We’ve all been there: you eat a gummy, wait thirty minutes, feel nothing, and wonder if it’s working. Then, an hour later, it hits you all at once. But have you ever wondered why gummies take so long to kick in compared to vaping, or why a 10mg Delta-9 gummy feels so much more intense than 10mg of CBD?
The answer lies in a fascinating trip through your digestive system, a specialized "filter" in your liver, and a vast internal network called the Endocannabinoid System (ECS).
Step 1: The Digestive Scenic Route
Unlike smoking or vaping—where cannabinoids enter the bloodstream through the lungs almost instantly—gummies have to go through the digestive tract.
-
Stomach & Small Intestine: After you swallow a gummy, your stomach acids break it down. The cannabinoids are then absorbed through the walls of your small intestine.
-
The Fat Factor: Cannabinoids are "lipophilic" (fat-loving). If you eat a gummy on an empty stomach, absorption is often lower. However, taking it with a healthy fat (like avocado or peanut butter) creates "micelles"—tiny spheres that help the cannabinoids slip through your intestinal lining and into your blood more effectively.
Step 2: The Liver’s "First-Pass" Magic
This is where the magic (and the potency) happens. Once absorbed, the cannabinoids travel through the portal vein straight to the liver. This is called First-Pass Metabolism.
In the liver, enzymes (specifically the CYP450 family) go to work. For Delta-9 THC, the liver converts it into a metabolite called 11-Hydroxy-THC.
-
Why this matters: 11-Hydroxy-THC is significantly more potent and can cross the blood-brain barrier more easily than the original THC. This is why "edible highs" feel much heavier and last longer than the effects of smoking.
Step 3: Meeting the Endocannabinoid System (ECS)
Once the cannabinoids leave the liver and enter your general circulation, they seek out the Endocannabinoid System. Think of the ECS as your body’s "master regulator," responsible for keeping things like mood, pain, sleep, and appetite in balance (homeostasis).
The cannabinoids "talk" to two main types of receptors:
-
CB1 Receptors: Concentrated in the brain and central nervous system. These are the "locks" that THC fits into, triggering euphoria, relaxation, or the "munchies."
-
CB2 Receptors: Found mostly in your immune system and peripheral organs. CBD tends to interact here indirectly, helping to reduce inflammation and physical tension without the "high."
Why Different Cannabinoids "Hit" Differently
Even though they all go through the same digestive path, the way they lock into your ECS determines the experience:
| Cannabinoid | Interaction Style | Typical Experience |
| CBD | Indirectly influences receptors; boosts your own "bliss molecules" (Anandamide). | Calm, centered, non-intoxicating. |
| Delta-8 THC | Binds to CB1, but with a slightly different "grip" than Delta-9. | A smoother, clearer high; often reported as "Delta-9's chill cousin." |
| Delta-9 THC | Strong, direct bond with CB1; converts to 11-Hydroxy-THC. | Intense euphoria, deep relaxation, potent body high. |
| THCP | A much "longer" tail allows it to bind to CB1 up to 30x more effectively. | Extremely potent and long-lasting; for experienced users only. |
The Bottom Line
When you eat a gummy, you aren't just eating a candy; you're triggering a complex biological chain reaction. Because of the liver’s conversion process and the slow release from your digestive system, gummies offer a longer-lasting, more physical experience than almost any other method.
