Yes — cannabis seeds are legal to buy and sell in the UK.

So while purchasing seeds is legal, cultivation is not permitted without proper licensing.

Produce THC once cultivated
Are classified as a Class B controlled drug
Require a Home Office licence to grow legally
This distinction is why you may see seeds openly sold online in the UK.
