Methods of Ingestion
The primary methods of ingesting Sour Amnesia include inhalation (smoking/vaping), oral consumption (edibles/tinctures), sublingual administration, and topical application. Each method affects the absorption rate, bioavailability, and overall intensity of effects.
A. Inhalation (Smoking & Vaping)
Mechanism:
- THC and terpenes are rapidly absorbed through the alveoli in the lungs, entering the bloodstream within seconds to minutes.
- Directly interacts with CB1 receptors in the brain, leading to an almost immediate psychoactive effect.
- Bioavailability: 25–35% (higher compared to oral ingestion).
- Fastest onset but shorter duration of effects.
Onset & Duration:
| Factor | Smoking | Vaping |
|---|---|---|
| Onset | 1–5 min | 30 sec – 3 min |
| Peak Effects | 15–30 min | 10–20 min |
| Total Duration | 2–4 hours | 2–3 hours |
Comparison of Smoking vs. Vaping:
- Smoking (joints, pipes, bongs) burns plant material, which destroys some terpenes but provides a full-spectrum experience.
- Vaping (dry herb vaporizers) preserves terpenes due to controlled temperature settings, leading to a cleaner high with potentially more pronounced cerebral effects.
B. Oral Ingestion (Edibles & Tinctures)
Mechanism:
- THC is metabolized in the liver into 11-hydroxy-THC, a more potent psychoactive compound than delta-9-THC.
- Slower onset but longer and more intense effects due to sustained release.
- Bioavailability: 4–20% (due to first-pass metabolism).
Onset & Duration:
| Factor | Edibles (Gummies, Brownies) | Tinctures |
|---|---|---|
| Onset | 30–90 min | 15–45 min |
| Peak Effects | 2–3 hours | 1–2 hours |
| Total Duration | 6–8 hours | 4–6 hours |
Notes:
- Edibles provide a stronger body high, making them ideal for pain relief but less predictable in dosage.
- Tinctures, when taken sublingually, bypass first-pass metabolism and are absorbed directly into the bloodstream, leading to a faster onset.
C. Sublingual Administration (Tinctures & Sprays)
Mechanism:
- THC is absorbed through mucous membranes under the tongue, avoiding liver metabolism.
- Faster onset than edibles but shorter duration than smoking.
Onset & Duration:
| Factor | Sublingual |
|---|---|
| Onset | 15–45 min |
| Peak Effects | 45–90 min |
| Total Duration | 4–6 hours |
Advantages:
- Provides precise dosing compared to smoking or edibles.
- More bioavailable than edibles but less potent than inhalation.
D. Topical Application (Creams & Transdermal Patches)
Mechanism:
- Does not produce psychoactive effects unless formulated as a transdermal patch with THC permeability enhancers.
- Primarily interacts with CB2 receptors in the skin for localized pain relief and anti-inflammatory benefits.
Onset & Duration:
| Factor | Topicals | Transdermal Patches |
|---|---|---|
| Onset | 10–30 min | 30–60 min |
| Peak Effects | 1–2 hours | 2–4 hours |
| Total Duration | 2–4 hours | 8–12 hours |
Use Cases:
- Standard topicals: Used for arthritis, joint pain, and muscle inflammation.
- Transdermal patches: Allow slow THC absorption into the bloodstream, providing long-lasting relief.
