What the statuses mean

Under review
Actively before the FDA advisory committee; a decision is pending and the status can move.
In limbo
Nominated or removed from a restricted list but NOT approved - the headline implies a change, but the legal reality did not move.
Restricted
Prescription-only, banned, controlled, or under active FDA enforcement.
Compounding-legal
On the FDA 503A bulk-substances list; a licensed pharmacy may compound it. This is not the same as being an FDA-approved drug.
Unscheduled
No specific federal action; unaddressed at this time.

Status is never reduced to “legal / illegal.” Each badge pairs a color with a word, and every entry links to the primary source behind it. How we track it.
