Male Cannabis Plants: Don't Toss Them, Put Them to Work
Breeding, hash, natural pest repellents and hemp fiber: what a male cannabis plant is actually good for, and whether it's worth smoking.
Male cannabis plants don't produce cannabinoid-rich buds, but they're far from useless: you can use them to breed hybrid seeds, make hash and concentrates, brew natural pest repellents and pull hemp fiber for textiles.
The male cannabis plant is a big deal in any grow. Unlike females, which produce buds loaded with THC and other cannabinoids, males produce pollen sacs whose job is to fertilize female plants and create seeds. They don't give you buds, but males are essential for reproduction and for creating new cannabis strains.
Most growers would rather grow only females to get as many buds as possible. Males don't just skip the buds; they can also tank the quality of your harvest if you don't pull them in time. When a male's pollen sacs accidentally pollinate your females, those females start putting energy into seeds instead of buds. If what you're after is smokable flower, seeds are bad news, because they cut both the amount and the quality of the final product.
How do you identify a male cannabis plant?
To spot male plants, keep a close eye on them in early flowering. Male preflowers are small green balls that look like tiny eggs, with no hairs or other distinguishing features. As flowering goes on, the pollen sacs get bigger and denser, which makes them easy to identify. If you find males, get them out of your grow space fast to avoid accidental pollination.

What are male cannabis plants used for?
Even though males don't make buds, they still have some interesting uses in the cannabis world. Breeders, for example, use male plants to create new strains and to preserve existing ones. Males can also be used to make hash and concentrates. The cannabinoid content of male flowers is generally lower than that of females, but they still contain cannabinoids that can go into cannabis products.
Another interesting use for male cannabis plants is as a natural pesticide. Pest-control extracts and repellents can be made from the dried flowers and leaves of male plants, and research suggests that pure cannabinoids have antibacterial and antimicrobial properties. On top of that, male hemp fibers are finer and softer than female fibers. Male fiber also holds up better to twisting and is more flexible, which makes it ideal for certain textile uses.

Bottom line: a male cannabis plant can be a headache in the grow room, but it still has its uses in the cannabis industry. Growers need to be able to spot and remove males to avoid accidentally pollinating their females. That said, male plants can also be used for breeding, creating new strains, making hash and concentrates, as a natural pesticide and in textiles.
What are the benefits of a male cannabis plant?
Male plants are usually seen as a nuisance in a grow, but they can have a few real upsides.
- First, as we mentioned, the male is essential for reproduction and seed production. By pollinating females, you can produce hybrid seeds with the genetic traits you're looking for.
- Plus, a lot of people think male plants have no cannabinoids at all, and that's not quite true. Their cannabinoid content is usually lower than the females', but male flowers do contain cannabinoids and can be consumed. Just know that male flowers tend to be less potent and taste bitter and unpleasant.
- Another use for male cannabis plants is making hash and concentrates. The flowers, leaves and stems of males can be processed alongside females to make hash and other concentrates.
- The dried flowers and leaves of male plants can even be used to make pest-control extracts and repellents, since research suggests pure cannabinoids have antibacterial and antimicrobial effects.
- Finally, male hemp fibers are finer and softer than female ones, which makes them ideal for the textile and paper industries. These fibers can be used to make clothing, rope and paper, among other products.
In short, male cannabis plants are usually treated as a problem in the grow, but they have a range of uses and benefits. From producing hybrid seeds to making hash, repellents and textile fibers, males can be put to work in all kinds of ways.
What happens if you smoke a male cannabis plant?
Smoking male cannabis isn't exactly popular among smokers. Unlike female flowers, which pack high levels of cannabinoids like THC and CBD, male plants have much lower levels of these compounds, and their THC content is pretty low. So smoking a male plant won't give you the high people are looking for in cannabis.
That said, some people report that smoking male plants gives them a feeling of relaxation and well-being, though that may have more to do with the terpenes and other compounds in the plant than with the cannabinoids themselves. And even though the THC content is low, males still contain some cannabinoids that are being studied for potential health benefits, like CBD and CBG.
Overall, smoking male cannabis isn't common practice, and it's not a great way to get the effects people want from weed. You're better off saving male plants for breeding or other industrial or farming uses.
