Once open, put the package or its contents in an airtight container and refrigerate or freeze it to extend the shelf life. Once opened, you can expect a bag of hemp seeds to last for about a year in the refrigerator or freezer. If you keep a package in your pantry, however, that shelf life will be more like 3 to 4 months. If you give your bag of seeds a sniff and they smell rancid, toss them.

Hemp paper are paper varieties consisting exclusively or to a large extent from pulp obtained from fibers of industrial hemp. The products are mainly specialty papers such as cigarette paper,[41] banknotes and technical filter papers.[42] Compared to wood pulp, hemp pulp offers a four to five times longer fibre, a significantly lower lignin fraction as well as a higher tear resistance and tensile strength. However, production costs are about four times higher than for paper from wood,[43] so hemp paper could not be used for mass applications as printing, writing and packaging paper.
The process to legalize hemp cultivation began in 2009, when Oregon began approving licenses for industrial hemp.[97] Then, in 2013, after the legalization of marijuana, several farmers in Colorado planted and harvested several acres of hemp, bringing in the first hemp crop in the United States in over half a century.[98] After that, the federal government created a Hemp Farming Pilot Program as a part of the Agricultural Act of 2014.[99] This program allowed institutions of higher education and state agricultural departments to begin growing hemp without the consent of the Drug Enforcement Agency (DEA). Hemp production in Kentucky, formerly the United States' leading producer, resumed in 2014.[100] Hemp production in North Carolina resumed in 2017,[101] and in Washington State the same year.[102] By the end of 2017, at least 34 U.S. states had industrial hemp programs. In 2018, New York began taking strides in industrial hemp production, along with hemp research pilot programs at Cornell University, Binghamton University and SUNY Morrisville.[103]
In the Australian states of Tasmania, Victoria, Queensland, Western Australia, New South Wales, and most recently, South Australia, the state governments have issued licences to grow hemp for industrial use. The first to initiate modern research into the potential of cannabis was the state of Tasmania, which pioneered the licensing of hemp during the early 1990s. The state of Victoria was an early adopter in 1998, and has reissued the regulation in 2008.[77]

The world-leading producer of hemp is China, which produces more than 70% of the world output. France ranks second with about a quarter of the world production. Smaller production occurs in the rest of Europe, Chile, and North Korea. Over 30 countries produce industrial hemp, including Australia, Austria, Canada, Chile, China, Denmark, Egypt, Finland, Germany, Greece,[70] Hungary, India, Italy, Japan, Korea, Netherlands, New Zealand, Poland, Portugal, Romania, Russia, Slovenia, Spain, Sweden, Switzerland, Thailand, Turkey, the United Kingdom and Ukraine.[71][72]
Jews living in Palestine in the 2nd century were familiar with the cultivation of hemp, as witnessed by a reference to it in the Mishna (Kil'ayim 2:5) as a variety of plant, along with Arum, that sometimes takes as many as three years to grow from a seedling. In late medieval Germany and Italy, hemp was employed in cooked dishes, as filling in pies and tortes, or boiled in a soup.[114] Hemp in later Europe was mainly cultivated for its fibers, and was used for ropes on many ships, including those of Christopher Columbus. The use of hemp as a cloth was centered largely in the countryside, with higher quality textiles being available in the towns.
Queensland has allowed industrial production under licence since 2002,[78] where the issuance is controlled under the Drugs Misuse Act 1986.[79] Western Australia enabled the cultivation, harvest and processing of hemp under its Industrial Hemp Act 2004[80], New South Wales now issues licences[81] under a law, the Hemp Industry Regulations Act 2008 (No 58), that came into effect as of 6 November 2008.[82] Most recently, South Australia legalized industrial hemp under South Australia’s Industrial Hemp Act 2017, which commenced on 12 November 2017.[83]
As of December 2018, Hemp is federally legal to grow again in the United States. The government passed the Hemp Farming Act of 2018, part of the 2018 Farm Bill[95] signed by President Donald Trump on 20 December 2018.[95] This bill changed hemp from a controlled substance to an agricultural commodity, legalizing hemp federally, which made it easier for farmers to get production licenses, get loans to grow hemp, and allowed them to get federal crop insurance.[95] Some states still consider it illegal to grow hemp, but 41 states have begun the process to make hemp legal to grow at the state level, as of 2019.[96]
There are many long-term health benefits that can be experienced. Hemp Seed is one of the best balanced sources of Omega 3 and Omega 6 essential fatty acids. Hemp Seed contains only small amounts of saturated and mono-unsaturated fats which can be easily converted to energy. Hemp Seed is also an unsurpassed source of the whole spectrum of required proteins, it promotes vigorous cellular development with diverse health benefits:

