Now that marijuana is officially legal in Colorado, it’s hard to imagine why there were so many years of fuss over a little green plant that happens to make you hungry, giggly or tired. Psychoactive plants are very common in nature, and while cannabis isn’t known for much else besides its effects on the brain, many legal plants used for mundane purposes have little-known mind-altering properties — and they’re growing in parks, gardens, windowsills fields and forests across Colorado. We cannot recommend eating, tasting or smoking any of these — not only because of their psychoactive properties but because in many cases psychoactive plants produce poisons as well (which might be why they were never popularly used or known as recreational drugs). But in the spirit of knowledge and fun, here are a few plants you’ve probably seen, used or even grown without realizing their little secret. . Coleus

Coleus One of the most popular ornamental annuals grown for colorful leaves, the Coleus plants you’ll find in every nursery or garden center in town were bred from plants once smoked by the Mazatec people of Mexico as a mild hallucinogen.

Morning Glory The morning glory family has several sub-families and hundreds of species (including sweet potatoes), and many different types of morning glories are psychoactive. The most familiar morning glory — grown in gardens as a blooming vine that wraps itself up fences and sunflower stalks — has hallucinogenic seeds.

Lettuce Believe it or not, the harmless salad greens you know as lettuce produce psychoactive compounds similar to opium, which can make you feel calm, relaxed and hungry — so that’s why salads are used as an appetizer! The lettuce cultivated today has such a small amount of the psychoactive compounds that it’s impossible for them to have an effect on someone; an analogy for lettuce is industrial hemp, with negligible THC. But wild lettuce as well as the ancient lettuce that modern lettuce was bred from might indeed create a high.

Absinthe Wormwood

Absinthe Wormwood

Brought to Colorado as a medicinal plant, Absinthe Wormood, or Artemisia absinthium, is now an invasive species across the plains, growing wild on roadsides and recently disturbed soils, and is still grown in gardens as an herb. Used to make absinthe — which was banned in the U.S. until 2007 — wormwood is probably only mildly psychoactive at most, since the key component, a chemical called thujone, is also found in many common plants: yarrow, junipers, oregano, sage, hyssop, rosemary and savory, among others. . Mosaic Plant

Mosaic Plant Mosaic Plant is grown as an annual or houseplant in Colorado and can grow year-round in frost-free parts of the United States. Native to South America, Fittonia albivenis is a hallucinogen that has been used by indigenous people for medicinal or spiritual purposes.

Opium Poppy The poppy seed used in muffins and cookies as a culinary spice is in fact from Papaver somniforum — the famous opium poppy. There are many ornamental garden versions, too. The seeds don’t contain opium, but the plants can produce it in the sap that drains from scratched seed pods (which, by the way, is illegal to do with your poppies).

Joint Fir Also known as “Mormon tea,” Ephedra is a genus of desert shrubs that produce ephedrine, a stimulant that has been used medicinally but has been banned by the FDA for adverse side-effects (the plant itself is not illegal). Three Ephedra species grow wild in Colorado and are common in gardens around Denver.
