California doesn't care about what's legal or not, they've legalized selling weed which is still super illegal (federally, which is what we're talking about).
Exactly. While someone in CA was probably able to access hemp items (and straight out pot items obviously) it was still illegal to produce. That doesn't mean you couldn't obtain it through mail orders or lax enforcement, but I mean I can go buy heroin from a guy I know, that doesn't make it legal.
I wouldn't say that California's legalization of marijuana sales indicates a general disregard for the law in California, considering multiple states across the country have the same laws and California wasn't even the first to do it.
