Sativex
Sativex (nabiximols) is a prescription-only cannabis-based medicine used to treat moderate to severe spasticity in multiple sclerosis. Although it contains controlled substances (THC and CBD), it is not treated like traditional cannabis or other high-risk controlled drugs.
Instead, Sativex has a unique legal classification: it sits in Schedule 4 Part 1 of the Misuse of Drugs Regulations 2001, but with some extra rules not normally applied to other drugs in that category.
