The Pharmacokinetics of Edible THC
When cannabis is consumed as an edible, delta-9 THC is metabolized differently compared to inhaled cannabis. This process involves the edible passing through the digestive system and liver before entering the bloodstream. In the liver, delta-9 THC is converted into 11-hydroxy-THC, a more potent and longer-lasting compound. This contributes to the delayed onset, extended effects, and increased potency of edibles. Unlike smoking or vaping where THC enters the bloodstream directly via the lungs, edibles' effects are not immediate.
Why High Doses are Uniquely Potent
A high dose edible can be very potent, significantly exceeding recommended starting amounts. For those with low tolerance, it can lead to intense and potentially overwhelming effects. The conversion of THC to 11-hydroxy-THC in the liver makes a high dose edible considerably more powerful and longer-lasting than an equivalent smoked dose. A high dose can produce effects for 12 hours or more, with lingering effects for up to 24 hours.
Factors Influencing How Long Edibles Stay in Your System
The duration THC remains detectable varies based on several factors, including frequency of use, individual metabolism, body fat percentage, stomach contents, hydration and diet, and the potency and quantity consumed.
Edibles vs. Smoked Cannabis: A Comparison
The experience of edibles differs significantly from smoking:
| Characteristic | Edibles | Smoked/Vaped Cannabis |
|---|---|---|
| Onset of Effects | 30 minutes to 2 hours or more | Almost immediate, within 1 to 10 minutes |
| Peak of Effects | Typically 2 to 4 hours | Within 30 to 60 minutes |
| Duration of High | 4 to 12 hours, potentially longer with high doses | 1 to 3 hours |
| Potency | Often more intense due to 11-hydroxy-THC | Perceived as less intense overall |
| Detection Window | Can be longer in urine, up to 30+ days for heavy users | Can be detected for shorter periods in urine for occasional users |
Detection Windows for High-Dose Edibles
For drug testing, a high dose edible will likely result in longer detection times depending on the test type and usage frequency. Urine tests may detect a single high dose for 3-7 days, or 30 days or more for regular users. Blood tests typically detect recent use within 3-4 days, while saliva tests have a window of 1-3 days for edibles. Hair follicle tests can detect long-term use for up to 90 days or more.
Conclusion
The duration a high dose edible remains in your system is highly variable due to individual factors. A high dose can cause intense effects lasting 12 hours or longer, with residual effects up to 24 hours. Detection windows vary by test type and usage frequency, from days to over 90 days. Due to the potency of high-dose edibles, caution is advised. Always "start low and go slow." For more on THC metabolism, consult resources like the National Institutes of Health.

Edibles and Metabolism: How THC is Processed
Eating an edible leads to THC entering the bloodstream via the intestines and being converted in the liver to the more potent 11-hydroxy-THC, resulting in slower onset and longer effects.
Detecting High-Dose Edibles in Drug Tests
A high dose, particularly for regular users, can lead to detectable THC metabolites for weeks or months depending on the test type (urine, hair).
Understanding High-Dose Edible Effects
A high dose edible can cause an intense and prolonged high lasting 12 hours or more.
Factors Affecting Your Edible Experience
Metabolism, body fat, frequency of use, and stomach contents all influence an edible's onset, duration, and intensity.
Responsible Consumption with High Doses
Due to the high risk of adverse effects with high dose edibles, especially for inexperienced users, it is crucial to start with a much smaller dose.
