10 Mind-Altering Plants You Can Cultivate in Your Own Space

Cannabis reigns supreme as the ultimate DIY drug. It requires minimal effort and expertise to grow, and its legal status varies by region—either fully permitted or loosely regulated. Who would go out of their way to trouble someone over a few plants in their garden? (Though, I acknowledge, that might be optimistic.) Even without outdoor space, a small closet can suffice for personal cultivation, and numerous companies offer starter kits to simplify the process. Many users appreciate the unique effects cannabis delivers.

Consuming Salvia divinorum, also known as 'diviner's sage,' either by chewing or smoking its leaves, induces a brief but powerful psychedelic effect. While some find it enjoyable, others dislike the experience. Regardless, cultivating this plant is straightforward. Salvia reproduces through cuttings rather than seeds, and you can purchase it online or at garden centers. As a semi-tropical perennial, it thrives with ample water and cannot tolerate cold temperatures, making indoor growth necessary in certain climates. Its flowers are also quite attractive.

It’s fascinating how heroin, one of the most potent drugs, originates from the delicate poppy flower. While growing opium poppies is simple, producing opium or heroin from them is fraught with legal and practical challenges. You can purchase poppy seeds on Amazon or at local garden shops, or even salvage them from baked goods. Growing poppies for their blooms is entirely legal, but extracting narcotics from them is highly illegal. Additionally, producing heroin at home is impractical—it requires 10,000 to 12,000 seed pods to yield just one kilogram. This explains why homegrown heroin is rare in the U.S., though it’s not unheard of.

Currently trending, psilocybin mushrooms are relatively easy to obtain in many areas if you have the right connections. Alternatively, you can cultivate them yourself, though this may involve legal risks depending on your location. Growing mushrooms differs from typical plant care since they belong to the fungi kingdom. The basic process involves introducing spores to a growth medium, adding nutrients, and allowing time for development. However, the process can be complex. This video provides a straightforward guide for beginners—requiring only a bag of rice and some spores to get started.

The beauty of cultivating plants for their psychoactive properties is that almost anything you grow can have an intoxicating effect if you’re determined enough. Take the humble dandelion, for instance. These resilient plants thrive in almost any environment, often without any encouragement. Their flowers can be transformed into dandelion wine by adding sugar and yeast and allowing time for fermentation. While the taste might not be appealing, the wine will undoubtedly have an intoxicating effect. Similarly, many other plants, such as grapes, can be fermented to create wine, beer, or spirits.

Certain varieties of morning glory plants produce seeds containing ergot alkaloids, compounds chemically akin to LSD. While growing morning glories in your garden is legal, consuming their seeds for psychoactive effects is risky. Achieving a high requires ingesting a large quantity of seeds, and dosage control is notoriously difficult. Overconsumption can result in severe physical reactions, including seizures or even death. Additionally, the long-term effects of regular use remain largely unknown.

Cultivating kava at home is no small feat for amateur gardeners. The plant demands highly specific conditions to flourish. Ideally, it requires nutrient-rich soil, an elevation of 500 to 1000 feet above sea level, and a tropical climate. It thrives in shaded areas with loose soil, ample water, and high humidity. If you manage to replicate these conditions indoors for three years, you can harvest the roots to brew kava tea. However, the effects are subtle—often leaving you wondering, ‘Am I slightly more relaxed?’ Given the effort involved, the payoff may not seem worth it.

Jimsonweed, scientifically known as Datura stramonium, belongs to the nightshade family, which should serve as a warning about its potential dangers. It is highly toxic and should never be consumed for recreational purposes. Ingesting Jimsonweed can lead to severe convulsions, hallucinations, and even death. Survivors report terrifying, prolonged hallucinations lasting up to three days—far from the pleasant, psychedelic experiences associated with mushrooms. Despite its toxicity, Jimsonweed is easy to cultivate, requiring minimal care and no fertilizer, as long as it’s protected from cold temperatures. Its flowers, however, are undeniably beautiful.

The psychoactive potential of wormwood depends on how you define 'getting high.' It contains thujone, a compound that can be toxic in large doses, potentially causing seizures or even death. However, in smaller amounts, it’s believed to have medicinal and mild psychoactive properties. Wormwood has been used in traditional remedies across various cultures and is a key ingredient in beverages like vermouth and absinthe. Absinthe, often associated with hallucinations, likely owes its effects to its high alcohol content rather than wormwood itself. Growing wormwood at home is straightforward, and plants are readily available online or at garden centers.

While catnip may not have much effect on humans, it’s a favorite for feline friends, making it a great addition to your herb garden. Consider planting it outdoors and letting your cat enjoy rolling around in it—they’ll be thrilled! The effects of catnip typically last around ten minutes, followed by a 30-minute period where cats become temporarily immune to its allure. Interestingly, catnip also affects larger felines like lions, leopards, and jaguars.
