At a rally on Sunday in Madison, WI, Democratic presidential candidate and Vermont Senator Bernie Sanders reiterated his support for marijuana decriminalization at the federal level.

“We can argue about the science and the pluses and minuses about marijuana, but everybody knows marijuana is not a killer drug like heroin,” Sanders said,  “And that is why I have introduced legislation to take marijuana out of the federal Controlled Substances Act. It should not be a federal crime.”