Hemp plants grow brown popcorn kernel-sized hard seeds. Inside these hard seeds lie soft, white or light green inner kernels that are packed with essential amino acids, protein, and omega-3 fatty acids. You can't really derive a lot of nutritional value from the unhulled seeds, so when you see a bag at the store labeled "hemp seeds," what you're actually buying is those soft inner kernels, also known as hemp hearts. Hemp hearts can be pressed to make hemp seed oil, leaving behind a byproduct that can be turned into hemp protein powder. You can find all of these hemp products at health food stores, or a well-stocked grocery store like Whole Foods.
There are no known allergic reactions to hemp seed, but the contact that the seeds may have had with THC-covered plant parts could result in small residues of THC on the seeds. This means that you could possibly experience the feeling of being “high” or under the effect of the psychotropic chemical. This effect of hemp seed is quite rare and isn’t harmful, but it can be an uncomfortable feeling if not anticipated.

It is sometimes supposed that an excerpt from Washington's diary, which reads "Began to seperate [sic] the Male from the Female hemp at Do.&—rather too late" is evidence that he was trying to grow female plants for the THC found in the flowers. However, the editorial remark accompanying the diary states that "This may arise from their [the male] being coarser, and the stalks larger"[120] In subsequent days, he describes soaking the hemp[121] (to make the fibers usable) and harvesting the seeds,[122] suggesting that he was growing hemp for industrial purposes, not recreational.
Industrial help has many uses, from paper and textiles to plastic and fuel. In fact, it can even be used in place of traditional paper made from trees, as hemp paper can be recycled more times than that made from wood. Hemp also yields nearly four times as much as trees. Plastic produced from hemp is also biodegradable, making it better for the environment. Hemp seeds can be used in a variety of food products as well.
Millennia of selective breeding have resulted in varieties that display a wide range of traits; e.g. suited for a particular environments/latitudes, producing different ratios and compositions of terpenoids and cannabinoids (CBD, THC, CBG, CBC, CBN...etc.), fibre quality, oil/seed yield, etc. Hemp grown for fiber is planted closely, resulting in tall, slender plants with long fibers.[citation needed]
Hemp seeds are rather oily and high in fat. One tablespoon contains 3 g to 4 g of fat. The majority of this is polyunsaturated fat --- the good kind of fat --- and according to Blue Shield of California, shelled hemp seeds contain both omega-3 and omega-6 fatty acids. However, all this fat can come at a price, and you may experience mild diarrhea when adding shelled hemp seeds to your diet. If your digestive system is sensitive to change, start with small amounts of hemp seed --- say, a teaspoon a day --- and slowly work your way up to the recommended serving of 2 tbsp.

Hemp seed has a wide range of effects on heart health, including the proper balance of cholesterol or fatty acids in the body. Most specialists recommended a specific balance of 3:1 or 4:1 omega-6 fatty acid to omega-3 fatty acid. According to Dr. Delfin Rodriguez Leyva’s, ( Department of Physiology, University of Manitoba and Institute of Cardiovascular Sciences, St Boniface Hospital Research Centre, Canada) report in the Nutrition and Metabolism Journal, this seed is one of the only plant substances in the world where this is the normal balance already. The proper balance of saturated fats in the body is essential to the normal functioning of the body, and the prevention of various conditions, including atherosclerosis, heart attacks, and strokes. Furthermore, since this seed has a high content of fiber, heart health is further boosted because fiber scrapes off excess cholesterol from the artery walls that also lead to heart conditions, and takes them to the excretory system where they can be processed and eliminated.
