The feds have made "legalized" selling a major inconvenience in California. They've raided the outlets, threatened landlords, audited employees, and just been a real pain in the rectal area about it.
A friend who happens to be a landlord was sitting in a coffee shop in L.A. and some guy in a suit sat down at his table and flashed a badge for a second, too fast for him to read it, and then proceeded to tell him how the "federal government is going to ruin his life if he didn't cancel the lease on the new medical marijuana store" he had just signed a lease on. He had just rented the space out after it was empty for over 2 years and he decided to cancel the lease but allow them to stay on a month to month basis. Technically he complied to the suit's orders, but he's sweating every time he sees someone in a suit come into his office.
