If a yearning for fudge brownies or gummy snakes has ever blindsided you, you’ve seemingly skilled the facility of hormones. Along with driving wishes for sure meals, the physique’s many hormones additionally assist hearth up the libido, regulate temper, sleep, and even physique temperature. 

Many know first-hand how hashish exerts delicate—or not-so-subtle—results over our temper, sleep, and urge for food, so it’s clear the plant interacts with our hormones in a roundabout way. However how?

The endocannabinoid and endocrine techniques

Hormones are useful chemical messengers secreted by the endocrine system, a community of glands and organs that launch hormones into the physique. The major endocrine glands embody the hypothalamus, pituitary, pancreas, pineal, thyroid, parathyroid, adrenal, ovaries, and testes.

“There are roughly 50 completely different hormones within the physique,” mentioned Dr. Patricia Frye, MD, a board director for the Society of Cannabis Clinicians. “Some hormones are launched to stimulate glands to launch hormones, and different hormones act on track organs to modulate numerous metabolic capabilities.”

The endocannabinoid system is one other important regulatory power within the physique. Sleep, temper, metabolism, urge for food, bone development, fertility—the endocannabinoid system options in all these processes. Scientists imagine the primary perform of the endocannabinoid system is to deliver these capabilities into homeostasis, or stability. 

“General, hashish interacts with the endocannabinoid system, a neuro-modulating system that maintains stability or homeostasis within the physique,” mentioned Frye. “Provided that, it will stand to motive that the system oversees virtually each neurotransmitter and hormonal system. We now have studied among the mechanisms of this oversight, significantly in preclinical, animal research, however there’s nonetheless lots that we don’t absolutely perceive as to how these findings translate into people.” 

There’s proof, nonetheless, that the endocannabinoid system is concerned in appetite, sexual function, and stress.

What is the endocannabinoid system and what is its role?

Most of us are accustomed to the heavy-duty pizza cravings that may accompany a joint. Hashish is already identified to elevate appetite and intensify pleasure we expertise when consuming. 

Ghrelin

In a 2020 study printed in Nature, researchers found that ghrelin hormone ranges have been greater after consuming hashish orally relatively than smoking or vaporizing hashish. Ghrelin is affectionately referred to as the “starvation hormone” as a result of it ignites appetite and adjusts food intake

Rising evidence additionally suggests there’s a collaborative interplay between the endocannabinoid system and ghrelin. Each drive feeding, and specialists imagine the 2 work synergistically to encourage starvation and consuming. Endocannabinoid and ghrelin receptors are additionally equally distributed in areas of the mind related to feeding, and in organs concerned in metabolism.

Leptin

Hashish additionally influences the physique’s leptin hormone ranges. “Leptin is secreted by the fats cells and sends alerts to the hypothalamus regulating meals consumption and vitality expenditure, serving to one keep their regular physique weight or set level,” mentioned Frye. 

Analysis has proven that hashish people who smoke have lower leptin levels than non-smokers. This discovering might clarify why hashish people who smoke are inclined to have lower body fat percentages and obesity rates.

“The extra physique fats you may have, the extra leptin circulating to keep up that fats mass by rising urge for food and lowering metabolic charge,” mentioned Frye. “Hashish customers additionally are inclined to have decrease BMIs and waist circumferences than non-users.”

Insulin and glucose

Hashish additionally seems to affect insulin concentrations, the hormone chargeable for regulating glucose by way of the physique. When the proper focus of insulin is circulating within the blood, glucose is transported into cells to change into gasoline to keep up vitality ranges.

Within the case of diabetics, for instance, inadequate insulin ranges means glucose just isn’t directed into the physique’s cells however stays circulating within the blood, inflicting hyperglycemia.

In a 2020 study, members given a placebo brownie skilled a spike in blood-insulin concentrations. That’s pretty predictable—many people know the frenzy, then the unavoidable freefall, that comes with a sugar hit. 

Nevertheless, when members got a brownie infused with THC, the insulin spike was blunted. No matter whether or not hashish was consumed orally, smoked or vaporized, insulin ranges remained significantly decrease than the controls. 

Frye additionally factors out that CBD has been linked to improved glucose metabolism. “Human trials are missing however in my scientific expertise, it’s not unusual to see sufferers with Sort 2 diabetes whose glucose-lowering treatment doses come down after beginning CBD. This may be a perform of CBD’s anti-inflammatory or stress-relieving results, or a direct impact on glucose metabolism and/or insulin sensitivity,” she mentioned.

Let’s speak about intercourse, child… and hashish

What concerning the affect of hashish on different appetites? Hormones are a important consider intercourse drive and fertility. Common hashish shoppers typically debate whether or not weed boosts or stifles intercourse drive. 

Cannabinoid receptors have been present in each female and male hormones and within the endocrine glands concerned in copy and fertility, together with the hypothalamus, pituitary gland, ovaries, and testes

“Hashish stimulates the discharge of oxytocin, which can also be referred to as the ‘hugging hormone.’ It’s chargeable for reproductive capabilities like uterine contractions throughout labor and breastfeeding,” defined Frye. “Oxytocin can also be chargeable for the satisfaction folks expertise from social interplay, and promotes emotional bonding.” 

Frye factors on the market’s conflicting proof concerning the results of hashish on male fertility. “A 2015 study in people confirmed a 29% lower in sperm rely, as have quite a few preclinical research,” she mentioned. “Nevertheless, a 2019 study of males evaluated for infertility discovered that males who self-reported smoking hashish recurrently had the next sperm rely than males who had by no means smoked hashish.” 

Brief-term hashish use might increase libido, however continual use may additionally trigger erectile dysfunction. “Whereas low to reasonable doses of THC can promote bonding, heighten arousal, and stimulate an erection, an excessive amount of THC may cause anxiousness or impede ejaculation which can negatively impression the sexual encounter,” mentioned Frye.

“I don’t suggest hashish use for girls actively attempting to conceive and/or maintain a being pregnant, besides when the good thing about hashish remedy far outweighs the danger of impaired fertility,” suggested Frye.

Alternatively, hashish seems to spice up the feminine intercourse drive. In a study of ladies who reported utilizing marijuana earlier than intercourse, 68.5% divulged that their total sexual expertise was extra pleasurable, 60.6% reported a rise in intercourse drive, and 52.8% shared that they’d  skilled a rise in satisfying orgasms. 

Cease stressing: weed and cortisol ranges

Cortisol is the physique’s major stress hormone. As soon as cortisol kicks in, non-essential bodily capabilities are curbed so the physique can enter combat or flight mode. Whereas THC in hashish sometimes elevates cortisol levels, particular person experiences of results will differ based mostly on frequency of use.

For infrequent shoppers, a rise in cortisol can improve blood strain and provoke anxiousness. Lengthy-term shoppers can change into habituated to this common cortisol spike, dulling a response to acute stress

Cortisol isn’t simply chargeable for stimulating stress, nonetheless. A morning dose of cortisol can also be important for getting off the bed within the morning—cortisol peaks within the morning and slowly declines all through the day.

That mentioned, Frye additionally acknowledged that hashish has been acknowledged to enhance numerous signs related to endocannabinoid imbalance, leading to enhanced well being and well-being. “These advantages may additionally be a perform of hormonal changes that might ordinarily be modulated by satisfactory ranges of circulating endocannabinoids,” she mentioned.
