hemp

There are broadly three groups of Cannabis varieties being cultivated today:

• Varieties primarily cultivated for their fiber, characterized by long stems and little branching, called industrial hemp 
• Varieties grown for seed from which hemp oil is extracted
• Varieties grown for medicinal or recreational purposes.

A nominal if not legal distinction is often made between hemp, with concentrations of the psychoactive chemical THC far too low to be useful as a drug, and Cannabis used for medical, recreational, or spiritual purposes.
