UK legal status key
Legal to possess — not a controlled drug, no prescription needed
Prescription-only medicine — legal, but UK supply needs a prescription
Controlled drug — possession or supply restricted under UK law
Colours show UK legal status only — not safety, effectiveness, or a recommendation to use.
