title: The physical and chemical features of Cannabis plants grown in the United Kingdom of Great Britain and Northern Ireland from seeds of known origin.
abstract: Cannabis plants have been grown in the United Kingdom of Great Britain and Northern Ireland from seeds taken from seizures of cannabis of known geographical origin and chemistry. The gross physical appearance and cannabinoid patterns of many of the cannabis samples produced in the United Kingdom were closely related to those of the parents. However, some notable exceptions were recorded. There were wide variations in actual tetrahydrocannabinol content between plants grown from different seedstock and rather smaller variations within the groups grown from the same seedstock. Cannabis produced in the united Kingdom and higher tetrahydrocannabinolic acid/tetrahyrocannabinol ratios than imported material.
