Industrial hemp is a variety of Cannabis sativa and is of the same plant species as marijuana. However, hemp is genetically different and distinguished by its use and chemical makeup. Industrial hemp refers to cannabis varieties that are primarily grown as an agricultural crop. Hemp plants are low in THC (delta-9 tetrahydrocannabinol, marijuana’s primary psychoactive chemical). THC levels for hemp generally are less than 1 percent. Federal legislation that would exclude hemp from the legal definition of marijuana would set a ceiling of 0.3 percent THC for a cannabis variety to be identified as hemp. Marijuana refers to the flowering tops and leaves of psychoactive cannabis varieties, which are grown for their high content of THC. THC levels for marijuana average about 10 percent but can go much higher.
