SAN FRANCISCO (AP) — Federal prosecutors in California are announcing a coordinated crackdown on many of the state's medical marijuana dispensaries Friday.
The move signals an escalation of the ongoing conflict between the U.S. government and the nation's burgeoning medical marijuana industry.
California was the first state to pass a law legalizing marijuana use for patients with doctors' recommendations.
The four U.S. attorneys in California are refusing to provide details of the crackdown in advance. But at least 16 pot shops received letters this week warning face they would face criminal charges if the dispensaries do not shut down in 45 days.
The move comes a little more than two months after the Obama administration toughened its stand on medical marijuana.
