Marijuana might have a friend in Hillary Clinton.

During a town hall on ABC's TV show "Good Morning America" on Thursday, former Secretary of State Hillary Clinton said it is "wrong" that marijuana is categorized as a Schedule I drug and if she became president she would support medical marijuana, allow for research, and support state's rights to continue experimenting in legalization.

Evan Nison, cannabis entrepreneur and the youngest member of NORML, the National Organization for the Reform of Marijuana laws, asked Hillary Clinton if she would vote "yes" or "no" to legalize pot in her own state.

Clinton said she would need to study the language of any bill first, but in general Clinton says she is in favor of reforming the strict laws surrounding the plant.

Clinton said that if elected president, she wants to move marijuana off Schedule I. "We have enough anecdotal evidence about what marijuana can do for medical conditions and easing pain," she said. "I am 100 percent in favor of medical marijuana, but I want to know what the evidence is."

When asked if she supports an adult use market like Colorado's, Clinton was a little less definitive.

"I am also someone who believes states can be those laboratories of democracy, so I am watching carefully the states that have legalized it to learn from them so we can base the best policy on that," Clinton says.
