What is the difference between hemp and marijuana? Both "hemp" and "marijuana" are the same plant. The differentiation is made for legality reasons. According to the 2018 Farm Bill cannabis plants with less than 0.3% Delta-9 THC and containing higher amounts of CBD, are referred to as hemp or industrial hemp. Plants with higher amounts of THC are referred to as marijuana. Many people are mislead into thinking that hemp and marijuana are different plants, but in reality they're the same plant—cannabis.
Whether a cannabis plant is intoxicating or non-intoxicating is mainly due to genetics. Different cannabis genetics produce different amounts of chemical compounds called cannabinoids. The most abundantly found and used cannabinoids are THC and CBD. Some cannabis plants naturally produce high amounts of THC, causing intoxicating effects. Some plants produce higher amounts of CBD, which don't cause intoxicating effects.
