Federal law still enforced against the ~44% of the population who have constructive possession of a firearm by virtue of owning one themselves or having access to one via living with someone else with one and it either being unlocked or locked in a way other adults in the house may be able to get to it.

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.
