Hemp, also called cannabis in Latin, is one of the oldest cultivated and medicinal plants in the world, which can be cultivated in different climate zones and is available in different genetics. Both hemp and hops belong to the Cannabaceae family (hemp plants) .
Hemp can be grown both on the field and “indoor”. The use of the hemp plant and its components (flowers, fibers/stalks, leaves, and seeds) is manifold and has been used extensively by humans in different cultures in the past. Apart from the production of food or food supplements, hemp is also suitable for use as sails, ropes, textiles, and clothing, as well as a building material, so-called bioplastics or paper. Basically one can differentiate between industrial hemp, also known as (cannabis) Sativa L, which has no psychoactive effect of THC, and the so-called medical hemp (Cannabis Indica) with a higher THC content and possibly psychoactive, intoxicating effect.
Products made of industrial hemp as well as medical hemp can and are also used for medicinal or medical purposes. While industrial hemp is mainly cultivated in the field, occasionally also indoor, medical hemp is mainly cultivated indoor. The blossoms of both hemp types (useful and medical hemp) are also used as smoking goods, in this case, it is also called the “recreational market”.
Besides the more than 100 cannabinoids, the hemp plant contains more than 500 substances, such as terpenoids, flavonoids, and nitrogen compounds.

Cannabidiol, CBD for short, is one of over 100 cannabinoids in the hemp plant . In any case, it should be noted that the active substance CBD has no psychoactive effect . Some of the healing effects of CBD are well known, but some have not yet been fully researched. CBD contains hardly any THC, which is responsible for its psychoactive or intoxicating effect. In Europe, there are different limits, which are approved and vary between 0.2% (Germany), 0.3% (Austria), and 0.6% (Italy).
