2013 American Conservative op-ed chock full of moderate Republican views, Huntsman snuck in a call to "applaud states that lead on reforming drug policy."

    While Obama and his administration have responded to state marijuana reforms by saying they must enforce federal laws against marijuana, the president has the power to reschedule the drug, which would allow federal authorities to shift resources away from a prohibitive approach.

"If somebody's gonna smoke a joint in their house and not do anybody any harm, then perhaps there are other things our cops should be looking at to engage in and try to clean up some of the other problems we have in society." While Obama has spoken repeatedly about not being interested in prosecuting small-time marijuana users, he hasn't done anything to prevent them from being busted by law enforcement in states where the drug is still illegal.

    “As president 35 years ago I called for decriminalizing -- but not legalizing -- the possession of marijuana,” Carter said. “Since then, U.S. drug policies have been very horrible to our own country because of an explosion in prison populations.”

    “The proof will be in the policy. The war on drugs has gotten a really bad rap, when you ask people if they support the war on drugs they say no ... [Obama's] budget once again has the same old drug warrior policy ... I reject the assumption that everybody who is using drugs needs treatment or is an addict and needs to get arrested ... Not all drug use is abuse.”

"When you look at the disparities in sentencing drug offenders, hasn't this kind of injustice undermined the legitimacy of our criminal justice system?”

    Tancredo continued, “The arguments against marijuana today are the same as the arguments against liquor years ago.”

    Years later, the former congressman agreed to smoke pot on camera with a documentary filmmaker, a deal that he later backed out of.
