Originally and hereditically there wasn’t a lot of difference between hemp and marijuana, but years of breeding and manipulation resulted in the emergence of two varieties: one for spiritual purposes and the other for industrial uses.
The marijuana plant has a high tetrahydrocannabinol (THC) content, while hemp’s seeds and fibers contain low levels of THC and high levels of cannabidiol (CBD).
Marijuana plants tend to grow shorter and wider than hemp. Farmers typically want to give marijuana as much growing room as possible so the plants can spread, unlike hemp, which has a priority to produce strong fibers for manufacturing purposes.
Cannabis wins in a popularity contest because of its ability to provide a euphoric effect when ingested, but hemp — sitting quietly in the background – is less controversial and provides both medicinal and industrial benefits.
The main reason that these two plants are separated is because marijuana is a horticultural crop grown for its THC content, while hemp is an agricultural crop grown for its CBD content and seeds & fibers.
A big victory came for hemp and CBD after passage of the U.S. Farm Bill in 2014, enabling cultivation by state departments of agriculture and higher-education institutes. But now in 2017, hemp is officially legal to cultivate and distribute across all 50 states.
Marijuana's psychoactive effects put it on the "most dangerous drugs" list, but CBD is not psychoactive, as well as being a highly versatile crop, and innovators continue to jump at the opportunity to create new products from the plant.
Both marijuana and hemp are booming industries for quite different reasons. Medterra is a CBD company based in Kentucky. Their hemp is locally grown and cultivated, and then high-quality CBD is harvested from the plants. Medterra has 4 successful products on the market right now.
