Absorption
Absorption is the process by which a substance enters the bloodstream or plant system. In cannabis, absorption determines how water, nutrients, or cannabinoids become usable by the body or plant.

What Absorption Means
Absorption refers to the movement of substances from an external source into a biological system where they can be used. In cannabis cultivation and consumption, absorption plays a central role in both plant health and user experience, though the process differs depending on context.
Absorption in Cannabis Plants
In cannabis plants, absorption occurs primarily at the roots. Water and dissolved nutrients move from the growing medium into the root system through specialized root cells and fine root hairs. Once absorbed, these materials are transported throughout the plant to support photosynthesis, growth, and flower development. Proper absorption depends on factors such as moisture levels, oxygen availability, root health, and pH balance. When absorption is impaired, plants may show deficiency symptoms even when nutrients are present.
Absorption in Cannabis Consumption
In cannabis consumption, absorption refers to how cannabinoids enter the human bloodstream after use. With inhalation, cannabinoids are absorbed through the lungs and enter circulation quickly. With oral or edible products, absorption occurs through the digestive system and liver, resulting in slower onset and longer-lasting effects. The efficiency of this process influences potency, timing, and overall experience.
Absorption and Bioavailability
Absorption is closely tied to the concept of bioavailability, which describes how much of a substance actually reaches circulation in an active form. Not all absorbed material produces effects, and absorption rates vary based on method, formulation, and individual biology. This is why the same dose can feel different depending on how cannabis is consumed.
Why Absorption Matters
Understanding absorption is essential in both cultivation and use. For growers, optimizing absorption supports healthy plants and consistent yields. For users, understanding absorption helps with dosing decisions, onset expectations, and safer cannabis experiences across different consumption methods.
