By section 6 of the Misuse of Drugs Act 1971 it is an offence to cultivate any plant of the genus cannabis in the United Kingdom without a license from the Secretary of State. Anyone committing an offence contrary to this section may be imprisoned or fined, or both. Please note therefore that germination of seeds bought from the Seedsman website without an appropriate license is illegal in the United Kingdom.
