Cannabis Metabolism & Edibles Guide

Infographic showing how THC from cannabis edibles is metabolized in the body, including digestion, liver conversion to 11-hydroxy-THC, bloodstream, and brain, with onset and duration timeline and factors like dose, tolerance, body fat, food intake, and genetics.

Cannabis Metabolism & Edibles Guide: How Your Body Processes THC

Understanding how your body metabolizes cannabis is key to safe, effective edible use. Unlike smoking or vaping, edibles pass through the digestive system and liver before reaching the bloodstream, creating unique effects in both intensity and duration.

This guide explains cannabis metabolism, how edibles are processed, factors affecting effects, and practical tips for safe dosing.


How Cannabis Is Metabolized in the Body

When you consume THC edibles:

  1. THC is digested in the stomach

  2. Absorbed in the intestines

  3. Travels to the liver

  4. Converted into 11-hydroxy-THC, a more potent form

  5. Enters the bloodstream and reaches the brain


Edible Cannabis Onset vs Smoking/Vaping

MethodOnset TimePeakDuration
Edibles30–120 min2–4 hrs6–8+ hrs
Smoking2–10 min30–60 min2–4 hrs
Vaping2–5 min30–60 min2–4 hrs

Key takeaway: Edibles take longer to start but often feel stronger and last longer due to liver metabolism.


Factors That Affect Cannabis Metabolism

1. Dosage

Higher doses take longer to metabolize and often produce stronger effects.

2. Tolerance

Regular users may process THC faster and feel shorter effects.

3. Body Weight & Fat

THC is lipophilic (stored in fat), affecting duration and intensity.

4. Food Intake

  • Empty stomach: faster, stronger effects

  • Full stomach: slower, milder effects

5. Enzymes & Genetics

Individual liver enzyme activity can affect how quickly THC converts to 11-hydroxy-THC.


THC & CBD Metabolism Differences

CompoundMetabolism PathwayEffect Duration
THCLiver → 11-hydroxy-THCLong-lasting, psychoactive
CBDLiver → inactive metabolitesNon-psychoactive, moderate duration

Edible Dosing & Safety Tips

Experience LevelSuggested Dose
Beginner2.5–5 mg THC
Occasional User5–10 mg THC
Experienced10–20 mg THC
High Tolerance20+ mg THC (use caution)

Tips:

  • Always wait 2 hours before taking more

  • Avoid mixing with alcohol

  • Keep in a safe environment

  • Track your personal response


Cannabis Metabolism FAQ

How long does it take for edibles to kick in?

30–120 minutes, depending on metabolism, stomach contents, and dose.

Why do edibles feel stronger than smoking?

The liver converts THC into 11-hydroxy-THC, which crosses the blood-brain barrier more efficiently.

How long do edible effects last?

6–8 hours on average, with residual effects up to 24 hours in some cases.

Can CBD affect THC metabolism?

Yes CBD can slow THC metabolism slightly, altering onset and intensity.

Does eating before an edible matter?

Yes a full stomach delays onset but smooths the experience; an empty stomach speeds onset but can feel stronger.


Final Thoughts

Understanding cannabis metabolism is essential for safe and enjoyable edible use. By knowing how your body processes THC and CBD, you can:

  • Predict onset and peak effects

  • Avoid overconsumption

  • Choose the right dose and timing

  • Maximize desired effects safely
