Hempseed's amino acid profile is comparable to other sources of protein such as meat, milk, eggs and soy. Protein digestibility-corrected amino acid scores (PDCAAS), which attempt to measure the degree to which a food for humans is a "complete protein", were 0.49–0.53 for whole hemp seed, 0.46–0.51 for hempseed meal, and 0.63–0.66 for hulled hempseed.
Hemp is completely different from marijuana in its function, cultivation and application. But these differences didn’t stop our political leaders from getting confused and accidentally grouping all Cannabis species as a Schedule I Drug and banning it in 1970 under the Controlled Substances Act. Even after 45 years, the government still seems to have some confusion in distinguishing the two plants. Although legislation is being made, progress has been slow.In its application, hemp and marijuana serve completely different purposes. Marijuana, as it is widely known, is used for medicinal or recreational purposes. Hemp is used in variety of other applications that marijuana couldn’t possibly be used in. These include healthy dietary supplements, skin products, clothing, and accessories. Overall, hemp is known to have over 25,000 possible applications.
Industrial hemp is a very hardy plant, able to be be grown in areas where other crops will fail. It can withstand periods of drought, heat and frost and also be cultivated without pesticides or other chemicals in many instances – however, it can be subject to attack by insect pests. It doesn’t have huge water requirements or a great need for ongoing care. The plant grows quite quickly, achieving heights of 4 metres in four months.
In this review, the effects of cannabinoids in the regulation of the following endocrine systems are discussed: the hypothalamic-pituitary-gonadal axis and hypothalamic-pituitary-adrenal cortex axis. Cannabis users have reduced levels of gonadotropins, reduced prolactin and growth hormone. Cannabis affects corticotropin-releasing hormone-, thyrotropin-releasing hormone-, vasopressin-, and oxytocin-expressing neurons. Therefore, our findings reveal a mechanism of rapid glucocorticoid feedback inhibition of hypothalamic hormone secretion via endocannabinoid release in the paraventricular nucleus of the hypothalamus and provide a link between the actions of glucocorticoids and cannabinoids in the hypothalamus that regulate stress and energy homeostasis. Glucocorticoid negative feedback in the brain controls stress, feeding, and neural-immune interactions by regulating the hypothalamic-pituitary-adrenal axis. Cannabis increases dopamine which decreases prolactin. Cannabis decreases oxytocin, thyroid hormone and growth hormone, and disrupts the hypothalamic-pituitary-adrenal axis. Cannabinoids suppress fertility via reducing hypothalamic gonadotropin- releasing hormone output. γ-Aminobutyric acid (GABA)(A) receptor (GABA(A)-R)-mediated transmission is a major input to gonadotropin releasing hormone cells that can be excitatory. Cannabinoids act via inhibiting GABAergic input. Cannabis disregulates the hypothalamic-pituitary-adrenal axis circadian rhythm. Cannabis decreases serum concentrations of pituitary gonadotropins. Cannabis raises cortisol and ACTH which increases cortisol which uses up progesterone reducing testosterone and estrogen. Cannabis lowers testosterone in men by inhibiting testosterone secretion and impairs fertility in males through alteration in the testicular endocannabinoid system. Cannabis suppresses copulatory behavior even when testosterone levels are maintained. It decreases sperm concentration, causes defective sperm function or alteration of sperm morphology. Endocannabinoids control male reproduction acting at central and local level via cannabinoid receptors. The cannabinoid receptor CB1 has been characterized in the testis, in somatic and germ cells of mammalian and non-mammalian animal models, and its activity related to Leydig cell differentiation, steroidogenesis, spermiogenesis, sperm quality, and maturation. Testicular degeneration and necrosis is induced by chronic administration of cannabis. In both ovulating and menopausal women, cannabis can alter pituitary gonadotropin release and alter metabolism or target tissue response to gonadal steroids, leading to reduced estrogen and progesterone production and anovulatory menstrual cycles. Cannabis presents abnormal longer ovulatory cycle lengths in females. Cannabis suppresses luteinizing hormone when sex hormones are initially high, but, chronic cannabis lowers progesterone and testosterone in men, and lowers estrogen and progesterone in women, so luteinizing hormone significantly increases which raises night time core temperature for disrupted sleep. Cannabis increases hypothalamic nitric oxide which inhibits oxytocin. Cannabis is detrimental for lactating moms. Cannabis decreases maternal care, decreases aggressive instinctual behaviors for protection of young, suppresses maternal anxiolysis, decreases plasma oxytocin levels and milk consumption and decreases activation of oxytocinergic neurons in hypothalamic nuclei. Changes in the behavioral responses of lactating mothers treated with cannabis can be related to disruption in the neuroendocrine control of oxytocin secretion. Cannabis causes impairment of glucocorticoid feedback which either enhances or decreases performance on various tasks. Cannibis can cause a decrease in thyroid which negatively affects cerebellar development and motor performance involved in adult brain function. It induces consistent behavioral changes in adults, leading to severe anxiety and morphological changes in the hippocampus, however, it shows improvements for schizophrenia: improvement in cognitive function and reduction of antipsychotic-side. Cannabis and Δ(9) -THC are anticonvulsant in most animal models but can be proconvulsant in some healthy animals. The simultaneous rapid stimulation of nitric oxide and endocannabinoid synthesis by glucocorticoids has important implications for the impact of stress on the brain as well as on neural-immune interactions in the hypothalamus. Cannabis has implications for psychosis. There are blunted psychotomimetic and amnestic effects with cannabis. Lithium increases oxytocin and helps in cannabis withdrawal, and pregnenolone/progesterone help in cannabis withdrawal as estrogen generally increases and progesterone decreases sensitivity to marijuana.
Hemp can be used as a "mop crop" to clear impurities out of wastewater, such as sewage effluent, excessive phosphorus from chicken litter, or other unwanted substances or chemicals. Additionally, hemp is being used to clean contaminants at the Chernobyl nuclear disaster site, by way of a process which is known as phytoremediation—the process of clearing radioisotopes and a variety of other toxins from the soil, water, and air.
Buying online is less reliable still because there’s no regulation or standardization. What you see on the label may not be what you are getting. A 2017 study in JAMA found that of the 84 CBD products researchers bought online, 43% had more CBD than indicated, while 26% had less, and some had unexpected THC. “There’s a 75% chance of getting a product where the CBD is mislabeled,” says Marcu, one of the study’s coauthors.

In other words, smoking hemp cannot create a 'high.' ... The dense growth of hemp eliminates other weeds.... The best growing technique for hemp, planting 300 to 500 plants per square meter, also helps authorities easily tell the hemp from marijuana, which is a plant that is less densely cultivated. (Roulac 1997; 149).
Although cannabis can be used to make marijuana, CBD itself is non-psychoactive—meaning that it doesn’t get you high the way smoking or eating cannabis-related products containing THC (the plant's psychoactive compound) can. Still, there’s a lot doctors don’t know about CBD and its effects on the body, and a lot consumers should understand before trying it.
