All US localities are subject to federal law. Federal law enforcement is not currently enforcing the law in some situations, but the law remains on the books and still is enforced in many situations.
If you toss in those under the UCMJ and other people on federal property, etc, I'd say weed laws are federally enforced against the majority or a hair under it.
For such persons there is still actively enforced 10 year jail sentence for being a pot user.
Not to mention all sorts of weird state exceptions. In my state they have legal weed but also a law that says ANY metabolites in your body is a DUI. Inactive metabolites stay in the body a long long time and surviving here on the abysmal public transport without driving would be quite unpleasant. So basically just as illegal as it ever was.
It's hard to understand how a nation can pride itself in being the 'land of the free' while having such dystopian law enforcement. They apparently pick you up and drive you home if you're underage and out too late as well. Kids can shoot guns but they basically control every other aspect of your life. And you better not get into an argument with them or you may be assaulted, it's like dealing with the Sturmabteilung.
