Hemp is one of the most versatile crops on the planet, with practical applications spanning food, clothing, construction, skincare, animal care, and environmental cleanup. Since the 2018 Farm Bill removed hemp from the controlled substances list (defining it as cannabis containing no more than 0.3% THC by dry weight), interest in its uses has exploded. Here’s a practical look at what you can actually do with it.
Eat It
Hemp seeds, often sold as “hemp hearts” once the outer shell is removed, are a nutritional powerhouse. Per 100 grams, they contain about 30 grams of protein and 50 grams of fat, with over 70% of that fat coming from polyunsaturated fatty acids. The ratio of omega-6 to omega-3 fatty acids sits at roughly 3:1, which lines up with recommendations from the European Food Safety Agency. These are essential fats your body can’t produce on its own.
Hemp hearts have a mild, slightly nutty flavor and are easy to work into meals. You can eat them raw by the handful, sprinkle them on salads or yogurt, blend them into smoothies, or use them as a substitute for oats in a breakfast porridge with coconut or almond milk. They work just as well stirred into soups, tossed over grain bowls, or baked into energy bars. Because they’re soft and don’t require cooking, they’re one of the simplest plant proteins to add to your diet.
Use It on Your Skin
Hemp seed oil has a comedogenic rating of zero, meaning it won’t clog pores. It’s a lightweight, dry oil that absorbs quickly without leaving a greasy residue, making it suitable for oily and acne-prone skin types. The same omega fatty acid profile that makes hemp seeds nutritious also helps the oil soothe irritation, support the skin’s moisture barrier, and reduce dryness. You’ll find it as a standalone face oil, a carrier oil for essential oils, or as an ingredient in commercial moisturizers, lip balms, and body lotions.
Build With It
Hempcrete is a biocomposite made by mixing the woody inner core of the hemp stalk (called “shives” or “hurds”) with a lime-based binder and water. It’s not a structural material, so it won’t replace load-bearing concrete, but it excels as insulation and wall infill. Hempcrete provides an R-value of roughly 2.4 to 4.8 per inch, comparable to straw or cotton insulation. For context, standard concrete offers just 0.1 to 0.2 per inch, making it essentially useless as an insulator.
Beyond thermal performance, hempcrete is breathable, naturally regulates humidity, and resists mold. The environmental case is strong too: the hemp plant absorbs carbon as it grows, and the lime binder continues to absorb CO2 as it cures, making hempcrete walls a form of carbon storage rather than carbon emission.
Wear It
Hemp fiber produces a durable, breathable textile that softens with each wash. It has natural resistance to mold and UV light, which gives hemp clothing a longer lifespan than many alternatives. The environmental advantage over cotton is significant. A comparative study across 28 published sources found that hemp requires 38% less water overall than cotton, has a 60% lower water footprint, and needs 91% less irrigation. Cotton remains the dominant natural textile fiber, but it’s one of the most water-intensive crops in the world, requiring roughly 20,000 liters per kilogram of usable fiber according to World Wildlife Fund data.
Hemp fabric blends well with cotton or silk to balance durability with softness. You’ll find it in t-shirts, jeans, jackets, bags, shoes, and upholstery. The fiber also works for rope, twine, and canvas, which were among hemp’s earliest industrial uses.
Make Paper From It
Hemp produces paper-grade pulp far more efficiently than trees. One acre of hemp yields as much pulp as roughly four acres of forest over a 20-year cycle, because hemp can be harvested multiple times per year while trees take decades to mature. Hemp paper is also naturally acid-free, which means it resists yellowing and deterioration over time. Specialty applications include archival paper, cigarette papers, filters, and packaging materials.
Replace Plastic With It
The cellulose in hemp stalks can be processed into bioplastics that break down far faster than conventional petroleum-based plastics. In controlled soil burial tests, hemp fiber lost 44.5% of its mass in just 11 days of exposure to soil microorganisms. For comparison, polylactide (a common plant-based bioplastic often marketed as compostable) lost only about 4% of its mass over the same period. Hemp-based plastics show up in automotive panels, packaging, 3D printing filament, and consumer goods like sunglasses and phone cases.
Bed Animals on It
Hemp shives make excellent bedding for horses, chickens, rabbits, and other livestock. The material can absorb up to five times its own weight in moisture, which is typically 50% more absorbent than wood shavings. Even more useful is its ability to control odor: hemp bedding absorbs about 50 to 60% of ammonia, compared to 44% for wood shavings and a mere 4% for straw. It’s low-dust, composts easily, and maintains a moisture content similar to commercial wood shavings at around 7 to 8%.
Clean Contaminated Soil
Hemp is a proven tool for phytoremediation, the process of using plants to pull contaminants out of polluted ground. The plant can absorb high concentrations of cadmium, nickel, lead, chromium, zinc, copper, and selenium from contaminated soil. It also takes up pesticides, solvents, explosives, and polyaromatic hydrocarbons.
The most famous example dates to 1998, when hemp was planted on agricultural land contaminated by the Chernobyl nuclear disaster. It successfully removed soil contaminants from those fields. In 2008, hemp was grown near a steel plant in Italy to leach dioxin from surrounding farmland. The metals concentrate most heavily in the roots, which means the above-ground portions of the plant can sometimes still be used for industrial fiber while the roots do the cleanup work below.
Other Practical Uses
Hemp oil works as a base for paints, varnishes, and wood sealants. The seeds can be pressed into cooking oil or processed into hemp milk. Hemp fiber reinforces composite materials in the automotive industry, where companies use it to reduce the weight of door panels and dashboards. The flowers and leaves of compliant, low-THC hemp plants are used to produce CBD extracts for tinctures, topicals, and edibles. Even the dust and short fibers left over from processing find use as garden mulch and soil amendment.
With a single fast-growing crop producing usable seeds, fiber, and woody core material, hemp offers something unusual: almost every part of the plant has a commercial or practical application.
