LAKE FOREST, Calif. (AP) - Pot shops appear to be closing as a result of a California crackdown on medical marijuana.
 
All eight collectives that occupied the second floor of an Orange County mini-mall have closed since California's four U.S. attorneys announced about two weeks ago that they were cracking down on dozens of operations across the state growing and selling medical pot illegally.
 
Across the Central District of California, many of the 38 clinics have closed because landlords were given just 14 days to evict their clients. That period that expires Friday.
 
Some smaller California communities have struggled in recent years to regulate the clinics, while others have banned pot shops altogether. The fight has cost local municipalities millions of dollars in legal fees. Frustrated and fed-up with pot collectives flouting their laws, cities asked the federal government for help.
 
California law allows the drug to be cultivated and supplied to ill people on a nonprofit basis. Pot remains illegal under federal law.
