Whether it’s grown for fiber, grain or even cannabidiol — more commonly known as CBD — the plants are often lumped together in regular, and even rule-making, conversations. And recent legalization of medical marijuana and the ongoing debate surrounding recreational use can muddy the waters further.
How is hemp different from marijuana?
If over the limit, the crops are burned, resulting in a total loss because no crop insurance is available in South Dakota. As of early October, no fields tested have gone over the limit, Derek Schiefelbein, the DANR industrial hemp program manager, said.
Is growing hemp for fiber and hemp for CBD the same?
There’s no doubt that hemp has a stigma in South Dakota.
Under the terms of the most commonly issued “low THC industrial hemp licence” farmers are only allowed to harvest the stems and seeds of the hemp plant (a type of cannabis).
But he has to import his key ingredient from America, a situation he describes as “insane”.

In addition to oils and balms, the company has run CBD yoga and massage as well as developing edible products such as CBD brownies, CBD gummy sweets, and even CBD prosecco.
The UK CBD market is big business and growing rapidly. Products containing it are taken by people with a variety of ailments from chronic pain to anxiety and depression.
Published in the journal New Phytologist, the researchers found that high-CBD plants inherit about 90% of their genes from drug-type cannabis and the rest from hemp. Traditionally, cannabis plants are split into two varieties: a drug-type grown for psychoactive or intoxicating properties (i.e., marijuana) and a hemp-type used to make industrial products like fiber.
“This poses a challenge, though,” said study co-author and CBS graduate CJ Schwartz of Sunrise Genetics. “The genes that allow for the production of CBD are also a bit ‘leaky.’ This can result in about 5% of the product ending up as THC instead of 100% CBD.”
The researchers examined different types of cannabis, including drug-type varieties that produce large amounts of psychoactive tetrahydrocannabinol (THC). Plant breeding has increased the THC level to the point where it can account for up to a quarter of a plant’s total weight. The scientists found that breeding high-THC plants with hemp-type plants can swap a few genes and make a new plant that produces high levels of CBD instead.
“Over the past decade, we’ve seen a surge in demand for CBD and we wanted to better understand how plant breeders created high-CBD plants to meet rising demand,” said study co-author George Weiblen, who is a professor in the College of Biological Sciences (CBS) and the science director at the Bell Museum.
