Why this term matters

One of the most common patient-facing dosage forms.

UK medical cannabis context

NHS public guidance explicitly distinguishes prescribed products from shop-bought CBD or hemp oils.

What not to assume

Products sold as “CBD oil” in shops are not the same thing as prescribed cannabis-based medicines.

Careful wording: Avoid using “oil” as though it automatically means legal, prescribed or clinically evaluated.
