Methods of Ingestion & Their Scientific Mechanisms
A. Smoking (Combustion)
Mechanism of Absorption:
- Inhalation of Pure Kush delivers cannabinoids directly to the lungs, where they rapidly diffuse into the bloodstream through the alveoli.
- THC reaches peak plasma concentration within 5-10 minutes due to fast absorption into pulmonary circulation.
- The first-pass metabolism in the liver is bypassed, allowing for a higher bioavailability (around 30-50%) than oral ingestion.
Onset: 1-5 minutes
Peak Effects: 15-45 minutes
Duration: 2-3 hours
Pros:
- Fast onset of effects, ideal for immediate relief from pain, anxiety, or nausea.
- Allows precise dose titration by adjusting inhalation intensity.
- Higher bioavailability than edibles due to avoidance of first-pass metabolism.
Cons:
- Possible respiratory irritation brought on by byproducts of combustion.
- Shorter duration than oral ingestion.
B. Vaporization (Vaping)
Mechanism of Absorption:

Cons:
- Requires a vaporizer, increasing initial cost.
- Overheating terpenes can degrade cannabinoids, reducing effectiveness.
C. Edibles (Oral Ingestion)
Mechanism of Absorption:
- THC is absorbed through the gastrointestinal tract and transported to the liver, where it undergoes first-pass metabolism.
- THC is metabolized into 11-hydroxy-THC, which is more potent and longer-lasting than regular THC.
- Bioavailability varies widely (4-20%), depending on digestion, food intake, and metabolism.
Onset: 30-90 minutes
Peak Effects: 2-3 hours
Duration: 4-8 hours (can last up to 12 hours in high doses)

- Discreet method with no smoke or vapor.
Cons:
- Delayed onset, making dose titration challenging.
- Higher potency due to 11-hydroxy-THC increases risk of overconsumption.
D. Sublingual Administration (Tinctures & Oils)
Mechanism of Absorption:
- Cannabinoids are absorbed directly into the bloodstream via sublingual capillaries, bypassing the digestive system.
- Faster onset than edibles but slower than smoking or vaping.
- Bioavailability is higher than edibles (~40-50%) since first-pass metabolism is minimized.
Onset: 15-45 minutes
Peak Effects: 1-2 hours
Duration: 4-6 hours
Pros:
- Faster onset than edibles without combustion-related risks.
- Precise dosing possible with droppers.
- Longer-lasting effects than inhalation.
Cons:
- Bitter taste (can be masked with flavoring).
- Slower than smoking/vaping, making it less ideal for immediate symptom relief.
E. Topical Application (Creams, Balms, Transdermal Patches)
Mechanism of Absorption:
- Cannabinoids interact with CB2 receptors in the skin without entering the bloodstream (except for transdermal patches).
- Topical creams and balms: Provide localized relief but do not produce psychoactive effects.
- Transdermal patches: Allow THC to enter systemic circulation, providing slow-release effects over 8-12 hours.
Onset: 15-60 minutes
Peak Effects: 1-2 hours
Duration: 4-12 hours
Pros:
- Non-psychoactive (except transdermal patches).
- Effective for localized pain relief (e.g., arthritis, muscle soreness).
- Long-lasting and steady cannabinoid release.
Cons:
- Not effective for systemic conditions (except patches).
- Slower onset compared to inhalation.
