Methods, Onset, and Duration of Effects
The pharmacokinetics and pharmacodynamics of Chem D.O.G. depend heavily on the route of administration, which influences bioavailability, onset time, peak effects, and duration. This section provides a comprehensive scientific breakdown of different ingestion methods, including inhalation, oral consumption, and sublingual administration.
1. Methods of Ingestion
Cannabis compounds in Chem D.O.G. (primarily THC, CBD, and terpenes) interact with CB1 and CB2 receptors in the endocannabinoid system (ECS). The route of administration significantly impacts how cannabinoids are absorbed, metabolized, and exert their effects.
1.1 Inhalation (Smoking and Vaporization)
Mechanism:
- Inhaled cannabis is absorbed via pulmonary alveoli in the lungs.
- THC and other cannabinoids enter the bloodstream directly, bypassing first-pass metabolism in the liver.
- Onset is rapid due to high bioavailability and direct passage into the systemic circulation.
| Factor | Smoking | Vaporization |
|---|---|---|
| Onset Time | 2 – 5 minutes | 1 – 3 minutes |
| Peak Effects | 30 – 60 minutes | 20 – 40 minutes |
| Duration | 2 – 4 hours | 1.5 – 3.5 hours |
| Bioavailability | ~30% | ~50-80% |
| Health Risks | Combustion byproducts | Reduced lung irritation |
Scientific Considerations:
- Vaporization heats cannabinoids to 200-230°C, preventing combustion byproducts such as benzene, tar, and carbon monoxide, making it a more secure option than smoking.
- Studies show vaporization preserves up to 95% of cannabinoids, whereas smoking destroys a significant percentage due to combustion.
1.2 Oral Ingestion (Edibles, Capsules, and Beverages)
Mechanism:
- Cannabinoids pass through the gastrointestinal tract, where they are absorbed into the bloodstream.
- In the liver, THC is metabolized into 11-hydroxy-THC, a more potent, long-lasting metabolite.
- This metabolic conversion leads to stronger psychoactive effects compared to inhalation.
| Factor | Edibles/Capsules |
|---|---|
| Onset Time | 30 – 90 minutes |
| Peak Effects | 2 – 4 hours |
| Duration | 4 – 8 hours (sometimes up to 12) |
| Bioavailability | ~4-20% (lower than inhalation) |
Scientific Considerations:
- 11-hydroxy-THC has higher blood-brain barrier permeability, leading to stronger, prolonged effects.
- Bioavailability is lower than inhalation due to first-pass metabolism.
- Factors such as dietary fat content, metabolism rate, and liver enzyme activity affect absorption efficiency.
1.3 Sublingual and Buccal Administration (Tinctures, Sprays, Lozenges)
Mechanism:
- Cannabinoids are absorbed directly through the oral mucosa, bypassing the digestive system and liver metabolism.
- This results in a faster onset than edibles but a slightly longer duration than inhalation.
| Factor | Tinctures/Sprays |
|---|---|
| Onset Time | 15 – 45 minutes |
| Peak Effects | 1 – 2 hours |
| Duration | 3 – 6 hours |
| Bioavailability | ~20-35% |
Scientific Considerations:
- Sublingual absorption avoids first-pass liver metabolism, allowing higher THC bioavailability.
- Studies show tinctures have more predictable dosing than edibles.
- Effects may be modulated by carrier oils (MCT oil, ethanol-based solutions, etc.), affecting absorption rates.
1.4 Transdermal Patches
Mechanism:
- Cannabinoids are absorbed through the skin and into the bloodstream at a controlled rate.
- Provides sustained, steady systemic release, rather than immediate effects.
| Factor | Transdermal Patches |
|---|---|
| Onset Time | 30 – 90 minutes |
| Peak Effects | 2 – 4 hours |
| Duration | 8 – 24 hours |
| Bioavailability | ~50-70% (steady release) |
Scientific Considerations:
- Transdermal formulations use lipophilic enhancers to increase skin permeability.
- THC and CBD bypass gastrointestinal metabolism, leading to longer-lasting therapeutic effects.
