Cannabis plays an important role in human history. It is an important raw material for clothing, paper, food, rope and so on. With the development of cotton processing industry and chemical fiber industry, cannabis production has gradually shrunk. In addition, cannabis was once banned because of its unique psychoactive substance, tetrahydrocannabinol. In recent years, many countries have developed non-toxic (low toxic) industrial cannabis, and people attach importance to the sustainable development of resources. The cannabis industry has begun to recover. Currently, Canadian, Australian, European Union countries, Russia and Asia allow the cultivation of industrial cannabis.
Cannabis seed oil contains essential fatty acids and natural active ingredients, which endow it with unique functional characteristics and meet the current demand for healthy diet. It can be used as a new type of functional oil resources for development and utilization. Canadian and European companies have developed cannabis seed oil products, including edible oils, human skin care products and so on.

At present, the research of cannabis seed oil is still in its infancy. China has abundant variety resources and vast consumer market. It should take the initiative in the research and product development of cannabis seed oil. It is suggested that research should be carried out in the following three aspects: the preparation technology and storage stability of cannabis seed oil; the active ingredients of cannabis seed oil. Research and nutritional function evaluation, application of cannabis seed oil in food and development of functional food.
