With cannabis gaining mainstream acceptance and legalization in many areas, interest in its effects on the body has also surged. From smoking cannabis to consuming edibles, cannabis can have diverse impacts on different body systems, affecting the nervous, respiratory, and digestive systems. Beyond these immediate effects, cannabis also has implications for satiety, metabolism, and even specific dietary protocols like ketogenic, paleo, and carnivore diets. This post dives into how cannabis interacts with the body’s major systems and explores its potential for health optimization.
How Cannabis Affects the Nervous System
Cannabis primarily affects the central and peripheral nervous systems, interacting with the body’s endocannabinoid system (ECS), a network of receptors that helps regulate mood, memory, appetite, and pain sensation.
-
Impact on Neurotransmitters and Brain Activity
- The active compounds in cannabis, notably THC and CBD, bind to receptors in the brain, influencing the release of neurotransmitters like dopamine, serotonin, and GABA.
- Euphoria and Relaxation: THC, the psychoactive compound, stimulates dopamine release, leading to the classic “high” feeling.
- CBD’s Role: While THC is psychoactive, CBD has calming effects without euphoria. It is often used to alleviate anxiety and manage pain without the high associated with THC.
-
Cannabis and Pain Perception
- The endocannabinoid system plays a crucial role in pain modulation. Studies suggest that both THC and CBD can help alleviate chronic pain conditions by interacting with pain-signaling pathways, making cannabis an option for some individuals seeking pain relief.
How Cannabis Affects the Respiratory System
While smoking is a common method for consuming cannabis, it can have serious consequences for the respiratory system, similar to those associated with smoking tobacco.
-
Impact of Smoke Inhalation
- Cannabis smoke contains harmful toxins and tar that can lead to respiratory issues like bronchitis, coughing, and wheezing.
- Lung Inflammation: Smoking cannabis can cause inflammation in the lungs, impairing respiratory function over time.
-
Alternatives to Smoking: Edibles and Vaporizers
- For individuals concerned about respiratory health, edibles, tinctures, or vaporizing offer alternatives that bypass direct lung involvement.
- Edibles: When consumed as edibles, THC is metabolized by the liver, leading to a delayed but prolonged effect, which has different implications for health compared to inhalation.
Cannabis and the Digestive System
When consumed as edibles, Cannabis affects the digestive system and can influence appetite, satiety, and even metabolism.
-
Stimulating Appetite
- Often referred to as the “munchies,” cannabis is known for increasing appetite, primarily due to THC’s effect on the brain’s hypothalamus. This can be beneficial for individuals with reduced appetites due to medical conditions.
-
Impact on Satiety and Digestion
- Satiety Hormones: Research suggests that THC may disrupt hormones related to satiety, such as leptin and ghrelin, often leading to an increased desire to consume high-calorie foods.
- Digestive Health: Cannabinoids can reduce inflammation in the gut and are being explored for conditions like Crohn’s disease and irritable bowel syndrome (IBS), where inflammation plays a role.
Cannabis and Metabolism: Effects on Weight and Energy Balance
The interaction between cannabis and metabolism is complex, with some studies indicating that cannabis users tend to have lower body mass indexes (BMIs) despite increased caloric intake.
-
Effects on Metabolism
- Cannabis may increase basal metabolic rate (BMR) and impact insulin sensitivity. Some studies suggest a connection between cannabis use and improved blood sugar control, though more research is needed.
-
Impact on Fat Storage
- Animal studies indicate that cannabinoids may alter fat storage, potentially affecting “browning” white adipose tissue, which is metabolically active and may influence weight loss.
-
Cannabis and Specific Diets
- Ketogenic Diet: Since THC may increase hunger and cravings for carbohydrate-rich foods, it could potentially disrupt a strict ketogenic protocol.
- Paleo and Carnivore Diets: While cannabis does not contain non-permitted ingredients in these diets, increased cravings for high-calorie foods could conflict with the dietary goals of paleo and carnivore approaches.
Cannabis and Satiety
Cannabis’s effect on hunger and satiety is well-documented. Its influence on appetite is mainly due to how THC interacts with the hypothalamus.
-
Increased Appetite (The “Munchies”)
- THC stimulates the hypothalamus, which may override normal satiety signals. Which leads to increased food consumption and cravings, especially for sweet or salty foods.
-
Impact on Satiety Hormones
- Cannabis appears to affect ghrelin, a hormone that stimulates hunger, potentially prolonging the desire to eat. However, cannabinoids also impact leptin, the hormone responsible for signaling fullness, though the effects vary by individual.
Health Optimization and Cannabis: What the Research Says
Research on cannabis’s impact on health optimization is still in its early stages. Most studies focus on symptom relief rather than long-term health benefits. Here’s a look at some areas where cannabis shows promise:
-
Chronic Pain and Inflammation
- Cannabis’s anti-inflammatory and analgesic properties make it a valuable tool for chronic pain management, and some biohackers use it for recovery, muscle relaxation, and stress reduction.
-
Mental Health and Stress Reduction
- CBD, in particular, has been studied for its potential to reduce anxiety, improve sleep, and help manage stress. Cannabis could be a valuable component for those looking to optimize mental health, though it should be approached cautiously due to potential dependency.
-
Metabolic Health and Blood Sugar Control
- While limited, some research suggests that cannabis users have better insulin sensitivity and a lower likelihood of developing Type 2 diabetes. These effects, however, vary based on individual usage patterns and require further exploration.
Are There Counter Effects with Ketogenic, Paleo, or Carnivore Diets?
-
Ketogenic Diet
- Cannabis’s effect on hunger can conflict with ketogenic goals, as cravings for carbs may lead users to consume more carbohydrates, potentially disrupting ketosis.
- Some biohackers use CBD, which doesn’t trigger hunger, as a more keto-friendly option.
-
Paleo and Carnivore Diets
- While these diets focus on whole, unprocessed foods, cannabis use, especially edibles containing sugars or processed fats, may lead to dietary conflicts. Consuming pure, natural cannabis products may be more compatible with these nutritional philosophies.
-
Practical Tips for Integrating Cannabis with Low-Carb Diets
- Opt for low-sugar edibles and avoid products with added ingredients that could interfere with dietary goals.
- Track food intake after cannabis use to stay on target with macronutrient goals.
Final Thoughts on Cannabis and Health Optimization
Cannabis has potential benefits across multiple bodily systems. Its effects vary widely based on factors like dosage, method of consumption, and individual physiology. For those interested in using cannabis as part of a health optimization strategy, it’s essential to consult with a healthcare provider, consider individual goals, and approach usage mindfully.
