DISTRICT OF COLUMBIA: The new leader of the Drug Enforcement Administration said Tuesday heroin probably is more dangerous than marijuana, diverging in tone from his embattled predecessor.

Acting Administrator Chuck Rosenberg, a former prosecutor whose stance on drug reform is somewhat of a mystery, also said his agents are not prioritizing marijuana enforcement — though he’s not ordered them off it.

The statements, made on a morning conference call, were far from an endorsement of marijuana, which four states allow for recreational use and many others do for medical purposes.

“If you want me to say that marijuana’s not dangerous, I’m not going to say that because I think it is,” Rosenberg said. “Do I think it’s as dangerous as heroin? Probably not. I’m not an expert.”
