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."
