Poor hemp. As soon as you mention it, people’s ears perk up and they immediately think of marijuana. It’s illegal to grow hemp in the United States, so there must be something wrong with it, right?

• Both hemp and marijuana come from the same species- Cannabis sativa. However, one species can include countless varieties (depending on which botanist you ask!). In this case, hemp has been cultivated for at least 12,000 years, with selection being for fiber and seeds . The useful parts are the stalk (fiber) and the seeds (oil content). In marijuana, selection has been for flowers with a high THC (tetrahydrocannabinol) content. THC is what makes a person “high.”
• THC values for marijuana are about 15-20%. THC values for industrial hemp are about 0.3% . No matter how much hemp a person smokes, they will not get high.
• If industrial hemp were grown near marijuana, cross-pollination would be inevitable, contaminating and reducing the THC content of the marijuana. What a boon to the war on drugs that would be!
  

So we can safely lay to rest the notion that growing, buying, and using industrial hemp is in any way akin to growing, buying, and using marijuana. Now, what is so great about industrial hemp fiber?

• Long fibers, which mean longer garment life and more absorbency
• Naturally resistant to mold and UV light
• Grown very close together to encourage tall stalks- this also means that weeds are excluded, eliminating the need for herbicides
• Naturally resistant to most pests, so no need for pesticides
• Leaves the soil nitrogen-rich, rather than depleting nutrients
• Produces 250% more fiber than cotton with much less water
