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.
Hemp seeds are high in nutritional value and contain 20 different varieties of amino acids and all nine of the essential amino acids (like flax). Some essential amino acids can't be naturally produced by the body and these seeds have the capacity to supplement them in the body. They contain high amounts of protein, which helps in strengthening the immune system, thereby, reducing the instances of diseases, besides helping in excreting toxins from the body. Studies in the recent past have shown that consuming hemp seeds whether raw or in oil form, has the capacity to aid in the healing process of diseases related to immune deficiency. There is no other food substance which contains such high quantities of essential fatty acids found in hemp seeds, higher than even flaxseed and other nut or seed oil as well as containing high amounts of vitamin E and trace minerals. It has a balanced ratio of omega 3 to 6 fats at around a three to one ratio. This won't help correct your omega balance if it's off, but it gives you the right balance to start with.
Hemp plants can be vulnerable to various pathogens, including bacteria, fungi, nematodes, viruses and other miscellaneous pathogens. Such diseases often lead to reduced fiber quality, stunted growth, and death of the plant. These diseases rarely affect the yield of a hemp field, so hemp production is not traditionally dependent on the use of pesticides.
Considering its popularity from long ago, when even our forefathers appreciated the value of hemp seeds, it seems unusual that the plant would have such a bad reputation today. Both George Washington and Thomas Jefferson grew hemp plants in their gardens. Hemp paper was even used for the Declaration of Independence, and Benjamin Franklin produced hemp paper at his mill. The environmental advantages and nutritional benefits of growing industrial hemp seem to many to be worth lifting its restrictions.

Hemp seeds, or hemp hearts, are the seeds of the hemp plant, Cannabis sativa. Technically a nut, these small, crunchy seeds are safe to consume and contain only traces of a psychotropic chemical, called THC, the primary psychoactive compound in cannabis which is known to cause euphoria. These seeds have a soft, creamy filling which has a mild, nutty flavor, and they are usually eaten raw.
