The Obama administration delivered new guidance on medical marijuana to federal prosecutors Monday, signaling a broad policy shift that will mean fewer crackdowns against dispensaries and the people who use them.
Attorney General Eric H. Holder Jr. instructed government lawyers that in 14 states where medical marijuana use is legal, federal prosecutors should focus only on cases involving higher level drug traffickers or people who use the state laws as a cover story.
