DEVIL'S WEED
OUTSIDE MY DOOR

If you're of a certain age you probably read one or all of Carlos Castaneda's books, particularly The Teachings of Don Juan: A Yaqui Way of Knowledge, first published in 1968. The Yaqui people originally lived in the northwestern Mexican state of Sonora and part of Arizona. Don Juan was a brujo, or witchdoctor, who taught the narrator of the book how to refine his awareness of the Universe. It's unclear how much of Castaneda's writings are real or pure fantasy, and also it's unclear whether there was a real Don Juan.

Don Juan used hallucinogens as part of his practice, and one of the most powerful he called Devil's Weed, sometimes also called Toloache. These names can apply to various species of the genus Datura. In English we call the Daturas jimsonweeds. Don Juan's jimsonweed probably was DATURA INOXIA. Five blossoming plants of Datura inoxia grow right outside my door as I type this, right in the center of my field of vision when I look outside, standing there as if they were waiting for me. Right now I go photograph one so you can see.The picture is below:

Datura inoxia

That glowing, white blossom at the plant's head is 6.5 inches (16.5 cm) high. Surely someone threw seeds there, for I seldom see the plant elsewhere. Each dawn each datura plant bears one or two blossoms, which wilt by late morning. Each dawn, it's like being greeted by five gnomes, half smiling, half malicious- looking, playing white violins, somberly, soporifically.

Folks here regard the plants as young Angel's Trumpets, which are the small trees with very large, white, drooping flowers I introduced in this year's January 19th Newsletter. Angel's Trumpets are members of the same family as Datura inoxia, the Nightshade/ Tomato Family or Solanaceae, and also are poisonous and hallucinogenic, but they are an entirely different species.

Like me, Don Juan had mixed feelings about Devil's Weed:

She is as powerful as the best of allies, but there is something I personally don't like about her. She distorts men. She gives them a taste of power too soon without fortifying their hearts and makes them domineering and unpredictable.

If you Google Datura inoxia you'll find as many warnings about poisoning as you will mention of the plant as hallucinogenic. One reason is that the dosage needed to feel the effects is pretty close to that which poisons, and it's very hard to judge the active ingredients' concentrations in wild plants.

I have instructions on exact preparation of the plant, but I'm not interested in concocting a dosage for the same reason I'm also against drunkenness and being a pot-head: Brains are the only resource we humans have to keep us from blindly destroying Life on Earth. If we screw up our brains, there's less chance we'll survive.
