I do have an odd mystery about datura, something I thought I saw in a footnote under a poem by Kipling, but have been unable to find since.

The poem is "La Nuite Blanche" in which he describes someone having a very heavy trip - things climbing up the wall etc.

Poem part

Then a Creature, skinned and crimson,
Ran about the floor and cried,
And they said that I had the "jims" on,
And they dosed me with bromide,
And they locked me in my bedroom --
Me and one wee Blood Red Mouse --
Though I said: "To give my head room
You had best unroof the house."

The footnote suggested that the reference to "jims" on, was to jimsonweed, which I understand had travelled to India.

But I have not found anything to back that up.
