hemp seed is a rich source of Omega-3 and Omega-6 essential fatty acids (EFAs), providing both SDA and GLA, highly-digestible protein, and naturally-occurring vitamins and minerals, such as vitamin E and iron. An excellent source of dietary fiber, hemp seed is also a complete protein—meaning it contains all ten essential amino acids, with no enzyme inhibitors, making it more digestible by the human body.
Hemp has been used for making several products that span the history of the United States. Its association with marijuana downplays the significance it has had in the history of commerce. If children are going to learn about factual history they need to know all sides of an argument, not just the one normally provided in books and school.
Hemp is best known as a product of the marijuana plant. All though industrial hemp is, typically, produced from genetically marijuana plants most people don't know this and still think hemp production is equivalent to marijuana production. Hence, in the minds of some a celebration of hemp, a International Hemp Week, may be seen as a "stoner holiday", a celebration of marijuana production and by extension drug use.
I think that if you're interested in hemp, then you should feel free to celebrate. If you don't approve of hemp products or have no interest in the plant then there's no reason for you to recognize international hemp week. Hemp week isn't a holiday for everyone, but for those who feel it cause to celebrate there's no reason they shouldn't.
