CBD is generally extracted from commercial hemp plants, which must be grown with care in the EU. CBD pollinate, as CBD hash is also called, is extracted from flowers of a female cannabis plant.
Depending in the culture, there are many different ways of producing pollinates. In most cases, CBD hash is extracted by classical sieving, and further processing is then carried out as with classical hashish.
However, the THC content of all products is always below 0.2 %, the limit permitted in the EU.
