‡ Cannabis sativa
Indian hemp or marijuana (not to mention pot, dope, spliff, skunk etc). Delicate fronds made the plant a Victorian border essential; but you can also suffer extreme hallucinations or even death if you sleep in a cannabis field. Known as the “cementer of pleasure” and the “leaf of delusion”, it can only be grown with a Home Office licence
I think the author may have been eating too much laburnum anagyroides.
Although, I suppose you could make the case that sleeping in a field of cannabis could cause death… by law enforcement.
